One of the nicest features of Wordpress web pages are the many plugins available to help with Search Engine Optimisation. These plugins allow you to easily customize URLs, titles, and descriptions. This can be a great help in avoiding duplicate content or simply matching titles to addresses for relevence.
However these plugins should be used carefully, for one can very easily over-optimise and incur an SEO penalty.
A good rule of thumb when using Wordpress to create pages is to limit the exposure of the main keyterm you are optimising for to just one occurrence to approximately every 150 words of other content. Bear in mind that overall keyword density must also be checked. If your keyword phrase is "Cheap Office Furniture" and you use the word Cheap 800 times, you will likely disqualify the whole page from ranking.
In fact you will find that page ranking in reverse, meaning it will rank for ridiculous long tail keywords of little or no value. Google has a tendency to default to the remaining words after the keyword stuffed words are filtered from the page's relevance.
When putting together SEO planned pages on Wordpress sites we must watch out for accidental redundant use of our keyterms in titles, category listings, recent posts etc. Another place to watch is in picture titles and internal links, as all of these represent places where one can easily repeat the same words over and over. Use the highlight function built into your web browser to locate all of the uses of your keyterm words both separately and combined.
