How does Twitter affect SEO? I know the links are no follow, but Matt Cutts said in one of his videos that if Google can pick it up, it will. I assume he meant getting past logging in. With that said, I have noticed Google has picked up a few of my Google Plus posts in SERPs, but Twitter, almost never.
My concern is if repeating tweets is considered spam by the search engines. Suppose you repeat the same tweet every five days. Over a month`s time, that same tweet is tweeted about 6 times. But in a year, that same tweet is repeated 73 times. Beyond that, more.?
