If you haven't yet changed your WordPress theme, but are thinking of doing so, please see this article: https://support.ezoic.com/kb/article/changing-themes-wordpress-hardcode-existing-placeholders

But what if you've already changed your site's WordPress theme? Will you need to do anything?

Probably, yes. 

When you change your theme, placeholders may not all translate well across to your new theme, which has the potential to impact upon your revenue.

Our team will be happy to review your placeholder set-up after making these changes, but it can typically take 2 - 3 days for them to optimize this for you.

If you would prefer to get started in the meantime, or handle this yourself, here is some quick information on how you can adjust things from your end.

We recommend reviewing your placeholder setup on your top landing pages with these top tips for optimizing your revenue: https://support.ezoic.com/kb/article/ezoic-ad-tester-best-practice-guide

If there are divs which are no longer available the Ezoic system may have automatically removed some placeholders so it's important that you add additional placeholders in to compensate. The article above has a link to a video on how to do that using our ad tester chrome extension.

If any placeholders have not translated well to the new pages we don't recommend deleting them if avoidable as these may be placeholders which are generating a lot of revenue, but instead try adding padding and changing the sizes which are enabled so that no placeholders are overlapping and that you have at least 1 of every position type per page where there is the content to support it.

After you have made these changes, there may be some impact on revenue in the short term, as the system will need a little time to adapt to the new setup and collect new information about user behaviour and adapt to optimize.

You can use Ezoic's Chrome Extension to make changes to your placeholder set-up. This can be found here: https://chrome.google.com/webstore/detail/ezoic-ad-tester/nbccjeeblefkmoohdiipbghgikopimnd?hl=en
