Welcome to the Q&A Forum

Hi Peter! Keyword Difficulty takes into account the Page Authority (PA) and Domain Authority (DA) scores of the results ranking on the first page of Google for the given query, as well as modifying intelligently for projected click-through-rate of a given page (putting more weight on higher-ranking, more visible pages and less on lower-ranking, less visible pages). The formula also accounts for newer pages on powerful domains that may have DA scores but have not yet been assigned PA values. I hope that provides some clarification!

The .co.uk domain is already geo-targeted to the UK, so unless you are targeting other countries/languages

Glad you're seeing the site back in the rankings. I would definitely keep digging, though. A 14-month disappearance is not something you want to chalk up to an error, because you could easily relapse days or weeks from now. In other words, it's good news, but don't let your guard down.

Hi there, I see what you're trying to do, and I think I understand it. You're attempting to conserve your link equity and flow it only to the most important pages, or what we use to call "pagerank sculpting." The good news is you don't really need to worry about it. These days, adding nofollow to your links doesn't really increase the equity flowing through the followed links. And in fact, you could be shooting yourself in the proverbial foot by denying equity passing links to your lower product pages. Best time to use nofollow for internal pages is typically to increase crawling efficiency, or to prevent bots from visiting pages you don't want indexed anyway. Attempting to scuplt link equity in this way could cause lots of unintended negative consequences and my advice would be in most cases to let your link equity flow freely throughout your site in a way that was natural to both humans and bots alike. Best of luck!

Hello elf925, As Leonie said while it may be identified as duplicate content, our duplicate checker just scans for matching code. While SERPs may have a different way of analyzing whether content is duplicate or not we will flag it to be better safe than sorry. If 90%+ of the HTML matches we will flag it as a duplicate in our system to alert you. A search engine may not recognize this as duplicate  content but we like you to be aware just in case.
