If you’re running Google AdSense Ads on a site, you would’ve definitely come across the situation where sometimes either no ads show up or completely irrelevant ads come up. And what do you do ? Well, like many of the webmasters, just sit back relax and hope that things would improve.
Looks like Google understands it, and now has openly admitted that this could have happened because of your mistake rather than theirs. Not just that, they’ve come down for your help too.
Google is running a series of AdSense Help articles to help webmasters who have problem optimizing their AdSense ads. And this time around they’ve addressed the issue of AdSense ads not showing up sometimes. Listed below are the factors that Google think might be preventing from Ads showing up on sites. Take a look, they’re insightful even though basic.
- Did you just add the code to that page? Relevant ads should appear on your pages shortly after you add the code, but sometimes it can take up to 48 hours for ads to show. This is because our crawler has to visit your page and determine its content so we can serve targeted ads.
- Does the code on your page match the code in your account? Make sure to copy the code exactly as it appears in your account, and paste it within the body tags of your HTML code. Be sure not to make any changes to the linebreaks of the code (e.g. pasting the code all in one line) as this will break the code and prevent ads from showing entirely.
- Are you using an HTML editor? Publishers often use a design-enhanced HTML editor like Macromedia Dreamweaver or Microsoft FrontPage (aka WYSIWIG, “what you see is what you get” software). If you use such an editor, you may see errors if you paste your ad code into a WYSIWYG view such as the “Design” or “Layout” view. For the ads to function properly, you’ll have to copy and paste the ad code into the HTML source code of your webpage using the editor’s HTML view or HTML insert function. Check for any additional tags inserted by the system or changes in the linebreaks.
- Are you using a content management system (CMS)? If you have trouble implementing AdSense with a specific content management system, we recommend searching for the name of the CMS (eg. Drupal, WordPress) and ‘AdSense implementation’. You can also ask in the forum if other publishers have mastered similar problems, or contact your program provider directly.
- Are the ads inside nested frames? While you can choose where to position your ads on your pages, be sure to avoid embedding the ad code in excessive div tags or nested frames. Depending on your browser settings, implementing your ad code in this way might prevent ads from appearing correctly.
- Is your page dynamically generated? If you’d like to implement AdSense ads on a dynamically generated site — for example, a site with session IDs or pages behind a login — you should take a look at this Help Center entry for more information on how to receive targeted ads.
