Hi I have the same situation with two of my websites. Both of them have a TOP 1 in Google for one keyword for example:"account bonuses" and both of them are under 100 now for other main keyword for example: "account" but they were on Top 10 before. Why ? Is anyone has similar situation ? What should I do now ?
it refers that your site's link and contents are deleted/ de indexed. that's why your rank is fallen.
Are the keywords you are talking about pointing to a single page only? Homepage for example. If not, could be that the links pointing to the other pages were gone or other websites are working better against your seo campaign.
I agree with danasurvey. Focus and continue on working on your SEO. You seem to be doing fine with one of your keywords, you can get the other there was well. Do it naturally and remember, patience is a virtue.
Yes thanks for advices but I was in TOP 10 with my main Keyword which point to Homepage, now I'm on the first position only for one keyword which also point to Homepage, so this is some sandbox and the same situation for 2 sites, so maybe somenone has similar situation.
Competition surely has something to do with it, your site probably outranked by others. And with recent Google changes, you need to make reliable new changes and information to get the rankings back.
