Constantly create new web pages
A website is never finished. Creating new pages lets the search engines know that your site is active. The more pages you have the more words you have that can rank in the search engines. Don’t just add content for the sake of adding content. Make it useful information that helps your visitors. If you have a database of a lot of content don’t add it all at once if you don’t have to. Slowly add content. Watch your log files and see when your sites gets a full crawl from the search engine bots. Add the content after each crawl. You can also create a blog. If you don’t want to or can’t write your own blog posts talk about current news that is relevant to your industry.
