Search Engine Blocked by robots.txt for Dynamic URLs

[CommercePundit]

Today, I was checking crawl diagnostics for my website. I found warning for search engine blocked by robots.txt

I have added following syntax to robots.txt file for all dynamic URLs.

Disallow: /*?osCsid

Disallow: /*?q=

Disallow: /*?dir=

Disallow: /*?p=

Disallow: /*?limit=

Disallow: /*review-form

Dynamic URLs are as follow.

http://www.vistastores.com/bar-stools?dir=desc&order=position

http://www.vistastores.com/bathroom-lighting?p=2

and many more...

So, Why should it shows me warning for this? Does it really matter or any other solution for these kind of dynamic URLs.

It's a warning, not an error. It means "hey, make sure that you really want this stuff blocked" not "you made a mistake". And yes, you really do want those annoying osCsid parameters blocked!
