[0:00] Hey, it's Sam Oh and welcome to the third lesson in the link building module. [0:03] Today, we're going to talk about the attributes that make a backlink good or "high quality." [0:09] As I said in the last lesson, not all backlinks are created equal. [0:13] For example, if you spammed forums with links to your site, those wouldn't and shouldn't hold [0:18] more weight than let's say a link from The New York Times. [0:22] Otherwise, backlinks would just be a game of quantity and Google's search results would [0:26] reward the biggest spammers. [0:28] Fortunately, ranking on Google doesn't work that way and quality backlinks are still [0:33] a prominent ranking signal. [0:35] So with that said, let's talk about the 5 attributes that make a backlink "good." [0:39] The first attribute is relevance. [0:41] Imagine this for a second. [0:43] You're going to visit Greece for the first time next month and you need recommendations [0:47] for places worth going to. [0:49] Now, you have a friend that has lived in Greece for their entire life and obviously [0:53] knows every nook and cranny. [0:55] You also have a friend in the US who hates traveling and has never been [0:59] outside of the states. [1:01] Who's opinion would you hold higher? [1:03] Obviously your Greek friend. [1:05] In the same way, links from a website about travel or Greece would hold more weight than links from [1:10] sites about technology or marketing because they're more topically relevant and authoritative. [1:16] For example, you'll see that this page is ranking #1 for the query "how to devein shrimp." [1:22] If we look at their backlinks and also filter by one link per domain, we can see their backlinks [1:27] from different websites. [1:29] Now, if you don't have an Ahrefs account, then you can still see backlinks pointing [1:32] at pages using our free backlink checker tool, which I'll leave a link to in the description. [1:38] Going back to the backlinks report, you'll see this page from Wikihow which is called [1:42] "3 ways to peel and devein shrimp." [1:45] So the link is on a very relevant page. [1:48] Scrolling down a bit, you'll see this link from a page called "shrimp with garlic sauce" [1:52] which again is relevant at the page level. [1:55] But you can also see that it's relevant at the domain level too just by looking at their [1:59] domain name: slimpalate.com. [2:03] Both of these links are great from a relevance standpoint, whereas a link like this one isn't [2:07] very relevant at all. [2:09] The page is about Firefox 3.5, which is a web browser. [2:13] It comes from a site about video games and computer hardware. [2:16] So an ideal link would be contextually placed within the body of the content where someone [2:21] is quite literally recommending or referencing you. [2:25] Alright, the next attribute of good quality links is authoritativeness. [2:29] If you're unfamiliar with "authority" in the context of backlinks, it basically represents [2:33] the so-called "link power" a web page has. [2:37] And this relates to how Google's PageRank works. [2:39] As we discussed before, both the quantity and the quality of links matter. [2:44] So the more quality links a page gets, the more PageRank it earns. [2:49] And the more PageRank it has, the more authority it can pass to other pages through hyperlinks. [2:54] For example, let's say that page C has two links: one from page A and one from page B. [3:01] Page A is stronger than page B, and also has fewer outgoing links. [3:06] Feed this information into the PageRank algorithm, and you get the PageRank of page C. [3:11] Now, this is obviously a simplified version of how PageRank works, but the key point [3:16] here is that getting links from high-authority pages will likely have the greatest impact on [3:20] your rankings. [3:22] Now, while Google doesn't provide PageRank or website authority scores, we have two metrics [3:27] at Ahrefs that try to quantify it. [3:29] Domain Rating is our website authority metric and it represents the overall strength of [3:33] a website's backlink profile. [3:35] And URL rating is our page-level authority metric, which represents the overall strength [3:40] of a page's backlink profile. [3:42] And you'll find both of these metrics throughout most of our tools, giving [3:45] you insights on referring pages. [3:48] Now, we've covered two very important parts of good quality backlinks, but what we haven't [3:53] talked about yet is the actual link itself. [3:56] So let's break down the anatomy of a hyperlink and talk about how the different parts relate [4:01] to SEO. [4:02] Here's what a link looks like to your website visitors. [4:05] And if we look at the HTML code, then it would look like this. [4:09] Now, there are 3 basic parts to a link that matter in SEO. [4:13] The destination URL, anchor text, and the "rel" attribute or lack of one. [4:18] The destination URL is simply the URL the person will visit when the link is clicked. [4:23] The second part of a link is the anchor text. [4:26] The anchor text is the clickable word, phrase, or image attached to the link. [4:30] So in our example, Site Explorer is the anchor text, which is the name of our competitor [4:35] analysis tool. [4:37] Google uses anchor texts to better understand what a page is about and what terms it should [4:41] rank for. [4:42] But building lots of links with keyword-rich anchors is an example of a link scheme, [4:47] and may result in a Google penalty as it looks unnatural. [4:51] For example, if you had a post on the best golf balls and had a hundred links pointing [4:55] to it where the anchor texts were all "best golf balls," then it would look [5:00] and be quite unnatural. [5:03] People often use anchors such as the company's brand name, the title of the page, the URL, [5:08] or phrases like "click here." [5:10] And here's some proof. [5:11] If we look at the anchors of backlinks pointing to our data study on featured snippets, you'll [5:15] see varying anchor texts like "ahrefs," "old studies," "ahrefs study," "research," and even [5:22] specific stats like "12.3% of search queries" and "99.58%," and so on. [5:29] In fact, there are only 16 websites that have linked to us using the anchor text "featured snippet." [5:36] With most earned links, you have very little or no control over the anchor text, so [5:40] over-optimization isn't something you really need to worry about. [5:44] And the last part of the link we'll talk about is the "rel" attribute. [5:48] Some links contain a "rel" attribute, which is intended to tell crawlers about the relationship [5:53] between the linking page and the linked page. [5:56] And the three "rel" values that you should know about when it comes to link building [5:59] are nofollow, UGC, and sponsored. [6:03] Historically, nofollow links told Google that the linking page would rather not associate [6:08] themselves with the linked page. [6:10] And for that reason, Google didn't transfer "authority" through those links. [6:14] But then Google added a couple other "rel" values: UGC, which stands for user-generated content, [6:20] and sponsored, which signifies an ethical paid link. [6:24] They also announced that going forward, they would look at these link attributes as "hints," [6:29] meaning, they may pass value through them at their discretion. [6:33] Now, if a link doesn't have any of these "rel" values, then it would be called [6:36] a "followed" link. [6:38] Meaning, the link can pass PageRank and help boost your rankings. [6:42] Seeing as this is still relatively new, I'd recommend focusing on building "followed" [6:46] links, although that's only partially within your control. [6:50] Now, it's important to note that nofollow and UGC links aren't bad. [6:54] It's just that followed links are proven to pass authority. [6:58] One final thing I want to touch on is link placement. [7:01] Prominent links are more likely to be clicked, and it's believed that Google takes this into [7:05] account when determining how much authority a link transfers. [7:09] For instance, an editorial link is more likely to be clicked than a link in the footer. [7:14] So, all else being equal, the former would be better than the latter. [7:18] So to summarize: [7:20] An ideal link would come from a relevant and authoritative page where the link is "followed." [7:25] It would have a descriptive anchor, and be placed contextually within editorial content. [7:31] But the truth is, a lot of this is out of your control. [7:34] What is in your control is how you spend your time building links. [7:39] By using these 5 attributes to help qualify prospects, or people that are worth contacting, [7:44] you'll spend your time building links that will actually move the needle. [7:49] Now, the easiest way for a beginner to start building links is to use tried and tested tactics. [7:54] And we'll be covering a few of them in the next lesson which will be published tomorrow. [7:58] So make sure to subscribe so you don't miss out on that lesson and if you're watching [8:01] this video at a later time, then check the description because all of the links [8:05] to the course will be updated there. [8:07] I'll see you in the link building tactics lesson.
