What is the Best Free Onpage SEO Checker Tool?

This post is more a question than an answer. We all know that even though onpage factors are only a small part of optimizing your website for the search engines it still is one of the only things that we fully control. Incoming links are something that we can influence but never fully control.

There are a lot of things that go into onpage SEO but the more obvious once are Title tags, Meta description, Keywords tags, H1 and H2 and of course optimizing the internal link structure of the site.

But lets assume that you can’t remember all factors that are worth optimizing or maybe you’ve just added a new wordpress theme to your blog and you didn’t think of checking whether it was optimized or not. It just looked good. So now you want to check that everything is okay but what is the fastest way to do it?

I’m positive that there are free online tools available online that will help check these onpage factors for you with a few clicks but for some reason I simply couldn’t find them when I tried searching for them.

One of the tools I’ve been using is the Stompernet Siteseer tool (you have to enter your name and email to access the tool). The tool does a great job explaining why you need to do each of the little details but once you’ve read it (and watched the video) you don’t want to see it every single time. Secondly you’ll have to wait for them to send you the report by email. Its great if you’re a total beginner but not if you know a little about SEO.

My question to you is whether you know of a free tool for checking these onpage factors fast? If you know of a free tool that will also let you check these factors on the top 10 Google ranking sites for specific keywords that would be beneficial as well. I know that these tools exist if you pay for them (I have a few of them myself) but I’m looking for a free tool that anyone can use.

So if you know of one (or more) please share it with us. Thanks.
