"We do link building" and "we do digital PR" sound the same to many marketers. Both end with a backlink on another website, so why would the difference matter? It matters because the route there decides the quality of the link, the risk you take and what else you get out of it.

What is link building?

Link building is the active acquisition of links to your website in order to rank higher in search engines. Think guest posts, business directory listings, link swaps and asking sites whether they would link to your page. The starting point is the link itself: which page should be linked, and from which site? What the link adds for the reader of that other site is often an afterthought.

That is exactly its weak spot. Search engines are getting better at recognizing links that exist only to rank. Under Google's spam policies, bought or swapped links can even lead to lower rankings instead of higher ones.

What is digital PR?

Digital PR starts with the story, not the link. You develop an angle with real news value, such as original research, a striking data point or an opinion that moves something. Then you pitch it to journalists and editors who want to show it to their readers. If the story runs, the link follows naturally: as a source, a reference, a piece of evidence. You can read the basics in what is digital PR.

The differences at a glance

  • Starting point: link building starts with the link, digital PR with the story.
  • Type of sites: link building often ends up on blogs and directories with few readers. Digital PR earns placements in news media and trade publications with real authority.
  • Risk: paid or swapped links can trigger a manual action from Google. Earned editorial links are exactly what search engines want to reward.
  • Side effects: a link is all link building delivers. Digital PR also brings brand mentions, awareness and referral traffic.
  • Scalability: link building scales easily but loses value just as fast. Digital PR takes more effort per campaign, but the placements stay findable for years.

Why the mention matters as much as the link

For AI search engines such as ChatGPT and Google AI Overviews, it is not only the link that counts but above all the mention of your brand name in trusted sources. An article in a national publication that names you works even without a hyperlink. Read more in our article on brand mentions and in GEO and digital PR. A guest post on an obscure site adds next to nothing here.

When to choose which

It is rarely either/or. Link building in the broad sense, such as fixing internal links, claiming existing mentions and asking a partner for a link, remains useful as support. But if you want to build authority that lasts, digital PR is the foundation. At Voice Digital we work with data-driven PR, where a campaign lasts a maximum of 8 weeks and links are the result of stories that editors want to run themselves.
