More than a month ago moved to WordPress with a DB import of 9200 articles. Reading up on permalinks I decided to use %postname% as the best permalink structure for SEO.
Traffic has gone from a steady 2500 pageviews a day to a steady 700 pageviews a day.
Google bot has indexed the 9200 articles with the new structure.
Google Tools shows 1000 server errors about /categorey and /authors.
Google Tools also shows 350,000 urls not found, most seem to be /archives. It is now also showing a DNS error and refuses to crawl.
This is the new permalink stucture google has successfully indexed
This is the old permalink that most of the 9200 articles have out there.
A simple .htaccess 301 access /archive does not work because of the number and the slash.
Any advice or direction to help would be appreciated.
Will changing the structure to follow the old urls help?
