Search engines bring more than 80 percent of the traffic for small to medium websites. This tells exactly how important it is for small and medium websites to optimize their web structure and pages for search engines. Optimization of your website for search engine includes many aspects: website content, keywords, URL, meta-tag, back links, etc. Let's explain it one by one.
Select the right keywords. You can pay a visit to your competitors' websites (only those with top-ranked search engine placements). Through analyzing their web contents and meta tags, you can easily find out the keywords they are using. Overture keywords selection tool can also provide you valuable information. Open your favorite browser, enter http://inventory.overture.com/d/searchinventory/suggestion/, type in the search box your keywords or phrases and see how many times they were searched last month. Select those with high search frequency. Google also has a similar keyword selection tool at https://adwords.google.com/select/KeywordSandbox. You can have a try of both of them and balance the search results.
Target your web site content at selected keywords. After finalizing the keywords, you can now build up your web pages with them. But, be careful, don't overuse any keywords on your web pages. Overuse of keywords may make search engine spiders think you are spamming and get your website banned. How can I judge overuse or not?

Make search engine friendly URLs. Although some of the search engines can follow all dynamic URLs, like http://www.scriptmenu.com/detail.php?id=25257, some of them still prefer static URLs ended with html, htm, etc. To make search engine friendly URLs, you can create real static pages, but you don't have to. The web server URL rewrite engine can make this job much easier by reinterpreting the URLs before getting actual pages. If you need more help or tips on how to implement URL rewrite model, follow the link http://www.scriptmenu.com/detail_24379.html and get a tutorial.
Get quality backward links to your page. Although keywords optimization of your web pages can improve significantly your search engine placement, it is still far from sufficient to get your pages top ranked. You have to get some quality backward links to your websites. You need at least 35 quality back links to make google going to your web site and take a look at you. You can get these quality links by submitting your site to high-ranked web site directories or by writing some quality articles and then submitting them to the high-ranked online article archives. Many other ways exist, but remember, only backward links from quality web sites count. Websites poorly indexed or with very low search engine ranking have no value to you.
Keep on improving your website. By keyword optimization, URL optimization and quality backward URLs, your website should have gotten remarkable search engine placement. However, the placement is not static, you competitors are optimizing their websites and trying to kick you out of your current position. To maintain a good search engine ranking, you have to keep on improving your website. Keep on optimizing your website navigation, content and structure. Keep on getting more quality links from top-rated sites.... The battle for top search engine positions will never end. Good luck, :-)
