Whether you’re new to link building or have been doing it for a while, we’re sure you’ll find something useful in this guide. The landscape of SEO and link building is always changing, and today, the importance of building high-quality links has never been higher. The need to understand and implement high-quality campaigns is essential if you’re going to compete and thrive online, and that isn’t going to change any time soon.
Link building is the process of acquiring hyperlinks from other websites to your own. A hyperlink (usually just called a link) is a way for users to navigate between pages on the internet. Search engines use links to crawl the web; they will crawl the links between the individual pages on your website, and they will crawl the links between entire websites. There are many techniques for building links, and while they vary in difficulty, SEOs tend to agree that link building is one of the hardest parts of their jobs. Many SEOs spend the majority of their time trying to do it well. For that reason, if you can master the art of building high-quality links, it can truly put you ahead of both other SEOs and your competition.
In order to understand the importance of link building, it’s important to first understand the basics of how a link is created, how the search engines see links, and what they can interpret from them.
Start of link tag : Called an anchor tag (hence the “a”), this opens the link tag and tells search engines that a link to something else is about to follow.
Link referral location : The “href” stands for “hyperlink referral,” and the text inside the quotation marks indicates the URL to which the link is pointing. This doesn’t always have to be a web page; it could be the address of an image or a file to download. Occasionally, you’ll see something other than a URL, beginning with a # sign. These are local links, which take you to a different section of the page you’re already on.
Visible/anchor text of link : This is the little bit of text that users see on the page, and on which they need to click if they want to open the link. The text is usually formatted in some way to make it stand out from the text that surrounds it, often with blue color and/or underlining, signaling to users that it is a clickable link.
There are two fundamental ways that the search engines use links:.
1. To discover new web pages.
2. To help determine how well a page should rank in their results.
Once search engines have crawled pages on the web, they can extract the content of those pages and add it to their indexes. In this way, they can decide if they feel a page is of sufficient quality to be ranked well for relevant keywords (Google created a short video to explain that process). When they are deciding this, the search engines do not just look at the content of the page; they also look at the number of links pointing to that page from external websites and the quality of those external websites. Generally speaking, the more high-quality websites that link to you, the more likely you are to rank well in search results.
Links as a ranking factor are what allowed Google to start to dominate the search engine market back in the late 1990s. One of Google’s founders, Larry Page, invented PageRank, which Google used to measure the quality of a page based in part on the number of links pointing to it. This metric was then used as part of the overall ranking algorithm and became a strong signal because it was a very good way of determining the quality of a page.
It was so effective because it was based upon the idea that a link could be seen as a vote of confidence about a page, i.e., it wouldn’t get links if it didn’t deserve to. The theory is that when someone links to another website, they are effectively saying it is a good resource. Otherwise, they wouldn’t link to it, much in the same way that you wouldn’t send a friend to a bad restaurant.
However, SEOs soon discovered how to manipulate PageRank and search results for chosen keywords. Google started actively trying to find ways to discover websites which were manipulating search results, and began rolling out regular updates which were specifically aimed at filtering out websites that didn’t deserve to rank.
This has also led to Google starting to discount a number of link building techniques that were previously deemed fine, for example, submitting your website to web directories and getting a link in return. This was a technique that Google actually recommended at one point, but it became abused and overused by SEOs, so Google stopped passing as much value from that sort of links.
More recently, Google has actively penalized the rankings of websites who have attempted such overuse of these techniques—often referred to as over-optimisation—in their link building. Google’s regular Penguin updates are one such example. Knowing which link building techniques to avoid and stay within Google’s guidelines is an important subject.
