Digital PR link building is the practice of earning coverage that happens to carry links, by giving journalists something worth writing about: original data, a genuine expert, a story with a local angle. Done properly it is public relations with a search benefit. Done badly it is link buying with a nicer name, and the difference is not stylistic, it is the difference between a campaign that compounds and one that puts the site at risk. Google documents the boundary in unusual detail, which makes this one of the few marketing purchases a buyer can audit against the supplier's own regulator. This page sets out where the line sits, what a real campaign produces, and how to check what an agency actually built.
Where Google draws the line
Google's spam policies define link spam as links intended to manipulate rankings, and name the specific behaviours: buying or selling links for ranking purposes, including exchanging money, goods or services for links, excessive link exchanges, and low-quality directory or bookmark site links. The policies also cover requiring a link as part of a terms of service or contract, and articles or guest posts distributed at scale with links back. Google's guidance on qualifying outbound links completes the picture: where a link is a paid placement or an advertisement it should carry rel sponsored, and rel nofollow signals that a site does not want to pass ranking credit. The consequence of ignoring this is stated plainly in the policies, since sites that violate them may rank lower in results or not appear at all. A digital PR campaign that pays for placement and does not mark it is not a grey area.
What a real campaign actually produces
Legitimate digital PR starts with an asset a journalist wants: survey data nobody else has, an analysis of a public dataset, a genuinely useful tool, or an expert with something specific to say about something happening now. The output is coverage, and coverage brings a mix of linked and unlinked mentions, follow and nofollow attributes, and a long tail of syndication you did not plan. That messiness is the signature of the real thing. A report showing thirty follow links from thirty domains you have never heard of, all in the same month, all with keyword-rich anchor text, is a signature too, of the other thing. Judge a campaign on whether the coverage would have been worth having if links had never existed, because that is the test Google's policies are effectively applying.
Disclosure rules that apply beyond search
Where a campaign involves paying or gifting a creator, publisher or reviewer, advertising law applies alongside search policy. The Federal Trade Commission's endorsement guides require a material connection between an endorser and a brand to be disclosed clearly and conspicuously, and the FTC's guidance for influencers says a disclosure has to be placed with the endorsement itself and is likely to be missed if it appears only on a profile page, at the end of a post, or behind a click on MORE. It also says a disclosure in a video belongs in the video rather than only in the description, and that disclosures should not be mixed into a block of hashtags. If an agency's outreach includes gifting or payment, ask how disclosure is handled and who checks it, because responsibility does not end with the agency.
How to audit what your agency built
Ask for a full list of every link acquired on your behalf, with the URL, the date, the anchor text and the method used to acquire it. An agency that cannot produce this is either not tracking its own work or is not willing to show it. Spot-check ten of them: read the article, decide whether a person would have published it without payment, and check whether comparable outbound links on the same site carry rel sponsored. Ask what the agency would do if Google issued a manual action, and whether removal and disavowal are included in the fee. Require that placements are never bought without disclosure, in writing. When you compare the best link building agencies, the useful evidence is what each publishes about price, minimum engagement and named clients, not the domain rating averages in the deck.
Questions people ask about digital pr link building
Is digital PR link building against Google's guidelines?
Earning coverage through genuinely newsworthy work is not. Paying for placement is: Google's spam policies name buying or selling links for ranking purposes, and articles or guest posts distributed at scale with links back, as link spam. The distinguishing question is whether the publication would have run the story without payment.
Do paid placements have to be marked?
Yes. Google's guidance on qualifying outbound links says advertisements and paid placements should carry rel sponsored, and rel nofollow indicates a site does not want to pass ranking credit. Marking removes the ranking benefit a link seller is charging for, which is why sellers resist it.
How many links should a campaign produce?
There is no defensible number, and an agency quoting one per month is describing a purchasing pipeline rather than a press campaign. Judge on the quality of the coverage, whether the outlets are ones your customers read, and whether the story would have been worth pitching with no link at all.
What if we already bought links?
Get the full list first, including anchor text and dates. Where placements were paid, ask for them to be marked with rel sponsored or removed. Google's spam policies say violating sites may rank lower or not appear in results, so treat cleanup as urgent rather than optional, and keep the record of what was done.
