So first, the usual "the old days were better"... In 2009 - 2012 I build several niche sites in fitnes & diet, low comp authority sites in sports & leissure & diet, and some blogs.. Till 2013, you could just rank with good content. Guys & girls, please spare me the usual "make more free shit to get better rankings" stuff.. I been through that. It is not 2010 any more and even in .de, it doesnt work anymore fore years.. So, in 2013- I not only got into my first university year at age 29, i also partied hard and - yeah, you know the rest with women... So close to 3 years, I did nothing, and the mediocre german competitoin crushed my good sites with great content with their newer sites, often ranked with some crappy backlinks and bad content.. (so much for the usual Google Cutts More Free Fresh Content Bullshit talk) Ok. I am pissed. cause University did not work, partying and girls also, and I stopped drinking - got me into too much trouble too. Still have all my youtube projects, that produce some nice money, but I want to get my blogs back 2 date. Again: And NO, we will not go into that "make more free content" shit discussion. please. spare me that. THE POINT IS: How do I find out, which site is worth to improve with content? Invest with PBN Links & Social Signals & Onpage SEO? I somehow got lost in all this and could simply need some very simple silly advice.. I used to do G analytics and just check keywords, and put them into ahrefs - BUT t hat doesnt work anymore !!! Cause G doesnt show me the ranking keywords..... From the past, I know which site could produce $$$. But I am somehow lost, to find out, which site is worth time to improve. Eg. check competiton or ranking. Like I said, even some simple ideads could help me now.. The thing is, it is around 25 blogs / sites / domains, that I need to check... That is why I ask.
