What These Link Building Statistics Mean?

Here are my top four takeaways from analyzing hundreds of link building statistics and numbers.

Take 1: Links Are Still Valuable

Google’s updated Link Spam Guidelines warn SEOs off using a wide array of link building tactics. Many long-considered white hat link building tactics, such as guest porting and digital PR, could easily fit under these arbitrary definitions. 

Yet the latest stats indicate that SEOs continue to see a difference between what Google says and what they do. 28% of SEO budgets go towards link building, meaning that a lot of money back up the belief that links are still incredibly effective.

SEOs still firmly believe in the power of links, because over 78% of them see a positive impact and ROI from their link building activities.

My interpretation of this is that Google’s algorithm still heavily relies on links to determine who ranks at the top. Their real goal is to show the best results at the top. If they rely too much on links, which can be manipulated, it messes with their ability to show users the best results. 

This, I believe, is why they go to such efforts to dissuade sites from building lots of links.

Take 2: The Best Tactics

Almost two thirds of link builders today use Guest Posting. That is a full 8 years after Google’s Matt Cutts declared that Guest Posting was dead in 2014.

Our experience has been that there are a lot of so-called Guest Post Farms these days. We don’t believe that most of these links have any positive effect on SEO. Some SEOs still value links from these sites because they have high DR or DA.

Google used to hand out unnatural link penalty notices for getting too many bad links. These seem to happen a lot less these days. Instead, Google is simply ignoring many of these links.

As SEOs increasingly move beyond basic guest posts, more difficult tactics like Digital PR promise higher value links. Yet SEOs tend to shy away from Digital PR, despite experienced SEOs rating it as highly effective.

Platforms like HARO and Qwoted has also seen explosive growth in recent years. This isn’t necessarily a good thing the SEO ‘race to the bottom’ effect means that spammy answers seeking links clog us these platforms. While they are still effective, it’s now best to use them as part of a diversified array of link building tactics.

Some SEOs don’t even bother with active link building in less competitive niches. Instead, they produce a lot of content and rely on the natural / passive links that this content acquires over time. The problem is that this tactic will not work in more competitive spaces where everyone invests a lot in link building.

Still, with almost 90% of marketers creating content with the intention of acquiring links, this is a core tactic when supplemented with active link building. A Backlinko study found that long form content gets 77.2% more links than shorter content. This may be why we’ve seen a definite trend in recent years towards longer and longer content in competitive spaces.

Take 3: Experience counts

Our recent link building survey found that the most experienced link builders built 25 links per month, on average. The lease experienced link building, however, only built 7 per month.

While this wasn’t surprising, what was surprising was that the cost per link worked out significantly cheaper, when these stats were cross-referenced with link builder salaries.

average cost per link based on experience

For most businesses, it works out cheaper to hire experienced link builders. It also makes practical sense, since 41% of SEOs see link building as the most difficult part of SEO.

Another interesting trend is how success gets measured. Experienced link builders look beyond the DR or DA of a link and instead measure success by looking at traffic or rankings. 

With the easy link building tactics becoming saturated, experience will count even more in the future. Skilled, experienced link builders will be required to get the best links.

Take 4: The Future of Link Building

In our 2023 SEO Predictions Podcast, we talked about Google devaluing and ignoring lower quality guest post links. Our view is that SEOs don’t yet realize that some of the links they are building are doing nothing.

Google’s John Mueller recently said

Over time, the weight on the links at some point will drop off a little bit as we can figure out a little bit better how the content fits in within the context of the whole web.

There are two ways to look at this. 

The first way is that Google is saying links will become less valuable over time. The statistics among link builders do not align with this, as almost two thirds believe links will have the same or higher value in 5 years time.

will links impact rankings in next 5 years

The other way to look at this though is that Google is freely admitting that links currently do have a high weighting in the algorithm.

Final Thoughts

Looking at reliable link building statistics to gauge the sentiment of the industry is really important. The Google algorithm is weighted differently from how Google would like you to think it is.

Links matter a lot. And they will continue to matter, at least for a while.
