Will this help increase the relevancy?

Just a thought.
If you are using a automatic generatic language like PHP. I think the webpage does not load almost instantenously, so therefore, adsense bot does not scan all of the content before displaying the ads, thus the relevancy may be low as compared to static webpages.

But, if you can make a code such that the sequence of generation is like this;
1. header
2. body (main content)
3. body (adsense)
4. footer
do you think the relevancy will increase since the content will be generated first before the adsense code will be generated? Thus, adsense bot will have enough time to scan your content and find related ads.

what do you think?

After a visitor loads your page for the first time, AdSense Mediabot is triggered when the javascript code for the AdSense ad block is loaded. As you might have seen in your server log files, the Mediabot re-requests the page from your server and tries to analyze it on the fly. So it is not the javascript executing in the visitor's browser that analyzes the page, but a second independently requested copy of the page is sent to a special analysis server. If this server is able to determine very quickly which keywords are there, an adblock will be filled, otherwise a PSA will be shown.

In the situation mentioned above, it could be benificial to have the AdSense code at the top of the page, because this might cause an early trigger of the Mediabot and the Mediabot already starts analyzing when the page is not fully loaded in the visitor's browser. This might increase the speed somewhat at which the ad block is shown.

This above scenario is only true the first time a visitors loads the page. If Mediabot already visited a page in the past it will not reload and analyze the page, but instead use the keywords it determined previously. In that case the location of the AdSense block is irrelevant for the Mediabot triggering.

You are thinking technically how Google's Crawler and Media bots work. But I am sure that Google must have thought of this situation already and after seeing the whole content of the webpage, it will show you the ads.

Yes, if you arrange the content that way, you will make Google's work a bit easier (Technically). SEO wise, you are perfectly sound.

I agree with your thought

MediaBot is not something thats installed over visitor's PC. It has to crawl your website in anyway. According to my experiments, MediaBot is a small version of GoogleBot which is just there to detect the theme of the webpage. Google bot is the mother of the MediaBot cause Googlebot does many more things than just realizing the theme of the website, like counting its inward links, ranking and indexing and all that stuff that is known or not known.

Mediabot's purpose if to detect the theme of the page only and keep checking after every 15 days if the theme is same or not. So, it dosent matters if page is loaded later or sooner. Mediabot is going to crawl your page and display ads according to that only, according to content, not according to the place of your content. After when Googlebot crawls your webpage, relevancy increases and so does the payout I guess (atleast to me, but alot of factors count in).

SEO wise, what you are saying, is making perfect sense. and its good to put the content on top and Adsense on the bottom. Mediabot is going to be initiated in anyway. It wont be initiated again and again, just a few times only.

I agree with lammert, its irrelevant where you place the Adsense code. Mediabot has no effect on where you place the code, but if you can make the work of Googlebot easier, then why not?
