Why is Twitter Good for #SEO?
edited for 2017
It’s simple. Tweeting enables on site SEO to work because when you tweet a URL googlebot(and many other bots) will notice. There have been occasions when I’ve tweeted a new post and less than a minute later found the post on page 1 of Google. There are other social bookmarking sites and micro-blogs feeding the info companies, but the number of bots interested in Twitter links makes it the top traffic cop I’ve observed. Even better than Digg in it’s heyday.
I read a very popular blog once and in it the words Twitter, SEO, and waste of time were all mentioned in the same sentence. I can speak from personal experience when I say that twitter is a very good tool if used appropriately. Always tweet your content considering humans and web crawlers. Tweet randomly and only one or 2 at a time. After the second or third tweet over an hour the bot traffic drops down to nearly 0. One tweet every few hours seems good for indexing results.
edit: and now with Google plugged into the firehose I don’t see Twitter becoming less important to SEO any time soon.
