 * Migrated to WP ([citygonow.com](http://citygonow.com)) but have ever increasing
   404 errors (34,700) to date, out of a total of 35,380 indexed by Google.
 * Google Webmaster indicates the 404 Error URL but when clicked, the redirect works
   fine.
 * Have used PHP redirect as opposed to plugin.
 * Any suggestions ?

 * I can think of two causes.
 * 1) Perhaps some are using www. some are not? What are you using to create and
   submit your sitemap to Google? You may need a tool such as XML SiteMaps Pro version)…
   most basic plugins can’t do that much work (creating a sitemap with that many
   urls’). For example the free version which will create a sitemap up to 500 url’s,
   is taking forever to crawl your site….

 * I gave up after 10:50 and as you can see it will only run for 15 minutes anyway….
 * 2) You may have many broken links…Try using [Broken Link Checker](http://wordpress.org/plugins/broken-link-checker/)…
   that may also have issues with so many links.
 * No matter which or what, make sure you have a full backup (oh boy, check with
   host on that (export file size limits, times etc) and make sure such a site’s
   files and db are successfully backed up)
