seo software.................................?

[Claud Bergman]

SEO software that will magically promote your website all by itself doesn't exist.
First off you need a plan for how you're going to improve your site's positions in search engines (Bing, Yahoo, Google or any other ones you may be targeting).
Then, depending on your strategy, you need to choose your software.

*As a rule, you would need an app that can detect crawlability problems on the site and identify duplicate content.
For these purposes, you can use w3c validator, for example.

*Then, it's also good to have an SEO tool that can tell you what backlinks your competitors have.
This will give you an idea of how many and what quality backlinks you need to rank higher than them.
Besides, it may help you find good websites, directories, blogs, etc. to get backlinks from.
I use SEO Spyglass for these purposes, but there quite a few other backlink checkers in the market.

*Then, depending on how many keywords you're optimizing for, you may also need a keyword tracker. It's a software tool that tracks search engine rankings of your website for the keywords you provide.
But if you only have a couple of keywords, you can simply check where you rank by hand.

Hope this helps.
