Back link Building Tip #1:

Increase Google page ranking by adding your website to the free Qassia directory. You'll get unlimited quality back links (as opposed to "no-follow" back links), and you don't have to add reciprocal back links.

Back link Building Tip #2:

Host your own affiliate program on your own server. Sure it takes more work: you have to set it up, administer it and pay out the affiliate checks. However, if you use an affiliate service, such as Commission Junction, the links point to the affiliate service and get redirected to your site. A more effective strategy is to host your own affiliate program, so all those affiliate links point directly to you. You can find affiliate programs, some of which may be free at The CGI Resource Index (Bill Gentry with Look Sharp Designs)

Back link Building Tip #3:

Increase Google page ranking by finding linking opportunities within discussion lists related to your site’s topic. Warning: do so responsibly and carefully (in other words, don't join a discussion list for the sole purpose of getting back links. Participate and add value to the discussion group). Try Yahoo Groups, which has thousands of topical discussion groups on almost any topic. I often send short posts to appropriate lists with links for my clients’ sites, and if you do so properly, it is very effective. (Eric Ward, President, Net POST and URL wire)

Back link Building Tip #4:

Anywhere you can leave your link, do it: in chat rooms, guest books and social networking sites (the warning from tip #3 applies here as well). You would be surprised at where your link turns up on search engines when you start doing this. And if the search engine has found it, then it adds to your link popularity. (Don Hammond at Dolomite.com)

Back link Building Tip #5:

Now that Google indexes the content of newsgroups, if you post to related newsgroups, be sure to use a signature line with your link and appropriate link text. (Robin Nobles of Search Engine Workshops, Online Search Engine Marketing Courses, and the TNT-Guides for Successful Web Sites.

Back link Building Tip #6:

Ask a question at a site that has a question and answer page and include a link. Post questions on forums that allow links. Post into the newsgroups. Include an e-mail tail tag. Put it on your T-shirt. Include it as a sticker with each shipped order. Tattoo it on your forehead. Tell your mom. Get a vanity license plate. (Michael Campbell with Internet Marketing Secrets)

Back link Building Tip #7:

The number one way I've built link popularity is by offering a good information product or service, establishing a good conversion on the site, and then getting super affiliates. I've found that getting super affiliates multiplies the number of regular affiliates I'm able to get. All of this leads to hundreds of inbound links. It takes a very disciplined approach, but one I've found very effective. (Jon Keel with Improved Results)

Back link Building Tip #8:

I'm surprised at how many people don't have their link in their signature line of their e-mail. (Don Hammond at DonOmite.com)

Back link Building Tip #9:

Don’t get a link from “links” pages on sites as these are about 1% as useful as your signature link on the 7th page of a forum thread, unless of course the Page is a PR 9 with a lot of back-links itself.

Back link Building Tip #10:

If a site wants to link to you from a page with 100 links on it you can basically forget it as the strength of the link is shared by, well, 100 others!

Back link Building Tip #11:

So if you have a site about Dogs you might want to link out to Crufts or the Kennel Club or Wiki a good one.

Back link Building Tip #12:

You need to get into the good neighbourhoods. Try and get links from the neighbourhoods at the top of Google for your key phrases after all Google likes these sites enough to rank them! Find that circle of sites where all the big boys in your industry link to and are linked from and get involved. For instance, try and get a link from a .gov site!

Back link Building Tip #13:

See who links to your competitors and try and get a link as well (or pay money to have their link replaced with yours.

Back link Building Tip #14:

Use Yahoo and type “link:yourcompetitors.com” and see who links to them. Yahoo is kind enough to rank pages virtually by the number of back-links sites have in site explorer - making it one of my most used seo tools.

Back link Building Tip #15:

Don’t waste your time with seo tools! Join Social Network tools like Delicious, Technorati and Stumble. There’s three links right there, although to be fair, they are not actually counted as linksby Google becasue of the Nofollow attribute. Digg links count, though.

Back link Building Tip #16:

If someone, anyone wants to link to you accept, just don’t always reciprocate with a link back to them (negates the value of the link, almost) and could see your site lose trust. Remember Google says it is impossible for a site to hurt your site by simply linking to your site, but you can hurt your site if you link to another site with a ’shady’ backlink profile.

Back link Building Tip #17:

It doesn’t hurt to get a link from a low or high Google Page Rank page. Today’s No-PR page might be a PR 5 page in reality, as Google Toolbar is out of date.

Back link Building Tip #18:

Good Google rankings is not all about who you get a link from it’s who you link to - this is thought to be the measure of the trust of a site and seems fairly reasonable to me. Link to authority sites in your industry as well as other sites that look like quality upcoming sites, and stay clear of suspect sites.
