Recently, this blogger has received requests to run guest posts. Clearly, marketers have read all the SEO literature, attended the webinars, gone to the conferences, and are ready to manufacture back links. I don't think this is possible.
None of the blogs I read, and I read a great many, have guest posts. This indicates to me that bloggers are not interested in running guest posts. There are online publications that consist entirely of marketer's donated work. I am not enthusiastic about these. I am also concerned that Google's new algorithm will punish promiscuous back links.
When SEO advice contradicts your experience of the web, trust your experience.
There is a way to drive traffic to your site, buy it. You can purchase online advertising at the news publication your prospects read. If you don't know what they read, ask them. Send out a survey. A survey is a great way to learn more about your customers and prospects. People like it when you ask for their opinion.
You could purchase a sponsored link on the homepage of their user group or trade association. That way you could get their attention in a way that builds community.
Or if cash flow is a problem, you could purchase a sponsored link at Reddit for as little as $20.
Advertising is SEO neutral, but it drives traffic to your site and generates leads, and that was the object wasn't it?
