    This is a little trick I stumbled on quite by accident a few months back, and has increased my CTR from 2%, to over 20% on average over the past 4 months.

    It is so simple, yet effective and is definitely BlackHat, and may put your account at risk of being banned, so be warned.

    The main put off for many visitors to a site, is the 'Ads by Google' on the bottom of all your ad blocks which deters them from clicking. Now, I have a quick trick to remove this from the bottom of the ads.

    Step 1. You need to create an ad using the old style google code directly on your website (still a favorite for most webmasters). You may already be using this method, as it still provides by far the best flexibility in terms of layout and colour choices.

    Now, say we have a 250x250 ad. You would have a code block similar to this:
    Code:
    <script type="text/javascript"><!--
    google_ad_client = "pub-xxxxxxxxxxxxxxx";
    google_alternate_color = "#FFFFFF";
    google_ad_width = 250;
    google_ad_height = 250;
    google_ad_format = "250x250_as";
    google_ad_type = "text";
    google_ad_channel ="xxxxxxxxxxxx";
    google_color_border = "#FFFFFF";
    google_color_link = "#0000FF";
    google_color_bg = "#FFFFFF";
    google_color_text = "#000000";
    google_color_url = "#000000";
    google_ui_features = "rc:0";
    //--></script> 
    <script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> 
    </script>
    Step 2. To remove the Ads by Google message, all you need to do is subtract 20 from google_ad_height. In our example google_ad_height would thus be 230.

    After this simple change, you will still get the complete ad, but without the Ads by Google message. This has greatly increased my CTR with this simple change, and it works with all the ad block sizes. (I only use text ads btw)

    Now, on a more technical note. I am not sure how closely google monitors the parameters on their ad blocks, so I've taken the safe route and instead of changing the google_ad_height variable, I instead leave it as-is and put the adsense in an iframe with a 250 (width) x 230 (height) dimension. This produces the same results, but is easier to get away with.

    Even further I have put in safety measures to detect various spiders (google bot, mediapartner spider, etc.) and show the proper 250x250 iframe for them. This may be something you could consider doing as well.

    This is going on month 5, with no issues as of yet. YMMV.

    As a note, having an adsense on a webpage (ie. /ads.php) by itself, and inserted in an iframe still works as well as having the adsense code directly on the page. It will still show reliant ads for the page being displayed.

    I hope you find this helpful. It has done a great deal for my sites.

    hmmm thats a really interesting tactic. I wonder if Google will clamp down though, because youre not supposed to edit the code at all

    This is why the outer iframe. It is not directly altering any google code.

    By editing the size, thats altering the code.

    "Any AdSense code must be pasted directly into webpages without modification. AdSense participants are not allowed to alter any portion of the code or change the behavior, targeting, or delivery of ads."

    There is a level of grey area to this, which is why it's a (very effective) blackhat technique. I consider this method much more ethical than other methods, such as image overlay, etc.

    you break 2 tearms from adsense tos (no ads in iframe and do not remove logo)
    so you can expect to be banned soon

    iframe adsense has become quite popular, specifically in CMS software that cannot insert javascript, etc. Google seems to shed somewhat of a blind eye to iframes from what I can tell, and what others are doing, though I am certainly no authority on the matter.

    With regards to the logo removing, yes, this is against the tos, which is why I mentioned the warning, and precautions you can take to protect yourself (At least against automated review). This will not pass any manual review however, so it's best to keep the CTR down under the 10 - 20% marker.

    YMMV. It is an interesting technique I've not seen used anywhere else, and it works. Google may pick up on it some day if it becomes wide spread however.

    Actually you can do it with simple frame tag as well so you can keep your ads on same page.

    There are bound to be several ways to accomplish this.

    One thing I do however, is my iframe is designed for ad rotation, and as such can (and sometimes do) show CPA ads that are of different heights and widths to standard adsense ads. If google ever questions me regarding my hidden google logos, I can simply tell them it was an oversight. I only do this on the main content ad (the eye catcher), the other adsense ads on my sites are all left as-is.

    I use this technique on 13 or so of my WPMU autoblogs without issues for almost 5 months now, all using 1 adsense account.

    My CTR is not forced, and is from organic traffic, so it is of high quality. If people are tricked into clicking, then google may open a wider eye, it's hard to tell.

    Having a backup adsense account is recommended, and thankfully something I do have just in case.

    This is very interesting thanks for sharing. I'm going to look into coding this for myself. A couple questions for you:

    Your "eye catcher ad", is that center page? Also how often do you rotate your ads?

    Hadn't thought of that.. very sneaky and clever. I guess the only thing that worries me a bit, is we're (you in this case) outlining all these BH methods and G can just come here and look. Doesn't mean they will.. but they certainly can.

    @Cutlass
    My main ad is in the top left of the page, just under the title. I rotate the ads depending on where they come from. People searching from google or other engines get adsense. If I'm promoting a special offer in twitter or facebook, then those people get the CPA offers 90% of the time as they do not seem to click on the adsense ads as much.

    @Showbizvet
    That is true. It would be nice if this thread could perhaps move into a members-only section. I'm sure there could be google engineers as members here too.. you never know. The conspiracy theorists could go crazy over this lol.

    Best way to lower your CTR is to remove the ads lol. What I've had to do on occasion is rotate to more CPA than adsense until my CTR is lowered.

    Google hates blackhat, and anything to do with others making a profit. I'm sure they will not like this technique at all.
