    Too many adsense blocks?

    I see sometimes when I have too many adsense units - 3 ad blocks and 2 link units - some of them on most important placements aren't displayed and that might hurt the ctr. Is it better to use less blocks?

    What I mean is that adsense is simply not displaying ads on all the blocks. Not enough ads? I dun't think so it's a competitive niche, but some are empty

    Some ad campaign owners only want certain countries to see their ads.

    One of the most important things with a good AdSense layout is making sure that the ads are listed in most-important to least-important order in the source code.

    AdSense loads ads in the order in which they occur in the HTML source. Therefore, if you have three AdSense blocks and Google can only find ads enough for two, the least important block won't get ads.

    The other aspect of this is that AdSense places the most expensive or best performing ads in the first AdSense block in the source code. The first ad in the source code should always get your best placement.

    If you have a 468x60 banner ad in the header and a 336x280 rectangle ad in your content section, you have to be very cautious that your CSS isn't destroying your earnings. If the 468x60 appears first in your HTML source code, it will get the best paying and highest performing ads -- even though it is an inferior ad placement. The 336x280 in-content rectangle will have your best CTR, but with lower-priced ads -- because the higher priced ads are being wasted in your 468x60.

    This is not easy to explain or understand, but it is very important for optimizing AdSense earnings.

    Yeah that makes sense.
    Does that refer to link units as well? Because they only show links and not ads.

    Link units use the same FIFO queuing mechanism, but they have a separate queue.
