Website designers should not always concern themselves with making a website look nice. They much also employ website development that includes crafting a search engine website.

Yes, website design concepts must also include those tactics needed for allowing website spiders to "crawl" the site (deep scan for keywords, links, etc) and then boost the search engine rankings as a result.

There are certain basic procedures that need to be employed in order to make a website search engine friendly. Far too often, however, people will assume that link building is the only necessary item for boosting search engine rankings.

In all honesty, simply building and trading links can(and will) boost search engine rankings. However, relying exclusively on link building as part of your website marketing plan is a limited one. After all, your website is following a "single minded" approach to search engine optimization and this can create problems down the road.

After all, what happens when a link is removed or deleted? Search engine rankings take a hit! This is why it is also important to weave in search engine friendly page tactics when exploring web development.

Obviously, the website design must carefully employ the use of keywords. Keywords are those terms people type into a search engine in order to locate websites related to the subject.

If your website deals with Christmas trees, then the homepage of the website should include a number of terms associated with Christmas trees and Christmas related terms. If the site is sparse on these terms then the website designers will need to add them.

This, however, does not mean that website design should be bloated and overloaded with keywords. Such tactics are self defeating because they can lead to a poorly composed website. Also, many search engines frown upon keyword overloading and may rank your site poorly as a result.

Here is a brilliant web development tactic that many websites overlook. All it involves is simply adding a few links to the bottom of the website. Let's say your website centers on baseball. If you add five (small font) links to the bottom of the page that are popular baseball related websites you might pick up ancillary traffic.

For example, you can add links to MLB's homepage, the Hall of Fame's website and you could even link to Topps' baseball cards' website. This way, those searching for those sites may end up stumbling on your particular baseball site. Some may think this tactic is dubious, but it draws in a surprising amount of traffic if employed properly.
