my website ranking top one on Google for years,
but my website home page is de-indexed by Google 2 days ago.
all the search results from google disppear.
I believe my website has been under some attack and the de-indexed is the hacking results.
I need to find someone to find out the causes of de-index by using google webmaster tool and website server log,
and get my home page re-index by Google.
and give me advice about how to prevent this happen again.
the hacker has been trying to knock my website down for years, therefore, I need ongoing web security service for my websites after the current problem is fixed.
my website is in a Linux shared hosting and my website ranking is normal in other search engine.
the person I am looking for must have experience in Google webmaster tool, website security and system admin.
