Okay, I’m calling it: if you’re using guest blogging as a way to gain links in 2014, you should probably stop. Why? Because over time it’s become a more and more spammy practice, and if you’re doing a lot of guest blogging then you’re hanging out with really bad company. Back in the day, guest blogging used to be a respectable thing, much like getting a coveted, respected author to write the introduction of your book. It’s not that way any more. Here’s an example unsolicited, spam email that I recently received:
What is Google's view on guest blogging for links?
Does Google take action on spammy guest blogging activities?
How can I guest blog without it appearing as if I paid for links?
