An off page SEO agency sells everything that happens away from your own website: links from other sites, mentions in press and industry publications, profile and citation consistency, and the reputation signals that make a brand look established. It is the part of search most exposed to bad practice, because the easiest version of the job is buying links and the easiest version of the pitch is a monthly quota. This guide explains what off page work legitimately contains, which tactics sit clearly outside Google's policies, what a defensible programme costs, and the questions that reveal which kind of provider you are talking to.
What off page work legitimately contains
Four workstreams do the honest version of this job. Digital PR: creating something worth referencing (original data, a useful tool, a genuinely newsworthy story) and pitching it to journalists and industry publications, which produces links as a by-product of coverage. Relationship and partnership links: suppliers, trade bodies, sponsorships, universities, the associations your business already belongs to. Unlinked mention reclamation: finding places your brand is named without a link and asking. And entity consistency: profiles, citations and structured data that make it unambiguous which business you are, which matters for local visibility. Notice what is absent from that list: monthly quotas of guest posts on sites that exist to sell them, private blog networks, and paid placements dressed as editorial. Those are the cheap version, and they are cheap because the risk transfers to you.
Where the line is, in Google's own words
Google's spam policies address link spam directly, treating links intended to manipulate rankings as a violation, and they name the patterns: buying or selling links that pass ranking signals, excessive link exchanges, large-scale article campaigns with keyword-rich anchor text, automated link generation and low-quality directory submissions. The policies also cover paid placements more broadly, with the expectation that sponsored or paid links are marked so they do not pass ranking signals. The practical test for a buyer is straightforward: if a link would not exist had money not changed hands, and it is not marked as paid, it is on the wrong side of the line. Ask any prospective agency to state its position on paid links in writing. An honest firm will say it does not buy them or will disclose exactly where it does and why, and either answer is more useful than a vague reassurance about white hat methods.
What it costs and how it is priced
Off page programmes are usually priced as a monthly retainer, occasionally per campaign, and rarely per link once you are above the link-selling end of the market, because per-link pricing is essentially an admission of how the links are obtained. The cost drivers are the seniority of the people doing outreach, whether original research or asset creation is included, the competitiveness of your sector, and the target publication tier, since a placement in a national title takes far more work than a niche blog. Expect a defensible programme to be slower and more expensive than a quota-based one, and expect it to produce fewer links. That is the trade you are making. Judge it on whether the links come from places a customer might plausibly read, not on a count or on a third-party authority score, which is a tool vendor's estimate rather than a Google signal.
Vetting, and how it pairs with on-site work
Ask for recent placements with live URLs and check them: does the site have real readership, real editorial staff and content unrelated to link selling? Ask what percentage of last quarter's links came from paid placements. Ask how they choose anchor text, since heavy exact-match anchors are one of the patterns the spam policies name. Ask what they would do if a client was hit by a manual action, because a firm that has managed one has a real process and a firm that has not may not understand the exposure. Finally, remember that off page work multiplies on-site quality rather than replacing it: links pointing at pages that do not answer the query buy you visibility for something the reader will bounce from. Most buyers get better returns fixing the on-page and technical foundation first, then funding authority work once the pages are worth ranking.
Questions people ask about off page seo agency
Is buying links ever safe?
Buying links that pass ranking signals is a stated violation of Google's spam policies, and the site that receives them carries the risk, not the agency that placed them. Paid placements are acceptable when they are marked so they do not pass ranking signals, which is exactly what most link sellers will not do.
How many links per month should we expect?
A count is the wrong unit. A quota can be met by any provider willing to buy, so it measures spending rather than authority. Ask instead to see the last quarter's placements as live URLs and judge whether those publications have readers. Quality-led programmes routinely produce a handful of links a month, not dozens.
Do domain authority scores matter?
They are third-party estimates from tool vendors, not signals Google publishes or uses. They are a useful rough filter and a poor target, and optimising for them attracts exactly the sites that game them. Relevance and genuine readership are the better test.
Should we do off page or on page work first?
On page and technical first, in almost every case. Links amplify pages, so amplifying a page that does not answer its query wastes the spend. Once your target pages are genuinely the best answer available, authority work is what closes the gap against established competitors.
