Can anyone tell me social sites where I have sent my blog URL for fast indexing and traffic?
No such thing as fast traffic. If your content isn't good, people won't read it. If your marketing isn't good, people won't see it. It's pretty simple.The social platforms to use however are totally dependent on your niche.
The best and effective way for this is to improve the quality of your content firstly, and then finding niche relevant platforms to market your content. Traffic will be automatically driven if your content is of superior quality.
