Initially you’ll need to ensure that your home page, and others, has a keyword rich title (typically 8 words or less), and a short, keyword rich description. The “robots” tag is not used by Google anymore (neither is the “keywords” Meta-tag) but some of the lesser search engines still use it. If your page has the “robots” tag “content=”noindex” this tells them not to index the page, so be sure that’s not in place. WordPress and other CMS websites will include additional Meta-tags, but the three noted above are the important ones for site ranking.
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. This is especially important on page titles (browser) and the description Meta-tag. The keywords in your Meta-tags should be in evidence on your page if at all possible, ideally 2 to 3 times (more inclusions than this can get your site blacklisted for spamming!), and have a good 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 will be indexed more frequently and fully than content below. In this regard be wary of using Banner Ads at the top of your pages since they provide less room for text, and they may 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 then periodically check to see if your site has been indexed, and its ranking. 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.
