I am noticing that google remove my website and its all sub domains and every thing from SERP. But the website is indexed and also gets crawl meanwhile. This happened for 4 times since last 6 months, If anybody there can tell me what is the reason for that...... i am too confused.. Please advice.
if the domain name is new den this happens to need to continuouslt keep on optimising for 1 year. if the domain name is old n still this is happening try changing meta and concentrate on on page optimisation coz it might help you.
Dude google don't care about such queries. If you are seo you have to think and guess what is wrong there with your website.
