Responsive Website lost their Ranking on Google?
 

Recently I have read the article on SEO regular update website that Google does not rank responsive design sites better than other separate site which configures
only for mobiles.Is it really true?

yes it is true... i have also read about it.

Google give rank both either the website is responsive nor it's mobile friendly as yet i analysis both are getting equal = result .

yes google provide ranking to both responsive and non responsive if you any article or any link to clear it out that that responsive site not work well

I haven't heard this information before.I always thought that google would consider the website to be responsive and also mobile friendly so that it could have better rankings.

Up dùm, chúc bạn may mắn..................

haven't read that but still believe content and backlinks plays a crucial role on how your site going to get indexed and rank and of course it should always be whitehat kind of optimation

Nowadays, responsive website too got affected by spammy contents...so google restrict those sites too from ranking

Design has nothing to do with SEO.
Has to do, with the visitor's/user's experience ONLY.....

Ranking drops are often caused by large changes to a website. When you've migrated a bunch of pages, rolled out a (responsive) redesign or reworked a lot of content you'll see big fluctuations in your rankings. This is natural, and should only worry you in ase your rankings don't come back to their previous state.
