Chapter 1: Link Building Basics
For a long time now search engines have been using links as votes, which represent the web’s opinion on what pages users find relevant and useful based on popularity. After years of programming development, the search engines have mastered and refined the use of link data, where complex algorithms are put in place to create nuance evaluation of websites based on this information.
Links are not the entirety of SEO, but most search experts agree that huge portions of search engine algorithms are designed around link-based factors. By using links, the engines can determine a site’s popularity in a specific niche based on the number of pages linked to it and when this information is combined with other metrics like trust and authority, the search engines assign a rank for the website.
Trustworthy sites usually link to other trusted sites while spammy sites get the fewest links from trusted sites and links are a great way to establish the validity of documents on any given subject.
What is Link building?
Link building refers to the process of getting external pages on the internet to link to your own website. The more important and popular a website is, the more the links from that website matter. A popular site such as Wikipedia has thousands of different websites linking to it which means it’s probably an important and popular site. In order for you to earn popularity and trust with the search engines, you need assistance from other link partners. The more important the site, the better.
The Basics
Link building is one of the most challenging parts of SEO but also the most important to success. In order to succeed in link building you will need a decent budget, hustle, and more importantly, creativity. Each link building campaign is unique and the way you choose to build your own links will depend largely on your website as well as your personality. Your strategy should fall under one/or more of these types of link acquisition:
As with any successful marketing effort, you need a strategy and realistic goals. But before you embark on a link building effort you should probably take time to read and understand the many elements of a link as used by search engines and how those same elements factor into the valuing and weighing of your links.
Many search engines exist today and those search engines use links in a variety of ways. We might not know all the attributes considered by the engines but through proper analysis and hands-on testing we can draw some informed assumptions that hold up in the real world.
Here is a list of the most notable factors worthy of your consideration. Professional marketers consider these factors when measuring the value of a link and a site’s link profile.
Topic-Specific/Local Popularity
This concept of “local” popularity was first used by the Teoma search engine and it suggests that links originating from websites within a topic-specific community carry more weight than links from other general off-topic sites. Let’s say for instance your website sell car parts, and you earn links from the Society of Automakers; the links would matter more than earning links from an off-topic, dog breeding site.
It’s one of the strongest signals used by search engines when ranking sites. If a high number of links point to a specific page with the right keywords, then that page will have a higher probability of ranking well for the keyword used in the anchor text. This can be observed with searches like “Click here”, where a significant number of results rank mainly due to the anchor text of inbound links.
Trust Rank
The website is filled with spam. As much as 60% of web pages are in fact spam, so search engines have to find a way to weed some of this content out. They do this by measuring a site’s trust with the link graph. When a site earns links from high-trust domains such as government websites and non-profit organizations it boosts their score in this particular metric.
The Link Neighborhood
Spam links mostly link to other spam sites. Spam goes both ways and search engines look at the totality of these links in aggregate so they can understand which “neighborhood” the website falls under. Therefore, it’s a good idea to be selective when you choose sites to link to and also when you attempt to earn links from a site.
Social Sharing
Social media has seen an explosion in the amount of content moving through different platforms such as Facebook, Twitter and LinkedIn. The rise in social sharing has led Google to incorporate social signals in search results in an effort to serve personalized results. Some of these personalized results are not included in the first page but they still get promoted because of the surging social influence.
Individuals who share a lot of material across different social plat
Search engines don’t treat socially shared links the same way they do other links but that doesn’t mean they don’t notice them. There’s been heavy debating over how exactly search engines factor in social links into their algorithms but its obvious social channels are of great importance.
Freshness
You may not have known this but link signals decay over time and websites that were once hugely popular go stale, eventually failing to earn new links. Because of this, it is crucial to keep earning new links over time. Search engines use the “FreshRank” feature to determine a site’s freshness and judge current relevance.
An aside on backlinks
Bing and Google have been trying to discount the use and influence of paid links on their search results. Obviously it’s not possible for them to detect all paid links, they have been putting in a lot of time and resources into formulating ways to detect and discredit the practice. If you get caught buying links you risk severe penalties that will probably kill your rankings and send your site to oblivion.
Importance of Backlinks
When you look at it in terms of building your site or blog, you will find several important factors which play a part in your overall SEO plan:
One of the many ways to find out how well your site ranks on a search engine is to search for one of the key phrases targeted by the page. For instance if you want to rank well for a phrase such as “diet pill” then it would help if you earned links from pages that already rank well for that particular phrase.
It takes a lot of practice, effort and experience to establish these variables as they affect your ranking but you can always use one of the many web analytics to find out whether your campaign is gaining traction. You know the strategy is working when you see an increase in search traffic, frequent search engine crawling and better rankings, among other things. If you don’t see a rise in these metrics then its possible you need to work on your on-page optimization or pursue better quality link targets.
