Alright, so, basically I have two sites that have very weird dancings. One went from serp 39 to serp 80 yesterday, today it's back. But I have two more sites. Site 1: Stats here: Graph here: This is a pretty new site, it's like 14 days old, but it's basically low competition, as you can see, 2 days ago it had serp 24 for the main keyword, yesterday just jumped to serp 70, today when I woke up, serp 120. Few hours ago, it had no serps ... but 30 minutes ago came back to serp 120. The hell is going on? I didn't spam the website, I had maximum 40-50 backlinks pointing to my website. The thing is, that I've updated the meta keywords (just found out some more keywords), maybe that's the problem? For example, in the beginning, for this site, I had only 3 meta keywords, now I have around 8. Site 2: This site is around 1 month and 10 days old, this started to climb very well since 11 october. As you can see, on 23 it had the best serp, now it's on 50. Same thing here, updated the meta keywords ... And forgot to mention, for both sites I was keep updating them with content, 1 day on, 1 day off. Then after 18 october I stopped posting new content on the website, until yesterday. Maybe that's it too? What do you guys think? Thanks!
