Myth One: Search Engines don't "see" Images
While this is correct that the actual image itself can't be seen by search engines, applying appropriate tags to the image can benefit your image search capabilities and on-page optimization efforts. While not a huge benefit, Alt Text and Image Filenames does make a difference and should be included in your SEO strategy.
Myth Two: An SEO Can 'Fix' Your Website after it's Built
The simple fact is, if your website is not designed and built around search engine optimization the first time around, it will be more difficult and more expensive to optimize your website for search engines after it's designed. Most web designers don't know what's important for SEO unless they've researched it on their own and can seriously screw up a site's optimization. Optimizing a site that hasn't seen the hand of an SEO can need some serious changes including code changes, CSS changes, and a complete reworking of internal structure.
Myth Three: Google is the SEO God
While Google is very important, there are two other major search engines out there that have their own set of rules to abide by. If Google said it, it may not necessarily work on other search engines. Take all the rules into account, test a bit and see which one works best. Google may not be the end all be all of SEO techniques.
Myth Four: No-Follow Links Don't Count
Actually, Google, Bing and Yahoo all look upon an unbalanced Do-Follow/No-Follow links as spam. If you've got too many Do-follow links, the Search Engines may actually punish you rather than give you rankings. Try to keep a healthy balance of no-follow/do-follow links to keep your link profile healthy and natural.
Myth Five: Internal Linking Doesn't Matter
The main issue we find when optimizing a client's website is that their previous SEO Firm hasn't paid attention to internal page authority techniques. Internal linking is one of those techniques. Linking to your interior pages via the receiving page's keywords creates authority within the interior pages of your website. This can improve your interior page's PR Rank and even the search engine rankings of your interior pages. Not taking advantage of this can be severely detrimental to your website's on-page and overall website optimization.
