Should I block Map pages with robots.txt?

[imaginex]

Hello,

I have a website that was started in 1999. On the website I have map pages for each of the offices listed on my site, for which there are about 120. Each of the 120 maps is in a whole separate html page. There is no content in the page other than the map. I know all of the offices love having the map pages so I don't want to remove the pages.

So, my question is would these pages with no real content be hurting the rankings of the other pages on our site? Therefore, should I block the pages with my robots.txt? Would I also have to remove these pages (in webmaster tools?) from Google for blocking by robots.txt to really work?

I appreciate your feedback, thanks!

Hello!

I would definitely suggest disallowing these pages from being indexed in your robots file. These 120 pages will be considered duplicate content, and will most likely will also be duplicate titles and meta descriptions. Duplicates of any kind is a huge SEO problem.

Once you edit your robots file, you will not need to do anything in your webmaster tools. The site will be crawled according to your robots file.

Another idea… depending on your URL structure, you may be able to use canonical tags to stop multiple pages that are seen as duplicates from being crawled. That way you won't have to completely stop the indexing of these pages by disallowing them through the robots file.

Hope that helps!
