It is said that the only constant in life is CHANGE - the same can be said for those looking to the internet for what they seek. Be prepared to continually improve your website content, and also to improve the meta-tags to match 'in-demand' search words used by people that you intend to serve with your website. Routine maintenance could include:

• Check out your website often from a 'new-visitor' point-of-view, and be prepared to improve their experience on your website
• Make sure all the links on your pages go where they're supposed to
• Do a search (at a popular search engine) for routine products or services provided by your industry. See who's well positioned in the search results, and see what they are using in their page titles, descriptions and key phrases, then incorporate the results into your own site
• Consider writing new articles DAILY or WEEKLY for your website to educate your site visitors
