Should Site Search results be blocked from search engines?

[pbhatt]

What are the advantages & disadvantages of letting Google crawl site search results? We currently have them blocked via robots.txt, so I'm not sure if we're missing out on potential traffic.

Thanks!

Think about crawl budget allocation that google gave to your website.

by blocking search pages from your robots.txt, your saving alot of budget to crawl and recrawl your important pages. and on the other hand, some instances where search pages might provide indexable URLs with Thin content and your site might be a Panda candidate.

So there is no potential you did a good job.
