Penguin Update or URL Error - Rankings Tank

[chronicle]

I just redid my site from Godaddy Quick Shopping Cart to Drupal.  The site is much cleaner now.  I transferred all the content.

Now my site dropped from being in the top ten on almost every key word we were targeting to 35+.

I "aliased" the urls so that they were the same as the Godaddy site.  However when I look at our search results I notice that our URLs have extra wording at the end like this: ?categoryid=1 or some other number.

Could this be the reason that our rankings tanked?  Previously on the godaddy site the results didnt show this.

I'm going to "guess"  it's not the penguin but a url issue. I've moved around 20 sites to a different platform and it's never been a totally seamless transition as far as google is concerned (none of them Drupal however). Also check your sitemap. (the url that google thinks it is).  I think you may see a 404 error.

Not sure if this is relevant but you might check out this known issue:

Known Issues

• While Sub-pathauto works when drupal_get_normal_path() is called, if drupal_get_path_alias() is called, the hook to alter URLs is not invoked. Functionality that uses this function to compare things like page visibility settings will not match the sub-path processed URL. This is due to core bug #1248626: drupal_get_path_alias() does not invoke url alter hook while drupal_get_normal_path() does.

Good Luck . From one hyperfocuser to another
