Search Engines love content, actually they crave fresh content, after-all thats their raison d’etre (theire reason for existing) to spider and index fresh original content.
If your site’s homepage is updated on a daily basis with fresh unique content, this will ensure that Google et al will visit (with time) on a daily basis to spider the new content you have to offer.
If you don’t have the time or the budget to add fresh new content on a daily basis, then here’s a little tip…
Add a few RSS feeds on your site’s home page but make sure they’re related to your industry. Also make sure that these feeds are search engine friendly, some are not. The feeds that are not search friendly use javascript to output the feed. Javascript cannot be read by search engines. Make sure to output you feed with languages such as php or asp.
RSS Content Builder is a good tool that I’ve used to output rss feeds on one of my sites, its really easy to use and gives you the option to output your feed using Javascript or PHP, guess which one I use ;-)
