Overly Dynamic URLs

[bobbabuoy]

I have a site that I use to time fitness events and I like to post the results using query strings.  I create a link to each event's results/gallery/etc.  I don't need these pages crawled and I don't want them to hurt my seo.  Can I put a "do not crawl" meta on them or will that hurt my overall positioning?  What are my other options?

If you add the rel="nofollow" tag in your html in the surrounding container of the link then google will not let it effect your ranking.

With "overly dynamic pages" means the search engines might have a problem crawling them.

They will not hurt your seo unless they have poor content, duplicate content etc. So if I were you I wouldn't worry too much.

However if you don't want these pages crawled you can exclude them in your robots.txt file.

Also add a meta tag in the header of these pages to have them removed from the index.
