SEO Mistakes: read the fine print
I still hear from people who get confused by solicitations in the mail. Here’s an example one:
At first glance, this semi-official looking letter seems to require bill payment for some sort of “annual website search engine listing.” But if you read the fine print at the bottom, you’ll see:
This is not a bill. This is a solicitation. You are under no obligation to pay the amount stated above unless you accept this offer.
In other words, feel free to throw this letter in the trash. If you want to submit a url to Google, there are at least a couple ways to do it, for free:
- Google offers a free “add url” form where you can submit your domain name.
- You can make a Sitemap (a list of urls for your site) and submit it for free as well. Start here. There’s a lot of other free, useful tools from Google there too. 
When you get a letter like this in the mail, whether it’s about your web site or your domain name, read the fine print carefully.
