It is hard to believe the all too short northern summer is almost over. In less than two weeks, kids will be going back to school and commercial webmasters will be gearing up for the autumn and winter sales seasons. This is as good a time as any, perhaps better than most, to cover SEO 101, the basic techniques that form the foundation to an advanced SEO or SEM campaign.
For the purposes of brevity this piece starts with a few assumptions. The first assumption is a single, small business site is being worked on. The second assumption is that the site in question is written using a fairly standard mark-up language such as HTML or PHP. The last assumption is that some form of keyword research and determination has already taken place and the webmaster is confident in the selection of keyword targets.
Believe it or not, basic SEO is all about common sense and simplicity. The purpose of search engine optimization is to make a website as search engine friendly as possible. It’s really not that difficult. Basic SEO doesn’t require specialized knowledge of algorithms, programming and taxonomy but it does require a basic understanding of how search engines work. There are two aspects of search engines to consider before jumping in. The first is how spiders work. The second is how search engines figure out what documents relate to which keywords and phrases.
In the simplest terms, search engines collect data about a unique website by sending an electronic spider to visit the site and copy its content which is stored in the search engine’s database. Generally known as ‘bots’, these spiders are designed to follow links from one document to the next. As they copy and assimilate content from one document, they record links and send other bots to make copies of content on those linked documents. This process continues ad infinitum. By sending out spiders and collecting information 24/7, the major search engines have established databases that measure their size in the tens of billions. Every day, both Yahoo and Google claim to spider as much data as is contained in the US Library of Congress (approx. 150million items).
Knowing the spiders and how they read information on a site is the technical end of basic SEO. Spiders are designed to read site content like you and I read a newspaper. Starting in the top left hand corner, a spider will read site content line by line from left to right. If columns are used (as they are in most sites), spiders will follow the left hand column to its conclusion before moving to central and right hand columns. If a spider encounters a link it can follow, it will record that link and send another bot to copy and record data found on the document the link leads to. The spider will proceed through the site until it records everything it can possible find there.
As spiders follow links and record everything in their paths, one can safely assume that if a link to a site exists, a spider will find that site. Webmasters and SEOs no longer need to manually or electronically submit their sites to the major search engines. The search spiders are perfectly capable of finding them on their own, provided a link to that site exists somewhere on the web. Google and Yahoo both have an uncanny ability to judge the topic or theme of documents they are examining, and use that ability to judge the topical relationship of documents that are linked together. The most valuable incoming links (and the only ones worth perusing), come from sites that share topical themes.
Once a search spider finds your site, helping it get around is the first priority. One of the most important basic SEO tips is to provide clear paths for spiders to follow from “point A” to “point Z” in your website. This is best accomplished by providing easy to follow text links directed to the most important pages in the site at the bottom of each document. One of these text links should lead to a text-based sitemap, which lists and provides a text link every document in the site. The sitemap can be the most basic page in the site as its purpose is more to direct spiders than help lost site visitors though designers should keep site visitors in mind when creating the sitemap. Here is an example of th
