Hi guys, I have a question. My website is 2 years old. And it has been changed the url one time for better serp. But when I change the url with keyword in it. I found till now it has not been indexed by google for months. I don't know why, and I keep building profile links, exchange links, social bookmark, till now, still unindexed. What should I do, is there any way that I can do to let google index? please help.
