What is the effect of placing Google Ads or any other kind at the bottom of the page?With the ads as last element in the page, like placing ads below the half section of the page.For example, some pages would be 2000px long and some would be more than 5000px so it would need more scrolling to get to the bottom...Even if the user reaches the bottom, will they spend time looking at the ads?
Will placing Google Ads at the bottom of the page have any effect?

At one point, Google published a heat map on their site showing the best places to put ads.   They have since removed it because it made it appear that plastering your site with ads was the way to go.  Don't do that, use it to figure out where an effective placement or two for your site would be.  Here is a site that still has it and has revisited the question: http://www.vaughns-1-pagers.com/internet/google-heatmap-2.htmAs you can see, the most effective place for an ad is above the fold in the middle of the page right with the content.   Ads generally lose effectiveness as you go down the page.  The one exception to this is on article pages.   Putting an ad right at the end of the article near the bottom of the page can give the user something to do next after finishing reading.   Unless you have articles and put an ad right after the article, I would recommend putting the ad in a more visible place.
