1. Submit your site to Web Directories. This is a pretty monotonous process that can get you several hundred backlinks if you have the time. An alternative would be to hire a manual directory submitter. Here’s a list of web directories you can use. You can also find some blog directories here.

   2. Submit Press Releases to PR sites. A basic press release about your website’s launch can be released to several PR websites, who will distribute it to various online news outlets. A good way to get a free link. I recommend using PRWeb and PRLeap.

   3. Reciprocal Links with Similar Websites. Its important to pick sites that are of high relevance so you’ll not only get links but traffic. Reciprocal linking can be useful from the beginning but don’t overdo it. You can find link partners by emailing them directly or searching through webmaster forums.

   4. Squidoo Lenses. A Squidoo lens is fairly easy to create. It only takes around 15 minutes to set up one fully and you’ll be able to insert a bunch of anchor text links to your website along with your feed content. Hubpages is another similar site you can use.

   5. Article Submissions. Create a short article on your niche topic and submit it to article directories for a backlink and some traffic. You might get more links if your article is picked up and published on other websites. Here is a list of article directories, sorted by Alexa and PageRank.

   6. Social Media Profiles. There a whole bunch of social websites online which allow you to insert a link to your website on the profile page. Sign up for some of them, preferably using a username and avatar that brands your business or you as a person. This might come in useful when you decide to promote your site via the social website in the future.

   7. Social Bookmarking/Voting Websites. Certain social voting websites like Netscape or Digg are often crawled by search engines and their links do help to get a website indexed. 3spots has the biggest list of social voting and bookmarking websites I’ve seen so far.

   8. Forum Signatures. Sign up for some forums in your niche and start contributing to ongoing discussions. Insert a link to the homepage or some inner pages of your site.

   9. Create a Tool, Theme or Widget. Pay a designer to come up with an add-on application or template that is related to a specific social network, popular website or platform. Include a credit link that points back to your designated website.

  10. Blogs on Other Blog Platforms. Use existing blogs you have on other blog networks. Or set up different versions of your blog on different blog networks like Wordpress.com, Blogger and Xanga. Link to specific webpages on your website.

  11. Comment on Other Blogs. Start commenting on relevant and popular sites in your niche. Don’t just spam for links but focus on building a relationship with other bloggers as well. Write a relevant comment and try to avoid using keyword names or signature links.

  12. Guest posting on other blogs. Like article and press releases, this one involves having readily available content you can send out to certain blogs in your niche. This is great for getting relevant links and traffic.

  13. Hold Contests. Some websites often offer contests in a bid to attract anchor text links from bloggers. An example is this iPhone giveaway on Gary Lee’s site. Contests allow you to determine the specific anchor text but its possible that too many links using the designated keyword may harm your domain instead.

  14. Collaborative Projects. You may need to develop an article specifically for a writing project, blog carnival or meme but it will usually get you a couple of backlinks, depending on the number and generosity of the participants involved.

  15. Offer your Expertise. This will apply if you have a specific skill set such as web design, copywriting, translation or SEO. Write to an established website and offer to revamp/optimize their website in return for a mention or credit link on a webpage. This offers excellent branding, particularly if your offer is picked up by a website with a decent audience.
