I just got TT v.4 and after importing one of my projects almost every page has 2-5 warnings on it. For example: "Your page has too many H1 tags" (only two -- the title of each blog post, and one H1 line near the top of the blog post that intros the content) "Your page title and H1 tags are the same" (Page title is expressed on the page with H1 tags, so I'm not sure exactly how to fix this... or why I'd want to. Is it hurting me?) "Your meta description is more than 157 characters" (Sometimes I want to end a sentence and it runs it to like 165. I understand it will get cut off, but does that matter to G?) "Your title tag is less than 39 characters" (This is for some internal pages with shorter, descriptive titles such as the name of the product I'm reviewing + the word "Review"...) "URL is more than 72 characters or contains more than 5 words" (I can fix this rather easily, though it's a tedious process, if I have to. The question is, should I?) Basically, I'm wondering how much weight I should put to warnings like this. Other than these things, my on-page SEO is quite good. The site is rather new, so I can't really tell if it's hurting me in the SERPS, since I'm nowhere important yet anyway. Should I go through and 'fix' all of these things, or is it minor enough to let pass?
