3. 46.5% of SEO professionals allocate between $5,000 and $10,000 to their link building budgets every month

When uSERP surveyed 800 SEO professionals, they discovered that 46.5%, which was the majority, spend between $5,000 and $10,000 on link building each month.

03 Link Building Monthly spend03 Link Building Monthly spendPin

35.5% spend between $1,000 and $5,000 per month while the remaining 18% spend over $10,000.

Link building costs are hard to determine as oftentimes, it’s not as simple as paying a website “X” amount of money to insert a link on their site.

This isn’t how high-quality backlinks work, at least.

If the website you’re requesting a backlink from has a high domain authority, a lot of traffic and a huge social media following, expect to pay more.

Link building costs are also determined by the methods you use to obtain them.

While some blogs offer backlinks for free or accept them in exchange for guest articles, link building methods like digital press releases that involve high-traffic websites will often cost more.

For context, these are the types of companies these professionals do SEO work for:

  • Personal Website: 25% of respondents do SEO work for their own websites.
  • Freelancer/Contractor: 20% of respondents do SEO work on a freelance basis.
  • Agency: 16% of respondents do SEO work as part of web design agencies who work with a variety of different clients.
  • In-House SEO: 15% of respondents do SEO work as salary employees for individual companies.
  • Consulting/Strategy: 12% of respondents provide SEO consultations and SEO strategy services.
  • Other: 12% of respondents do other SEO work.

6. 56.3% of SEO experts think link quality and quantity are important for link building

uSERP’s survey of 800 SEO professionals revealed a few interesting link building statistics.

It revealed that although only 7.8% of professionals think quantity is more important for link building and 35.9% think quality is important, 56.3% of respondents think both quality and quantity are important for link building.

This means that while SEO professionals think quality is more than 4x as important than quantity, more than 50% think both are important.

When asked to provide more context for their response, here’s what one respondent had to say.

They explain how digital PR link building helps their company focus on earning quality backlinks rather than many backlinks:

“Building links with digital PR tactics pretty much implies that we value quality over quantity.

By creating content that’s attractive for the media (think original research, expert commentaries, visually-appealing infographics, and newsworthy stories that are timely, impactful, relevant, human-interest, or feature an influencer), sharing it with the public, and actively reaching out to relevant media contacts, we can not only build links but also strengthen the backlink profile, gain more credibility, and, ultimately, rank higher in search engines.”

13. 88% of SEO professionals believe nofollow links provide just as much authority as dofollow links do

Nofollow links have been the subject of many a debate over the years.

URLs have special tags that tell search engine crawlers, such as Googlebot, what they’re supposed to do with them.

Two such tags are the “dofollow” and “nofollow” tags.

When you insert an external link on a page on your site, you have the ability to make it dofollow or nofollow.

A dofollow tag tells the search engine crawler to follow the link and transfer link equity, also known as link juice, between your web page and the page you’re linking to.

A nofollow tag tells the search not to follow the link or transfer link juice between the two pages.

Nofollow links are thought of as being completely cut off from the ability to impact search rankings, which is why this statistic is so surprising.

When asked whether or not they think nofollow links improve authority and search engine rankings, 54% of SEO professionals said yes.

13 No follow links13 No follow linksPin

34% said maybe while the remaining 12% said no.

This means 88% believe nofollow links are still able to improve rankings despite not being able to transfer link equity.

Here’s what Dima Suponau, co-founder of Number for Live Person, has to say about nofollow links being important for authority even if they don’t transfer link equity:

“I totally agree with the point that nofollow links are valuable, bring authority and recognition. The biggest outlets out there stick with Google’s agenda on links and almost all of their links are nofollow, no matter how they got them.

But, having a backlink on their websites is still worth an effort since even though the link is nofollow, it generates traffic to your website. Personally I have backlinks on Forbes and they are nofollow, but I believe they are far more valuable than dofollow links from websites with no significant traffic and authority.”

14. 58% of SEOs think that backlinks leading to the page you’re trying to rank is most important when using link building strategies to rank a specific page

Aira’s survey revealed that 58% of SEO professionals think backlinks that lead to your target page are more important when using link building strategies to get that target page to rank.

The site also included “links to the domain as a whole” as an option.

14 Market Size14 Market SizePin
