What is eCPM ?

eCPM(Effective Cost per Thousand Impressions)- what exactly is that?

eCPM is a bit of industry shorthand that seems here to stay. You've seen it listed in your AdSense reports; it means, "effective cost per thousand impressions."eCPM is calculated by dividing total earnings by total number of impressions in thousands. It is a great performance measure for your various ad units, so when experimenting, you can use eCPM to compare your results.eCPM and CTR (Click Through Rate) is also probably closely watched by AdSense.

On the other hand, it is used to gauge the effectiveness of your ads. If you have optimised your ads properly, have good content and have used keywords effectively which attract high paying ads, you may be high
earnings for clicks even though the no of clicks are low, and that will give you a high eCPM. On the other hand, if you have got low paying ads, you may be getting low earnings or even public service ads for which no earnings are given even if you are getting a high no. of impressions, then you will have a low or even zero eCPM.The eCPM is very important for pagerankings.eCPM and CTR (Click Through Rate) is also probably closely watched by AdSense.

*********** ********************* *************
Details :

eCPM can be a useful statistic to track ad performance.For example, let's imagine we have two custom channels named 'Blue Skyscrapers' and 'Red Rectangles', respectively, which reflect the types of ad formats we're testing on our site. During our test, the 'Bl
ue Skyscrapers' channel receives 370 page impressions and $1.48 in total earnings. The 'Red Rectangles' channel receives 187 page impressions and $0.97 in earnings over the same period. To make these figures more comparable we calculate eCPM -- i.e., the estimated earnings for every 1,000 impressions received. We find that eCPM for blue skyscrapers is $4.00 while the eCPM for red rectangles is $5.18.

This means if we received 1,000 impressions of blue skyscrapers, we would earn roughly $4.00. But for 1,000 impressions of red rectangles, we would earn about $5.18. Therefore, assuming that our sample size is large enough, it is to our advantage to switch to red rectangles throughout our site because they generate more revenue per impression.So watch over with your eCPM.

It can be easily calculated.

eCPM = earnings devided by number of impressions multiply by 1000.




Important Topics:


If you are getting very high eCPM, but a very low CTR, your earnings may have been driven up by a lot of invalid clicks from just a few impressions. This may cause AdSense to examine your account closely.

However, a high eCPM with a low CTR may also mean that your site is getting a lot of high paying ads because you have keywords which attract high paying ads, or have optimized the color and the positioning of your ads. So whether Google really pay attention to your eCPM is only guesswork, but for you, it is a good indication of the effectiveness of your ads in your site.

******************** ***************** ***************
Excel to find out eCPM :


To make the meaning of eCPM clearer some hypothetica examples are given below. The eCPM was calculated by using the formula eCPM = earnings divided by number of impressions multiply by 1000 (in the C2 cell, typing the formula C2=A2/B2*1000) with MS Excel:Google AdSense eCPM
The figures for eCPM in the last column above was calculated by Excel using the formula =a2/b2*1000 for the second row, and similar
calculations were done for the earnigns in the following rows, except that they were given in 2-digit figures.

Another hypothetical example:


Calculation of earnings using figures given for eCPM and Page Impressions
The earnings, in an actual reports may shows $0.00, leading one to think that nothing were earned for the impressions. The figures for the earnings in the above hypothetical example above were calculated using the formula earnings=eCPMxPageImpressions/1000 in the second row. Note that if the figures rounded up to 2 digits will end up as $0.00. That however doesn't mean that you didn't earn anything even though the number of clicks is zero, but you earn an amount too small to show in the Earnings report as it was rounded up to 2 digits. You actually earned something from impressions generated which are accumulated and paid to you.

What is CTR?




CTR Definition :


Click Trough Rate is very important who wants to increase page rankings.CTR (Click-Through Rate) is the number of times an advertisement is clicked upon over the number of times the advertisement is served. Typical click-through rates have been declining (a click through rate of 1% would be very high). The click-through rate will determine the cost of an advertising campagn that was based on CPC and CPA.

On the other hand, short for click-through rate, the ratio of the number of times a user clicks on an online advertisement per number of viewers who view the Web site that has the advertisement on it. For example, if one out of 100 people who visit a specific Web site click on an advertisement and are taken to the advertiser's site, then the CTR of that advertisement is 1/100, or 1%.Thats the way google make CTR% for your pages.

A Good CTR in Adsense :

The problem with comparing CTR (and in fact a lot of Adsense statistics) is that every blog is so different that any such comparison can be problematic - and at times pointless.

Why is comparing Adsense CTR between sites a problem?

(1) CTR varies between topics - one of the things I learned in my early days with Adsense after using it on multiple blogs was that despite having the same design on a different blogs, CTR could vary incredibly between one blog and another. One of the reasons for this is simply the topic of the blog. For example some Adsense publishers find that sites with products as a topic tend to get better CTR than sites with non product related topics. They argue that people are more likely to click an advertisment if they are in buying mode and see an ad that might meet their need.

(2) CTR relates to Ad relevancy - if I have a blog about ballpoint pens that has ads for ballpoint pens I have a higher chance of a click than if my ballpoint pen blog has ads for dog food on it. In most cases, the more relevant ads are to the topic of your content - the more likely you are to get clicks. Reasons for ad irrelevancy vary between blogs and might be something that is to do with your blog design (too many uses of the word ‘blog’ for instance triggers blog ads on virtually any topic) , your topic (some topics are difficult for Google to discern) or some problem at Google’s end (I’ve heard of one or two cases where bloggers have written to Google to ask about irrelevant ads and Google have made some changes to fix it).

(3) CTR can vary seasonaly - for example - many blogs report higher CTR on weekends (but lower impressions). Some find that holidays or the lead up to them (eg Christmas) can produce large variations in CTR. These variations can vary from blog to blog considerably.

(4) CTR varies between reader types - It is well documented that blogs and websites with high levels of loyal (repeat) readers tend to get lower CTR than sites with higher levels of search engine traffic. As I’ve written recently - this is because loyal readers can become blind to your ad positioning and design and because SE readers tend to be searching for some specific information that they often want to take some action over - this puts them in a hightened information gathering mode and more likely to click on an ad. Another reader type variation is readers being referred from other sites. I find that these sorts of readers can go either way depending upon what the site referring is but generally CTR is lower. For instance when I get a link from Slashdot I generally expect a pretty low CTR as such a link brings masses of traffic from some pretty tech savy readers who in general don’t click ads much.

(5) CTR varies between ad design and placement options - one massive factor for CTR is the positioning and design of your ads. For example if you put your Adsense ad at the bottom of your page where no one will see it you’ll get a very low CTR - whereas if you position it in a spot where it will be seen it will get clicked on more. The same goes for the colors you choose - select the right colors and you’ll improve CTR.

(6) CTR varies depending upon other site design factors - you can impact the CTR of your ads by using other visual factors. You need to be careful here not to be seen to be encouraging your readers to click ads - but many Adsense publishers have found subtle ways to draw their readers eyes to ad using images, shapes, color etc. One good tip that doesn’t break Adsense TOS is to use spaces around your ads. Studies have shown that ads tend to perform better on a white background with white space around it.

(7) CTR varies depending upon other options to ‘click’ - if your page has no outbound links except for your Adsense ads - the chances are increased that those will be the links that people click on. I was chatting with one person last week who has such a site. He is able to drive traffic to pages on his site with useful content but no other outbound links so that when his readers finish reading his content they either close the browser, hit ‘back’ or click an ad. His CTR was higher on these pages than on others. Of course there are downsides of this approach as his blog is very insular and not interlinked which means SEO is difficult for him.Following this way you could increase your page CTR.



Secret topics about how Google Ranks Websites




The secret topics about to know page raninkgs for devoloping page ranks.
Though Search Engine Optimization (SEO) you might have heard about it this June, but I thought it bore repeating. The secret is out on much of what Google uses to rank your website on their search engine. Reading the actual patent information released to the public, see Google’s patent for their search engine ranking technique from 2005 on evaluating historical documents and the latest patent release from 2007 which includes the new TrustRank.


The Link:


Links have always played an important role in determining citation value. Incoming links help judge the value of a document. The more citations, or links, the more important and valuable it must be. But Google adds some criteria to those citations.

In past the number of incoming links scored high, but a judgment on quality of the incoming link source was added to the mix. If the linking page and site had a high page rank value itself, then clearly, it knew a good thing when it linked to it. Still, this link quality aspect became harder to define as so many sites were joining the web and the quality became diluted.That was past!

Now historical factors play an important roll in addition to the number and quality of the incoming links. It seems Google’s method includes counting the moment a new site is discovered and applying an aging process to the site. Google monitors the link as it changes over time, the speed at which the site adds incoming links, and the life span of the link. It isn’t about having thousands of sites that link to yours, but about building those thousands of links over time.

The aging process that monitors the history of the links and site helps to combat spam sites. Spam sites tend to come and go very quickly, building links fast through their spamming techniques, then closing down and moving on. Thus, the older the site and the links coming into it, the more points the site may get. The shorter the life of the site domain, no matter how many millions of links are coming in, the less Google is interested.So link is very important.

Google monitors the historical value and the slow building of value of incoming links, and they also monitor the changes in the link anchor text over time and throughout the site.

Important(about java/html);
Consistent link anchor text scores low. This is considered “Anchor Spam”. What this means is that if you use the same text in a link, such as perfume salse consistently through your site, then it won’t score very high. If you vary the link anchor text, especially over time not just within the same page, your odds will increase as Google monitors the changes in links over time. Generally, it is recommended to change the keywords in your anchor text around the top 5-10 keywords, to maintain consistency with keyword rankings and link rankings.

So the perfume sales might include link text such as:

* cologne market
* perfume market
* cologne sales
* fragrance sales
* sales of fragrance

This is how changes the whole landscape. The idea of link exchanges and link spam as a method to attract Google’s search engine bots just doesn’t work. Age before linkage.

Word Press Blogroll Tip:

The WordPress Links Manager allows you to set your blogroll links to change randomly with each page view. If you have a huge list of links in your blogroll, consider setting this to random so the links will change, appearing less like link exchange spam. Check out the other options in Links Manager for only showing updated links and other features.

Google also states very clearly that exchanging and buying links won’t work. They know the tricks and techniques. Also, getting links from documents that have no content, just links, also won’t work. Links without content won’t score high.

Now, does this mean that if you link to a page and they link back to you, your scores will go down and it might be considered link spam? No. The other criteria goes into effect to help offset this normal linking techniques. But it does impact the concept of the Blogrolls, which are sometimes considered link exchange lists. So choose your link exchanges wisely and avoid hundreds of links from your site to others, or being on a list of hundreds of links.

Domain Age:


One of the other criteria is the age of the domain. Again, driven by spam sites which pop up and die off quickly, the age of the domain is usually a clue they tend to be in for the long haul.Domain is npw very important topics to disscuss with.

But this causes some problems. If you change your domain name, then are you back at the bottom of the barrel? If the rest of the criteria stays the same and your content maintains consistency, as does your traffic and incoming links, then this might just be a temporary drop and the rise will happen again soon.

Many hosts offer special rates for long term hosting and domain registration. Consider registering your domain for at least two years, five is better. This means you need to make sure that the domain name you choose is one you can live with for two to five years. You can change hosts, but the domain registration needs to stay the same, and stay in your name over the long haul to score points with Google.

Click Through Rates(CTR%):

The click through rate (CTR) of your site may play an important roll in adding up good points on your Google Search Engine score card. The CTR is the rate that people click “through” to your site. Referrer statistics are the numbers and methods visitors use to visit your site. This information tells the site administrator, and Google, from where did you arrive from to land on this site. Did you click through from a search engine (which one), directly, from another site (which site), or, as revealed in the patent, from the cache, temporary files, bookmarks, or favorites of your Internet browser.

Most importantly the click through rate is also based on the CTR of the advertising on your site. The more ads which are clicked, the higher your score.

The CTR is also monitored for fresh or stale content - in other words, are they visiting new content on your site or old posts or articles? Trends and seasons are also taken into account as certain subject matter gains precedence with the time of the year and the current fad.

Trends, Fads, and Seasons:

Built into the Google page ranking technique is the ability to track current and historical trends, fads and seasons. If your site deals with beach wear, the odds are that it will have more traffic during the beach wear season of summer than it will into the fall and winter. This seasonal traffic is taken into account and you may not lose rank when the traffic dies down seasonally.

It also tracks whatever is hot in trends and fads. Right now, everything to do with Hurricane Katrina is hot, hot, hot, but a couple years ago, everything and anything to do with protecting you and your home from biological terrorism was top of the list. Paris Hilton was top of the charts for a long time, doing battle with Britney Spears, but now, both of them are old news.

This is an interesting aspect of page ranking. If your site continues to push keywords long past the fad’s life span, then this could be seen as keyword spamming. Yet, using trends and fads keywords as they come and go could attract attention. Luckily, the rest of the criteria in the page ranking evaluation can help to clear out abusers of keywords related to the current fad or current event.

Posting Frequency :

How often you update your pages and add content is monitored over time. It isn’t just how much but when. If you update or add hundreds of articles within a very short time, this is suspicious, but if you rarely update your site or add content over time, then your ranking will probably drop. Finding a happy medium is still a hit and miss angle, but the information seems to point to consistency not just random spurts of energy.

If you consistently add content once a week, and it stays steady, then it is seen as stable. If you add content consistently every day, and then it drops to nothing, then this change indicates an instability. If you do hit and miss content updating and additions over time, and then suddenly post a ton of activity, this can also be seen as instability and suspicious. Steady and consistent, no matter how frequently, adds weight to the score.

Many researchers say that frequent new or updated content carries more weight than infrequent changes to the site. I could find nothing in the patent that lent proof to that theory, but showing consistent activity does work.

A “stale” page is one that is old and rarely attracts interest. A “fresh” page is one that is new, and will be watched to see what kind of interest it may attract. By updating a stale page on your site, you may attract new interest by rewriting or structuring the information and keywords to attract more attention, breathing life back into the page. Google monitors this “refreshing” of pages to show activity and an increase in interest, scoring high.

Not all “old” pages on your site need updating. If it is still attracting decent traffic, then leave it alone. It is working for you.

The patent also reveals that stable pages that are working which suddenly attract a “spike” in the number of incoming links or click throughs may be an indication of a change of site ownership or spamming. Google evaluates not only the content but the historical changes in the content of the page and the site and if the changes are dramatic and sudden, then the site will rank lower. Stability over time scores higher.

Keywords Still Play a Roll :

Keywords and keyword density still play an important roll in evaluating the content and content history. Putting keywords in titles, links, headings, tags, and throughout the page is still critical to the success of your site’s page ranking and keyword ranking results.

Changes to keywords, by arrangement, closeness, and inside of links, titles and headings are also monitored, much like link anchor text. Consider reviewing and updating your keywords and checking their density and use throughout your site on a regular basis, if search engine page ranking is important to you.

In upcoming posts, we’ll discuss how to maximize your keyword density in your blog posts.
Rank by Traffic, User Behavior, and You

Like other comparative search engines, Google’s patent also tells of how page rankings are compared across the board and monitored over time. The traffic is recorded and monitored. How much traffic each page gets as well as the overall site.

User behavior is checked. Google keeps track of how long visitors stay on your site and from what pages they exit your site. You also get points for bookmarking or adding to favorites.

Keyword search results are constantly monitored. What keywords brought the visitor to your site and what keywords they used to search once on your site.

But “you” also play a roll in determining the page ranking with Google. The domain registration information is checked and compared to the information on the site to make sure the two match. The address of the domain owner may help localize search results to that specific geographic area.

How you have your site hosted also is among the other administrative items checked off. Shared IP host addresses run a risk since they are shared. If someone else is using that server for spamming or other evils, you could also be punished. Dedicated hosting is very expensive, so make sure you choose a reputable host who is publicly and actively stopping spamming sites if you choose shared hosting.

The validity of the site’s code and structure plays a small part, but is still part of the criteria. Make sure your site’s code is validated, checked for errors, and friendly to search engines. Any errors in your page structure or code can easily thwart a search engine’s process through your site. Table designed sites rank low while CSS based designs are much more search engine friendly.

Spelling:

Spelling is still important. Not that Google’s patented page ranking process includes a spell checker - words that are not recognized get dumped. If misspelled keywords are among your missed spellings, then your site will be hurt in the rankings.So beaware about spelling.

What is page ranking ?

PageRank:

What is page ranking? It's defination is not really different to all but what is said by google?

PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page's value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at more than the sheer volume of votes, or links a page receives; it also analyzes the page that casts the vote. Votes cast by pages that are themselves "important" weigh more heavily and help to make other pages "important".

There are many defination of page ranking.In other words, a PageRank results from a "ballot" among all the other pages on the World Wide Web about how important a page is. A hyperlink to a page counts as a vote of support. The PageRank of a page is defined recursively and depends on the number and PageRank metric of all pages that link to it.Mainly incoming link. A page that is linked to by many pages with high PageRank receives a high rank itself. If there are no links to a web page there is no support for that page.

As google assigns a numeric weighting from 0-10 for each webpage on the Internet; this PageRank denotes a site’s importance in the eyes of Google. The scale for PageRank is logarithmic like the Richter Scale and roughly based upon quantity of inbound links as well as importance of the page providing the link.

There are numerous academic papers concerning PageRank have been published since Page and Brin's original paper.In practice, the PageRank concept has proven to be vulnerable to manipulation and extensive research has been devoted to identifying falsely inflated PageRank and ways to ignore links from documents with falsely inflated PageRank.So be aware about page ranking.Many people do not know about page ranking so they couldn't do so with their site.
