I have setup my website for 4 years. Over the last 12 months, my visitor hits have been reducing gradually. What really shock me was the decrease of hits from Google. Every month, it decreases by 65% (see below). I have been updating my website regularly. Nothing is wrong with the contents or the server. I desperately need to know why the hits from Google drop so fast.

Top 10 hits for the last few months.

Have you tested the search terms for which you've been successful in the past to see how you rank? Is there a chance your site was reported for abuse for some reason (hidden text, spamming, etc.)?

Can you post a URL to your site? Maybe someone will be able to spot a red flag on it or something. I don't know if Google attempts to contact site owners when they ban them from indexing, nor do I know whether the site is completely removed or just loses rank when it's flagged. But this might be something you'll need to take up with Google, once you have more info.

I have tried searching. I found some 300 pages of my site in Google. Everything seems to be in Google and searchable. But the rate just keeps dropping.
