Still can't write title tags - what am i missing?

no tool needed. export the urls from the sitemap into a sheet, then in search console look at which query each page already gets impressions for, that's your primary phrase per page. title formula: that phrase near the front, a few words saying what the page is, brand at the end, keep it around 55 to 60 characters so it doesn't get cut. google rewrites some titles anyway, don't fight it. expect movement two to six weeks after recrawl, request indexing on the important ones to speed that up.
