The Web Page Content Score (WPCS)
To arrive at the WPCS*, a search engine will be examining the prominence and density of many different areas. In order to perform search engine optimisation (or SEO) to a web page, it is important to understand which areas need your attention. Here is a breakdown of each focus area:

Page Title:
This is the text displayed in the very top bar of your web browser. Page titles will also appear as the title in the search results on search engines. Page titles receive a lot of visibility before and after a person visits your site. Due to their high visibility, they are regarded as a very important variable in the calculation of your WPCS.

File Names:
File names are the names that follow the "/" after your domain name in the Address bar of your browser. File names are usually very short descriptions of a web page (e.g. contact-us.html probably contains the contact information for the web site). As file name size is limited, keywords** that are used in this area are deemed to be important. Search engines will consider the file name of the page being assessed, as well as the file names that are linked to, from the page being assessed.

Headings:
Headings use a special type of format called the tag. Applying this tag to text will bold and enlarge the text. Headings are important because they are summarising content on the page. The keywords2 within the heading will therefore carry more weight in the calculation of the WPCS than standard text.

Link Text:
When you click on a link to visit another page, the text that you have clicked on is referred to as the link text (unless you have clicked an image, in which there is no link text - not good for SEO!). This is probably the most important area of a page when the WPCS is being calculated. Search engines like Google have based their entire search algorithms on how web pages link to each other. The prominence (i.e. position and text format) and keywords2 used in your link navigation is very important.

Body Text:
The body text refers to the main content visible on your web page. Search engines will be assessing the total amount of content as well as the density of the keywords** within the body text. It is ideal to keep pages within the range of 200-500 words. If you have pages that exceed 500 words, try and break them into multiple pages.

Alt Tag Text:
Alt Tag text plays an important role in usability. Alt tags will display the text for images, which is useful if a user has images turned off in their browser. Alt tags have minimal importance in the calculation of the WPCS as they are invisible to the user most of the time.

Meta Description:
The Meta Description appears in the 'Head' section of the source code for a web page. This description is not visible when viewing a web page in a browser; however it will be used by search engines like Google for descriptions in their search results (see Figure 2 - if the Meta Description is available (and contains keywords**) Google will place the description under the 'Link Title'). Meta Keywords: Like the Meta Description, Meta Keywords also appear in the 'Head' section of the source code for a web page. It is dubious as to whether Meta Keywords are considered by the major search engines anymore. However, it is good to include them just in case. It's also possible that smaller search engines are still placing a fair amount of weight on this area of the page.

Once you have identified these areas of the page, you are ready to begin optimising the page. Good SEO is all about balance; too many keywords in any of these areas can lead to penalties. As a minimum, it is good to insert one occurrence of each keyword you are targeting into these areas. Sometimes you may encounter a strong conflict with your design. It is important not to forget that search engine positioning is one part of success for your site. Once your visitor arrives, you need to capture with your design and content. Ideally, it is good to consult an SEO expert before constructing a web site. That way you will avoid design conflicts and ensure that your web site has the best possible chance of success.

Quick Google Tip for Better PageRank:
Google's PageRank score is all about the perceived quality of a web page. A very easy way to increase your PageRank is to align your Page Titles, Link Text and File Names on your web site. Google sees this as good usability and will reward you. For example, if you have a 'Contact Us' web page, then it would be good to use a Page Title 'Contact Us', link to the web page from other pages using the link text 'Contact Us' and then name the page file 'contact-us.htm'.

* The abbreviation WPCS has been created solely for this series and is not a commonly used term in the SEO world.
** A keyword is any word entered into a search box on a search engine. For example if you visited Google.com and typed "leather boots" into the search box, both "leather" and "boots" would be the keywords used for your search.
