Welcome to the Q&A Forum

Hi, As you can probably see from the title, a massive rant is coming up. I must admit I no longer understand SEO and I just wanted to see if you have any ideas what might be wrong. So, I read this blog post on MOZ https://moz.com/blog/influence-googles-ranking-factor - where the chap is improving ranking of content that is already ranking reasonably well. I've got two bits of news for you. The good news is - yes, you can change your articles' ranking in an afternoon. Bad news - your articles drop out of Top 100. I'll give you a bit more details hoping you can spot what's wrong. Disclaimer - I'm not calling out BS, I'm sure the blogger is a genuine person and he's probably has had success implementing this. The site is in a narrow but popular ecommerce niche where the Top 20 results are taken by various retailers who have simply copy/pasted product descriptions from the manufacturer's websites. The link profile strength is varied and I'm not making this up. The Top 20 sites range from DA:4 to DA:56. When I saw this I said to myself, it should be fairly easy to rank because surely the backlinks ranking factor weight is not as heavy in this niche as it is in other niches. My site is DA:18 which is much better than DA:4. So, even if I make my pages tiny tiny bit better than this DA:4 site, I should outrank it, right? Well, I managed to outrank it with really crap content. So, I got to rank two high-traffic keywords in #8 or #9 with very little effort. And I wish I stayed there because what followed just completely ruined my rankings. I won't repeat what was written in the blog. If you're interested, go and read it, but I used it as a blueprint and bingo, indeed Google changed my ranking in just a couple of hours. Wait, I lost more than 90 positions!!!! I'm now outside Top100. Now even irrelevant sites in Chinese and Russian are in front of me. They don't even sell the products. No, they're even in different niches altogether but they still outrank me. I now know exactly what Alice in Wonderland felt like. I want out please!!!!
