SEO 101 - Part 15: Everything You Need to Know About Linking

The following series is pulled from a presentation I gave to a group of beauty bloggers hosted by L'Oreal in New York. Most of the presentation is geared toward how to make a blog more search engine and user-friendly, however I will expand many of the concepts here to include tips and strategies for sites selling products or services across all industries.
Links come in all different shapes and sizes. Some good, some bad, some are just there. In part 14 of this series we looked at the anatomy of a link, analyzing the different elements that make a link what it is. There are a lot of things to consider when looking at the value of the link, many of which lie in the the value of the page or website doing the liking. But here we'll look at a slightly different value of link, in how it's linked between the two sites.
There are three basic ways of linking between sites, One-way, reciprocal and multi-way. We'll take a look at these, their values and whether its a type of linking you should be engaged in.
Reciprocal Links
Reciprocal Links
A reciprocal link, in simplest terms, is a link from Site A to site B and a link back from Site B to Site A. Many have written reciprocal links off as being completely irrelevant but that's far too simplistic. There is nothing wrong with reciprocal links in an of themselves. Its all in the execution.
Low-Quality Reciprocal Links
Low Quality Reciprocal Links
The lowest quality reciprocal links are those found on pages specifically designed to house reciprocal links. What you get from these "resource" pages is a bunch of barely related links from Site A to one or more dozens of other websites. All of these build their own "resource" pages that do you the favor of linking back to you and one or more dozens of other sites.
These pages are usually easy to spot because they generally provide little value to the visitors of the site, other than for a good laugh. If you find yourself linking to a site that links back this way it would probably be of benefit to you to stop linking to them. The link pointed to you likely has no value, however by associating yourself with them (via your link) you can be sending the search engines a signal that you don't care much about the quality of sites you link out to.
High-Quality Reciprocal Links
High Quality Reciprocal Links
Despite the belief of some, there are reciprocal links that can pass a lot of value to you. Low-quality reciprocal links are there simply for the quid pro quo of the link. High quality reciprocal linking has nothing to do with doing someone a favor in order to get something in return. These are two links that are made independently of each other simply because you, and the "reciprocating" site find each other's content valuable.
It's entirely possible that one of the linking parties has no idea the other site is linking to them because each link was given entirely on the basis of the value of the content being linked to. It wasn't pre-arranged or purposeful in any way.
That doesn't mean you can't pre-arrange a reciprocal link and still make it valuable. You can, you just need to make sure it looks as natural and non-pre-arranged as possible. Linking and receiving a link in the midst of quality content in primary site pages can do the trick. Just be careful about how many of these reciprocal links show up at the same time.
Multi-Way Links
Multi-Way Links
This is where some of the link schemes get clever. Reciprocal links, we are told have no value so you have to have three or more site's linking together so there is no direct reciprocating link at all.
Three-way link schemes aren't all that difficult for search engines to sniff out so these multi-link programs have gotten more complex. The latest version is link wheels. This is where networks of sites link to a second level of sites which then link to you. You get dozens or hundreds of "one-way" links to your site through these link wheel networks.
Like most linking schemes these link wheels will probably have limited value over the short-term without any real long-term benefits.
One-Way Links
One-Way Links
On a pure value standpoint, one way links (sans any linking schemes) are the most valuable links you can get. This is, in most circumstances, a link to your site from someone that finds your content valuable, doesn't ask for a link back, you don't link back to them on your own.
If you have good content, this type of link isn't all that rare. The best link marketing is creating a valuable website that is informative, helpful and educational. Of course this isn't proactive marketing, which is why you see a lot of options to purchase one-way links.
Without a doubt, search engines frown on purchased links that are not clearly defined as such both visually and/or using the nofollow attribute. Purchase links at your own risk. If you are using a broker that claims to keep their purchased links hidden from the search engines, keep in mind that the search engines can easily spend money building sites and purchasing links from these same networks. The hidden network is no longer hidden from the search engines and they might not even be aware of it.
Not all purchases links have no value, but only so long as the link flies under the search engine radar. This can rarely be done by purchasing links from a broker, but can be done on a one-on-one situation.
Links are an important part of your optimization campaign, but not every link will provide you the same value. Aside from worrying about reciprocal links, link wheels or even purchasing one-way links, go outside of the box of "get me a link" and think about providing value to your visitors that is worth linking to. Once you have that, then consider ways to get the word of your content out to those that are most likely to link, become customers, and spread the word.
