The best way to keep search engines interested in your website is to keep adding new content, this can be hard to do for certain types of companies, for example if your products or services never change then there’s not much you can keep adding to your website, this is where a blog comes into use. If you use a blog like an online diary of anything interesting that happens to be related to your company, then you can add an article to your website, this way your company website begins to fill up with work related content, more people will find your site through search engines and search engines will be more interested.
