G. Sitemaps (2200 not found/unreachable urls + robots.txt question)

Ok i recently imported my phpbb to vb 3.61, and of course added vbseo.
I noticed that in google sitemaps, i have about 2200 urls that are not found. I beleive these urls are for my old phpbb setup.

Are all these broken links (that redirect to home) diluting my pagerank/keywords/etc? How can I make google forget about those urls that no longer exist? I was hoping they would automatically just drop off with the next google dance but that does not appear to be true.

Here is a link to a csv file listing all of my broken urls:

Also, I have about a dozen urls under the "unreachable urls". Here is the link to those: http://www.ruleoneforum.com/uploaded...nreachable.csv

What should I do with these urls? Are they working against my seo?

Finally, can someone verify that my Robots.txt file is correct?

Thank you so very much!

Hello Justin,

I checked your not found URLs list. You can setup a redirection for your old phpbb URLs (thread, post and member pages) to the homepage by adding the into .htaccess right after "RewriteEngine on" line:

Code:

RewriteRule ^\.html$ http://www.ruleoneforum.com/ [L,R=301]
RewriteRule ^(post|member)[0-9]+\.html$ http://www.ruleoneforum.com/ [L,R=301]
RewriteRule ^viewtopic\.php http://www.ruleoneforum.com/ [L,R=301]

Your robots.txt seems to be correct
