Similar page result? On what?

Are you referring to your search score for your website on some search engines? That just shows how well the website contents match your search string.

The exact percentage of similarity of two pages after with a search engine may penalize you is not known, it varies from search engine to search engine, Your aim should be to keep your page similarity as LOW as possible

What are some good ways to market or advertise my website?

Where are you finding this information? How are you testing this similarity? And what two files are you comparing?

If you link all of your pages to each other, with the links at the tops,then the similarity is not much of a penalty.
