Around eight months ago I revamped my site www.exchangeandplant.com and upgraded from Classic ASP to ASP.NET webpages. The Google spider crawled through all the new .aspx pages of the revamped site and updated it well. Couple of months ago we made some changes to the titles, description of our pages. Since then, my sites pages were dropped slowly day by day from the Google index. And it seemed like no new pages of my site were crawled after that. Now all the current pages of my site are dropped from the google index and the old classic ASP pages have been restored. If I search the term "site:www.exchangeandplant.com" I can only see my one year old outdated pages and URL's in the results page. None of my new URL's are found in that page. Although I've been using Google XML Sitemap and updating it regularly for past 5 months, I couldn't find my current URL's in the result pages. I don't know how to get my current site's pages back in the search results instead of the old outdated pages. To my biggest surprise, after the July 13th pagerank update all the pages except the homepage have lost PR. I can't even find those pages in the current google cache. I tried every possible way I know to make google crawl my site, but still not succeeded. It's really painful to see all the pages of my site PR0 except the homepage. I informed about this to Google last month and yet to receive a reply. Please help me to solve this issue.
Wow. That's not good. As captain Jack would say, "Oh, BUGGER!" Try doing a permanent redirect from each of your old pages to the corresponding new page.
Thanks for your quick response. It would be hard to permanantly redirect each page as it's a dynamic (querystring based) pages and most of the records are not even available in the current database. Sample Old URL: www.exchangeandplant.com/machinery_dealers/machinery_dealers_company_detail.asp?id=955 All my old outdated pages are going to the NotFound.aspx page which has a 404 error in the header. Wouldn't that enough to tell that the link was an old link?
I'm also waiting a lot for Google to index my new site. It indexed one day about 30 pages of 2000 and then suddenly stopped ?!
Can you at least do a 301 redirect on the NotFound.aspx page to redirect to your main page, and let your visitors attempt to find what they're looking for from there? I feel your pain, as Google is doing the same things to us.. Total nightmare!
