The following is a brief list of items web designers, web developers, and web optimizers should try to avoid when performing SEO on a website: 1) Splash pages: Not only splash pages are bad for SEO, it’s also high on the usability NO list. Take this one step further, sometimes these pages are 100% flash, making it impossible for search engines to spider the page, and follow the link. 2) Flash Menus that can’t be spidered: Many designers make this mistake by using Flash menus such as those fade-in/out and animated menus. Yep, sometimes they look the business, but they can’t be seen by the search engines; and thus the links in the Flash menu will not be followed. 3) Image and Flash Content: Dont embed important content (such as target keywords) in Flash and images 4) Ajax heavy sites Dont try to impress too much, specifically by deploying massive Ajax features (particularly for navigation purposes), as this is a big SEO mistake. 5) Unfriendly URLs: Most blog or CMS platforms have a friendly URL feature built-in, however, not every blogger is taking advantage of this. Friendly URL’s are good for both your human audience and the search engines. The URL is also an important spot where your keywords should appear.

You have a good post here. All SEO mistakes concern On-page Optimization of SEO. May I also add that there are also SEO mistakes that some people applies in their link building methods, which falls under Off-page Optimization of SEO. How about have a part 2 on this-- something that talks about Off-page Optimization Mistakes.
