In my website, most of the pages has a linkedin sharing button written in this way:
<li> <a id="share_linkedin" href="/link/share/linkedin/Dance+Combo+%28Jazz%2C+Tap%2C+Contemporary+Dance%29+%28Age+16+or+above%29" rel="external nofollow" class="share_icon" title="LinkedIn" target="_blank"> <span></span> </a> </li>
I'm sure this is the only code that I use in all the pages for the button.
I also have blocked crawling of all the '/link/share/' URLs in the robots.txt file.
However, I saw many "Restricted by robots.txt" errors in Google Webmaster. These errors are all associated to /link/share/linkedin/ URLs. Almost every day I got hundreds of such errors, I'm afraid these daily errors will cause negative impact on the ranking of the website.
So I'm wonder why google will report error for "nofollow" links, and what's wrong with my codes?
I've got 400 such errors in 4/9/2011 and 370 in 3/9/2011. If there is nothing wrong with the website, then is there an option to get rid of it? Thanks!
