Great sources for incoming links? You don’t need a lot of links. Just a few from the right places such as:
Directories. Register with DMOZ, Yahoo, Google, your industry associations or authorities.
Vendors, business partners, even customers in your industry. When selecting from this list, check out which ones are already listed in DMOZ and other directories — links from their sites will be more valuable to you in building your credibility with search engines.
Industry newsletters. Volunteer content and ask that they link to your site.
Relevant .edu and .gov Web site links score well with search engines.
Press releases. Hyperlink your company name and include your URL in contact info.
Blogs. Post news, tips, updates that others will value and link to you as a resource.
