Search Engine Zombie is a simple little tool that let’s you inspect files and check for very, very, very, basic SEO guidelines on your page.
It checks existence of Title tags, Meta tags, Header tags, looks for images without alt attributes and links without title attributes.
It does some basic checking like verifying that your title is within the 72 character range and that your description also does not exceed the limit.
It has a nifty little word counter that counts occurrences of words that are longer than 2 characters long too, helping you, if you want, to choose the most frequently used words in your document.
At this stage, it is very, very basic. It does not do much more than what I have described, yet, it does com in handy for very basic SEO checking of a page.
