Careful Keyword Selection is the Heart of the SEO Plan
Site owners who are on top of their SEO game have a list of top-priority keywords that they use on their site, with reasonable repetition, in strategic places. If a site’s focus or positioning changes new keywords are needed. Another important thing to note is that the most important keywords should be listed first where possible. The position is especially important on page titles (shown in the address bar of the browser) and the description meta-tag (shown in the Google search listing). The keywords in your meta-tags should be included on your page ideally 2 to 3 times (with variation) to achieve a good keyword density relationship. By relationship here I am referring to having the targeted keyword/s in the page title, the heading tags, the text copy, in page links, file names, and image names.
It is also important to know that the text content placed in the top 1/3 of the page (above the fold) will be indexed more frequently and fully than content below. In this regard be wary of using large slideshow at the top of the page without a text overlay or Banner Ads at the top of your pages since they provide less room for important text and banner ads may also irritate your visitors. Finally, it is a good practice to keep an SEO journal wherein you track when and where you submitted your website and every major site that links to you, and then periodically check to see if your site has been indexed, and its ranking per likely search queries. It will typically take anywhere from a couple of weeks to a couple of months to get listed, though in many cases your site will be crawled and indexed automatically.
