I had one of my websites indexed in 1 day and ranked in 3 days (for a keyword with no any searches though) without any backlinks. And now I have another new website that was indexed in 4 days, but it is still not ranked yet after one week since I started this website. The keyword is low competition. I'm worried if I have not over optimized this website. I have a 320 words article on this page of my website and I have mentioned my keyword 1 time in the article and also in the title of the article (it is a WordPress blog). What would mean an over optimized website?
