I have a website and it was ranked 2nd in keywords for about 2 months, it suddenly dropped to page 9 even though I didn't make any changes and it has been on page 9 for more than a month and it doesn't come back up. When I check the backlink side, there is no attack. I didn't do/haven't done any hacklink etc. I didn't receive any spam etc. warnings. What could be the problem? How can I solve it? Is there anyone who can provide paid/free support?
