Here's an interesting one.
I've just set up a new website with an email signup form. I posted a question on this forum with a link to the website's URL.
Within 4 hours, this post became the top search return for the website's URL on Google! Which would be great free marketing, apart from the fact that I used the phrase "complaint from a subscriber" in the post.
I've removed the post, and I'm hoping it'll disappear from Google!
