Hello, is this okay? After a week still my article with backlink to my money site is not index in google. This articles have 500 word. The article with backlink is unique and written by myself. All other article in my site are filler article that I take from expired domain and that expired articles was indexed in about 24 hours on google. So why it doesn't want to index my backlink? Could it be that I used the main keyword of the article to link my money site? I mean: In the article the main keyward is (for example) dog and I repeat this word 2%. But one keyword dog have the backlink to a dog site. Could it be this the problem?
