Hello, I know that it is important to have backlinks from facebook and twitter to gain exposure on my websites. However, I am wondering if I should create separate Twitter accounts for each of my websites. Does the backlink on the profile page of twitter make a huge difference cause you can only put one link. Or should I be okay just keeping one twitter account and Tweeting backlinks to different websites that I own?
The answer depends on what you are promoting. If you have multi accounts on Twitter, you will have difficult to manage them. If you want to brand your product or your site, you need to focus one account on Twitter. And also Facebook.
Yes you must create separate twitter accounts for each website you're promoting. That will help in creating a brand. RT tweets from your account for the extra perks.
It's best to create separate Twitters for different websites and brands. You can't constantly promote x to your y followers or they will unfollow.
you should use another account for another site only if there are in different niches. If both sites are in the same niche but promoting different products/services I think its ok to be promoted on the same account.
