Anyways, in February, 2 of my pages which ranked on first page dropped big time, like on 10th page. And now that I looked at it, I noticed the actual pages that ranked for those keywords are NOT ranking for those keywords anymore but rather some other pages of my website are ranking for those keywords. So it makes sense it's so far high up, because those random pages are not optimized for those keywords.
So my question would be, why do you think those 2 pages disappeared from the rankings? They are still indexed by Google so they're not banned or deindexed. Do you think algorithm just didn't like them and manually de-ranked or penalized them? The two pages do not have any spammy external backlinks pointed to them, although there are some internal links pointing to them from my articles. But then again that's the case with most pages on my website.
What do you guys think is the most likely problem and the solution?
