OK, thanks a lot, guys. Just wanted to make sure that its provided data is accurate.
It shows violations like "excess of using h1 titles" in a page that includes page lists with h1 heading per each or it says title tags shouldn't be longer than 60 while I was told by a few specialists that the maximum amount of symbols in title tag can reach up to 70.
Is this the data I should pay attention to or those standards vary from tool to tool and I need not care so much?
