Google indexing doubt

I have blogspot blog. At first it has indexed in google. When i type site name google shows at first page. Later I have added popup ads to my site. Then my site not showing in google search. What is the reason. I have seen some sites are indexed by google even they contain popads.

 

I believe the popup has nothing to do with the indexation.

 

Yeah, maybe the issue is with your content. Do you write unique fresh articles, or outsource them or do you just grab PLR's across the web? Google might have deindexed your site if you were penalized.

 

Google has change the way indexing, we add or delete any thing on our site so some time we loss google indexing,

 

Maybe it is about your blog content...do your blog have unique content?
I don't think pop up cause problem to your site.....

 

What is your blog URL?
Maybe you are in sandbox

 

Thanks for replies
I think the problem is unique content I have copy pasted some content from other sites.

 

Youy are definetly in sandbox or some kind of penality because its not ok just to paste others content.

 

@krishatnet, if you are copy/pasting the articles, try to spin them and paste, including the title.

 

may be their is some relation with your content. so try to create some unique and quality content for your blog
