Outsource: When should you hire someone to assist with optimizing your site. If you don’t have time to spend 3-4 hours per month minimum or if you feel your skills are better used in another area of your business or if you need help with ideas on how to improve optimization.
Press Release: Sending out releases over the wire services and posting releases for the media help add links to your site because other sites pick them up. Additionally they provide content to keep your site fresh.
Q&A: Add a Frequently Asked Questions page, even if you don’t like them; Search engines do.
Ranking: Avoid linking from a site below yours. To check a page rank for a site on Google you can use a free online resource: http://www.prchecker.info/check_page_rank.php Sites which have high rankings include: Forbes.com 7 (out of a possible 10), Prnewswire.com 8/10, biz.yahoo.com 6/10 and CNBC.com 7/10.
Site map: This is an old technique but having a site map still helps search engines index your whole site.
