Html codes?

As far as I know frames are indeed the main thing you should avoid. Also Flash, Dynamic URLs and JS navigation should be avoided.

Take a look here:

I have downloaded some free trial SEO software, just a few days ago, so have not used it yet! But, I'm really learning a lot for the free software. If they put this into an ebook, I'm sure they could sell quite a few copies!

*Also, on first link below is a website that offers about ten website and blog awards. They are FREE & even provide a link back to your site! Plus, they show the visitors that your site is a noch above the rest. Keep in mind, to get the award you have to have good info on your site and not just junk w/jumping graphics and tons of AdWords!

So, bottom line, GET THEIR FREE TRIAL SOFTWARE and even if you do NOT do anything else...you'll learn a great deal about SEO from people who make their livelihood DOING IT!

Frames are very problematic. search engines cant read them. They read only the first frame and don't continue to the rest.

Flash pages - if they are built only as flash and don't have extra content can cause a problem.  Flash elements on regular pages are OK.

dynamic links - java, ajax etc. search engines can't follow them and cant index the pages they refer to.

There are many more elements, but the best way to find out how a search engine sees your site is to use a search engine spider simulator. There are many free ones on the net (some of them come as toolbars). 

Here is a link to one of them:
