I am definitely a newbie in the SEO realm, but here are a couple of free SEO tools that I have stumble upon in the last few months:
- Trends from Google: Compare and contrast various keywords with this free utility. It doesn't tell you actual numbers, but you can pick one popular keyword as a constant and compare other keywords to it. Gives you a decent feeling for what you should be aiming at when it comes to keywords.
- Keyword Cloud Tool: Great way to visually find out what keywords are plentiful on your site. In fact, SEO Chat's home page is loaded with a number of other free tools that are worth a second look.
- Google Sitemap Generator: This is great site that will generate a XML sitemap file for free. There are a bunch of sites out there that say they will do this, but this one is the best one that I have found.
- Good Keywords V2: This is a fantastic app that you can download and run locally. It will analyze your pages and make good one word and two word keyword suggestions.
