Is it better to put adsense only on selected pages?
Or doesn't it matter?

I have a couple of pages on my site that work very well with adsense. I am also considering to use Adsense as a default campaign for the rest of my site. I'm just wondering if that could actually harm my revenue.

Does anyone know how Adsense works? Will Google serve Adwords regardsless of how many pages of a site a visitor has seen before? In other words, if a user clicks on 10 pages about widgets, will Google display targeted ads on all ten pages, or just on the first five, and then serve public service ads? Because... if the latter is the case, it might make sense to save those impressions for those pages that are known for good clickthrough rates, and put different ads on the other pages...

Not that I know of. As far as i can see, the strategy is to not publish any information as far as possible that could possibly encourage "adsense optimization". I agree to a very large extent as i can see this leading to long term problems, that could degrade ROI for advertisers, degrade the google and adsense brand to the detriment of other adsense advertisers to mention just one "loser", and create a mass of "adsense optimized" sites and pages on the web that are there for very little other reasons than adsense income.

There are various ways however to optimise for Adsense, based on very good guesses and the info they provide already. But i think google is trying to keep that to a bare minimum.

I would advise against creating pages and sites 100% optimized for Adsense. Google can change the rules at any time, and then we will start having those "google is taking food out of my babies mouth's type posts", if adsense reaches any critical mass.

Chiyo, I appreciate your reply, but I'm not sure if you didn't miss my point. I wasn't planning to make or change any pages to perform better with Adsense, or do any sophisticated optimizing.

My main question was: Will those adsense ads wear out, and after a user sees 5 pages about widgets, the sixth page won't have widget ads on them anymore because all widget ads have already been shown? Or can you view 100 pages about widgets on the same site, and the 100th page will still have the same widget ads on it, just like it would have been the first? There's a fundamental difference between these two systems, and I'm sure there are people in here who already know which one applies.

Sorry yosmc..

I should have stopped my prevous post at "Not that i know of" ;)

OR...

Adwords advertisers can set maxmum spends a day. As that max spend is approached their ad may appear less as a percentage. There are other ways that the ads can disappear and reappear, but im only talking about the Adwords side; i dont know whether adsense applies additional "filtering" and if they did, i dont think they would tell!

>>In other words, if a user clicks on 10 pages about widgets, will Google display targeted ads on all ten pages,

As far as I can see, when they have targeted ads, they appear on the appropriate page, and not on others.

If someone has bid for "green widgets" and you have several pages on widgets, but only one page on green widgets, then the tageted ad will appear only on the green widget page (all other things being equal, which they scarely often are)

I have followed it through on hotels, and that seems to be how it works. In the end it depends on what the advertiser is paying for - they call the shots (and rightly so)

Interesting to see how Google goes about pruning (expelling) content sites

To answer your question: NO, Google does NOT rotate ads. If you have 10 pages which happen to trigger exactly the same keywords, all ten will always show the same ads everything else beeign the same. Of course page one shown at the start of the day may be differnt from page 10 shown ad the end of the day as advertisers use up their daily budget, but page 1 and page 10 will show the same ads at the same time.

So you could safely put adsens on all your pages. But it may be worth making sure each page has a slightly different focus, not jsut for more varied AdSense display but aslo from a SEO as well as usability point of view.

No, I do not agree with Killroy.

Based on what I saw, the ads do rotate. However, I assume that it would depend on the ads inventory and whether Adwords advertisers change the bids. If your keyword would be a popular one, you could get enough Adwords to rotate. Otherwise, you would see the same ads over and over.

I have put AdSense on just a few of my pages, and am getting excellent results --in fact, the CTR is so high that it almost worries me! (As I mentioned in another thread, I got an inquiry from GG re. possible click fraud that *may* have been related to the CTR.)

I wonder if the answer to yosmc's question could somehow be related to the "theme strength" of your site.

If your pages are all about widgets --red widgets on one, green widgets on another, blue widgets on the third--, GG could well show the *same* ads (about "widgets") on every page of your site. (Of course, if there is high interest in "red widgets", etc., resulting in sufficient ad inventory for each of the individual color combinations, things may be different.)

However, if your site has pages about widgets, gadgets and... (whatever), the ads may be *different*.

Related to that, if visitors see *several* pages of your site, they may be more likely to develop some sort of "AdSense blindness" if the ads are all the same; but *less* so if they keep seeing *different* ads. ("Curiosity/surprise" factor?)

valortrade> I'm simply quoting Google. And from my own siute I can confirm. While different ads are shown on the same page, that is entirely due to the balancing system of adWords ensuring equal oportunity display for their adwortizers.

If I bid for a keyword of one of your pages, an insane high CPC and per day limit, it will ALWAYS show on that page as first ad for EACH impression guaranteed.

If you get a "rotating" effect on your pages, it maybe that the adwertizers in that niche cannot afforrd a high daily limit and thus cannot ensure to be displayed on each impression.

killroy> I do not think anybody could afford to set "insane" CPC and daily limit with high traffic site and popular keywords.

Also, Adwords advertiser could set geographic target and different visitors from different locations would see different ads.

Hi guys, thanks for all the input! What I have pieced together (both from you comments and from the numbers in my Adsense account) is that placing the Adsense code on one page is highly unlikely to affect the revenue generated by other pages. In other words, I'll be using Adsense as my default campaign as well...
