Avoid questionable link building strategies
Be careful!  If you see a link building opportunity that appears suspicious, ignore it. You could be wasting your time or even risk having your site penalized for significant periods of time by search engines. It’s up to you to verify legitimacy and value of any agreements. 

“White Hat” SEO practices refer to safe, honest and trustworthy methods of obtaining links.  “Black Hat” practices are unscrupulous site design or link-building methods with the purpose of cheating or tricking search engines.  Examples of these “bad guys” are excessive use of keywords on a page or sites designed purely to list links.

Post links everywhere you can think of
Include your web address in any online information about yourself.  Your fraternal organization, church, college alumni association, civic association, sports or activity club, networking group, support circle, may allow you to post a personal profile where you can add a link or even brief advertisement.  Ask friends to link from their MySpace page!

Submit yourself to awards sites
Find sites that offer to post your link as a “site of the day” or any other reason.  One place to start is http://CoolSiteoftheDay.com, which ranks highly in search engines.

Use affiliate programs to get linked
If you have a product, start your own affiliate program and email related sites who’d like to add another stream of income.  Not only might you earn cash yourself, but each affiliate gladly provides another inbound link to help you climb higher in Google and Yahoo!  http://Clickbank.com is an easy way to use a system already in place (for digitally delivered products only).  Join for $50 and affiliates post a banner or text link to automatically receive credit for customers who purchase through their links.

Publish in other people’s newsletters
Offer to write articles for eZines or email newsletters of associates (and even competitors) in your industry.  Anyone publishing regular materials needs content, so your “payment” may be a link to your site, along with a one-sentence description.

Internal page links
Even internal links (within your site) can help.  This includes anchor links within a page to jump from one area to another.

From SEO-guy.com:  “Anchors are used to reference specific locations on a page from other locations on that same page. These “on page links” are yet another place to get your main keywords in and boost that “on page” density.

An example is “back to the top” at the end of a page. Except as smart optimizers, we use our keywords instead of phrases like “back to top”. Here is an example:
At top of page I place my anchor: a name=”seo”
Farther down,  I put SEO (instead of “TOP”)
I’ve now created a same page link containing my keyword and thus increased my density as well as received added weight by virtue of it being an anchor.”

Relative value of links
As with the entire “Google formula” for calculating rankings, the value of links has it’s own complicated formula.  Anchor text, relevancy of the other site, page rank of the other site, number of links per page and the other factors play a role.  Even the words [or search terms] in text surrounding a link affects it’s quality in the eyes of Google. 
Just remember that all links are not created equal!

Reciprocal Links: friends and associates
Trade links with business associates and anyone else you know with a website. Contact fellow members of associations, your chamber of commerce, social organizations, or any group you’re part of. Place links to each others’ sites since you already know and trust them. Maybe you’ll be allowed a longer description or preferred page placement because of your relationship.

It’s more helpful if the site content is related, but even being located in the same geographical area lends a degree of “relevance”. If people aren’t capable of adding links, they should contact Attraction Web Design for help [nice shameless plug].

Reciprocal Links: the open market
Trading links has always been a popular way to increase the number of inbound links. Exchanging links allows both sites to benefit, so everyone is happy (including the hungry S.E. tiger!!). This can be a time-consuming measure, so there is software that can be bought and there are online services to automate the process. One worthwhile service with both free and fee options is http://www.LinkPartners.com.

• Links are more valuable from highly ranked sites with good traffic, so a link from Microsoft gives you more credit than one from Joe’s Computers.
• Avoid FFA Link Farms – A FFA (Free For All) website enables any website owner to place their link on a web page. These are worthless, since search engines despise this practice and won’t give you credit.
• Ensure that your link is actually posted on the other site and that it is not just a bogus “Link Farm” itself, meaning there is no site content.
• Fewer links on a page means more “link juice” to be divided among them, so if your link is on a page with over 100 others, it may be virtually worthless.
