Hello, My site zemtv.com , Was among in good ranking of google search result.. The new posts were used to indexed by google in 10 - 15 mins and were always found in top three results .. but from past 4 -5 days, google is indexing my posts but the results are not shown. does this mean that google has black listed my site ? ... Please help me getting out of this issue ..
No, I don't think that google has black listed you. The search results vary time to time. Don't worry, keep on posting quality content and keep submitting ur updated site map.
my previous posts which were at top position are still at top, basically i run a wordpress and post videos which very less text content ... is it dangerous ?
dangerous not, but more content = better... if you will have less content - search engine cant determine relevant serch terms for those pages, so you will get worse rankings - thats all that can happen
Yes, do not rely simply on video, give out a word or two. Not only good for search, also good for user experience, people will make their minds whether they want to watch a video clip or not. Will result in less bounce with time !
