The Title Tag
The Title is the MOST important aspect of on-page search engine optimization. Generally you should make sure to use at least one variation of your keyword here. The Title of the page is what shows up in the search engine results and will help bring users to your page.
In Webs.com, the contents of the title tag is the site title plus the page name..
The Body Text
Focus on using your keyword in the body text in bold. Bold tells a search engine that this is strongly emphasized and important text.
The first sentence in the body text and the first words used per sentence
These are the most important ones for advanced on-page search engine optimization necessities. Make that sentence humanly readable and search-engine readable.
The URL and File Names
The subdirectory folder and file name of the page should be search engine optimized (i.e. http://polymericmaterials.sites.acs.org/membership/registration.html would fetch a high ranking for those looking for membership in a polymeric materials groups, especially with many highly authoritative, relevant, deep in-bound links coming from other sites.
Header text (H1 and H2)
The header text (H1, H2, H3, etc.) show the search engine the main subjects and Table of Contents for the content to be indexed. Make these keyword friendly and reflective of your page’s title tag and content.
Same Site Link Texts
The links connecting the pages of your site together must have your targeted keyword terms in them as well as all links throughout the site — even though it seems excessive, having variations to your targeted keywords would also help when linking out to other pages within your site.
Same-Site Link URLs
Not only should you be using your keywords to describe pages within your site, those URLs you link to must have SEO URLs, eg: http://prof.sites.acs.org/membership/renewing.html.
Outbound Link Text
Use good keywords in the text you use to link to another site. If you’re an association web site and are linking to continuing education opportunities (online courses in this instance), you would use “Find the best sources for online continuing education Chemistry courses - American Chemical Society Webcast Courses.
Your images should be described via ALT Tags with the keywords you are optimizing for (we don’t think this can be done on Webs.com) If your image is hosted on your web-host, the file name of the images should also be SEO’d — If you have an image about polar bears have it be polar-bear.jpg in your images folder.
8% is excellent and doesn’t seem spammy, if you have a 500 word article, then 40 of those words should have variances of the search term you are targeting, if this seems excessive, lower the keyword density down to 5% and you will only need to add 25 variances/instances of your keyword. And that’s just a start… (Keyword prominence is big, but not worth a discussion).
Web search engines only pay attention to two pieces of metadata: Title and Meta Description. Google uses description copy to market your site in its results. Use this text to concisely and readably tell the user what the page is about. Webs.com allows you to enter a meta description for the entire site which appears on each page.
