So you submit your directory to another directory. So someone goes to a directory and clicks on a link to your directory, and then clicks on a link in your directory to go to another website. What a complete waste of time and energy that is, and a really good way to annoy your potential customers.
What I was trying to get across in my previous post is that successful SEO isn't just about jumping through a series of prescribed hoops, ticking a set of Google-approved boxes. That's too easy, which is why it doesn't work. Google isn't remotely interested in helping sites where the developer has put a lot of effort into improving the site's ranking. What they want is to help sites that are genuinely useful to real people. And that's where a generic list of meaningless buzzwords and mindless automated processes are totally useless. What you really need is some kind of business strategy first, and only when you've got that is it worth moving into the murky waters of SEO.
