What information do the crawlers send? They send keywords, a list of words and phrases that are repeated multiple times in a site’s code and content, or are located in certain important locations. Or both.

The information that results is folded into the search engine’s index, which is really just a massive directory of web pages, the keywords associated with each page, and how good the search engine thinks each page’s content is, relative to the other pages indexed for those search terms.

Which means: If your site isn’t indexed for certain keywords – “discount shoes, “ for instance – it won’t appear in the results page when a surfer searches for discount shoes.

It goes without saying that this is unfortunate outcome for shoe store owners.

So how do you get indexed? It’s really not difficult. The short answer is that you make sure the keywords you want a given page to get indexed for appear in certain important places on the page and in the HTML code.

These places are: The URL (or web address), the meta description, the title tag, in H1 headlines, the body of the web page’s text, in the filenames of images, and in an image’s alt attribute.

It sounds more complicated than it is, believe me. And in our next installment, we’ll define each of the phrases above, and discuss the benefits that each keyword location brings to your SEO efforts, and which have the most impact.

The last question – which has the most impact – is very important. Why? Because it is often difficult to include keywords in each of the above locations without diminishing the readability, or user-friendliness, of the webpage.

And since the single most important factor in search engine optimization is that good, user-friendly content is the most important component of SEO (Content Is King!), it makes sense to sacrifice some keyword positioning when creating good content requires it.

We’ll talk next time for about how to get your keywords where they need to be, and dispel some common myths about how keywords can impact your SEO – and how they can’t.
