Bloggers: Effect of Changing URIs on AdSense

This article was written by in Administration. 12 comments.

So as many of my readers know, about a week ago I switched Consumerism Commentary from the Movable Type platform to WordPress. There were a number of reasons for the change, including MT’s long rebuild times for example.

Since this migration caused a slight change in the URIs for my entries — namely, the underscore characters became dashes — I had to write a small script to handle the translation so no links from outside would be broken. Even though I was changing software, old link to my blog still needed to work and not produce an error.

Doing the translation wasn’t as easy as doing a “permanent redirect” in .htaccess — I had to write a PHP script that is called from .htaccess whenever underscores are encountered in the URL. The script replaces them with dashes and redirects the browser back to the server, where .htaccess is interpreted again.

Basically, the links weren’t broken, but I lost my Google Pagerank on almost all of my pages.

I saw the effects immediately. My daily AdSense revenue tanked to sometimes less than 50% of what was expected. This has been the case almost all week, but the last few days, it appears as if things are returning to normal. I’ll have to wait another few weeks to determine if there is any more fallout from the change.

The improvements seemed to coincide with when I installed the WordPress plugin that enables a Google Sitemap, so perhaps that was the key.

Today’s earnings are pretty high for a Friday so far.

We’ll see what happens. There are worse things that could happen in the world than Google not paying me as much as they had been.

Was it just google that your pages had to be re-indexed with or was it Yahoo, MSN as and all the others as well?
