When I go to my Adsense account in the Chrome browser, it offers you the ability to check: Multi-screen Site Health Revenue Optimization which appear on right-hand side of that screen (under Scorecard). My question is, when I click "Revenue Optimization", it allows you to check "Crawler Errors" and "Text and Display ads" and "Recommended Ad Formats". I want to be certain my "Revenue Optimization" is at it's optimum settings, but when I click CRAWLER ERRORS>FIX CRAWLER ERRORS (which has a red exclamation point!), nothing opens, it's as though that link won't allow me to the next page to fix crawler errors (usually my luck)....why? I note at bottom tool bar when I mouse over the link, I see the word "javascript:;" - connot figure that out. Need any help I can get on fixing the so-called crawler errors
