Crawl Diagnostics

We just look at Google webmaster tool and we having lots of crawl error accessing tabs.
its any solution to fix this? We using nop 3.6 and have version 3.6.463.16828
7,857 Pages with Title Missing or Empty
ProductTab/ProductCustomTab/5
ProductTab/ProductReviewsTab/4366
ProductTab/ProductContactUsTab/4346

Hi,

This URLs shouldn't be accessed by google crowers. Can you try to forbid them ?
This can be done from Nop.Web -> Controllers -> CommonController -> RobotsTextFile action. Just add all the URLs starting with ProductTab/ in the disallowPaths list.

Hope this helps!
