Choosing a link-building agency is one of the highest-stakes decisions a marketing lead makes, and one of the hardest to get right. The damage from picking badly isn't just wasted budget — bought links from a PBN can suppress your rankings for 6–12 months after you've severed the relationship. Picking well, on the other hand, can move money pages from page 4 to page 1 within a quarter.
This guide gives you the full buyer's checklist: what to ask, what answers to accept, the red flags that should end a sales call, and what fair pricing looks like in 2026.
Start with the question that disqualifies most agencies
Before you book any sales calls, ask one thing in your first email or LinkedIn message:
"Can you send me three live URLs of placements you've delivered for clients in the last six months — including the publication name, your client's brand name visible in the article, and the live link?"
This single question filters out around 70% of UK link-building agencies on its own. Many "agencies" are in fact resellers buying from a single backend supplier, with no real placements they can show without exposing the supply chain. Others run PBN networks they can't disclose. The agencies who can produce three real, live, named-client URLs in 24 hours are the agencies worth your time.
What to ask on the sales call
Assuming an agency clears the first filter, here are the seven questions that separate real operators from sales theatre.
1. "Show me your three most recent placements — live URLs, not screenshots"
Same as before, but in higher resolution. Open each link in front of them on the call. Confirm:
- The article is real, indexed by Google, and dated within the last 90 days
- The publication shows in Ahrefs / Semrush as having real organic traffic (not just high DR)
- The link to the client's site is dofollow (or, on tier-1 publications, that the client's brand is named in-context even if the link is nofollow)
- The article reads like editorial content, not a press release pasted onto someone's blog
2. "What's your anchor text policy?"
The right answer involves percentages. A real agency will tell you something like: "We aim for around 55% branded anchors, 25% partial-match commercial, 15% naked URLs and 5% generic." If they say "we let the journalist decide" — that means they don't have a policy and they'll over-optimise.
3. "What happens if a link gets removed in six months?"
Real editorial placements rarely drop because they sit inside articles a journalist actually wrote. Ask what an agency does when a link does come down — do they monitor placements, do they work with you to source another, or is it your problem to chase. Anyone offering a blanket "12-month replacement guarantee" is usually offsetting cheap PBN inventory where drops are baked into the model.
4. "Will you white-label these placements or are they yours?"
Some agencies market themselves directly while quietly reselling from a single bulk-link supplier. If you ask whether the placements are theirs or sourced from a third party and they get evasive, you're paying retail for a wholesale link. Worse, your competitor down the road may be buying the same link from the same supplier next month.
5. "What's your monthly capacity?"
An agency that can place 200 PR backlinks per month for a single new client is either lying or running a link farm. Real journalist relationships are the bottleneck — most reputable agencies cap individual client output at 15–25 high-quality placements per month, and many won't take on more than 30–50 clients total because beyond that the relationships dilute.
6. "Can I speak to two current clients?"
Real agencies say yes (with the clients' permission) within 48 hours. The clients should be reachable, contactable on LinkedIn, and willing to talk for 15 minutes. If you only ever get vague "we don't share client details" responses, the references probably don't exist.
7. "What does month one actually look like?"
The right answer mentions: kickoff call, competitor backlink audit (delivered as a written brief by week 1), anchor text plan signed off by week 2, first pitches by week 2–3, first placements landing weeks 4–6. If the answer is "we just start placing links" — they're using PBNs (no real outreach happens that fast) or they don't have a process.
The five red flags that should end a sales call
- "Guaranteed Forbes / BBC / Bloomberg placement." No agency can promise this; the journalists at those publications make the decisions, not link sellers. Anyone claiming a guarantee is selling you an old-school "Forbes Contributor" account (now devalued by Google) or planning to use a PBN domain that mimics the brand.
- Prices below £200 per "DR 70+" link. Real outreach + journalist relationship management + writer fees alone cost more than that. The economics don't work; the link is from a PBN.
- "DR 80+ from £150" packages. Same problem. Real DR 80+ publications charge £600–£1,200 per placement, on the rare occasions they accept paid editorial at all.
- Long contracts demanded upfront. Reputable agencies sell month-to-month. If you're being asked to lock in for 6 or 12 months before you've seen any work, you're being trapped before verification.
- "Set and forget" pitches. Anyone telling you link building is a one-time campaign is selling a product, not a service. Sustainable rankings require sustained work.
What fair pricing looks like in 2026
| Service tier | Monthly retainer | What you should get |
|---|---|---|
| Entry-level (small business, single product) | £1,500–£2,500 | 2–4 PR backlinks/month at DA 60–75, monthly report, email support |
| Growth (mid-market, multiple money pages) | £3,000–£5,000 | 5–8 PR backlinks/month at DA 70+, dedicated strategist, Slack channel, monthly call |
| Authority (category leader, defending position) | £6,000–£15,000+ | 10+ tier-1 PR backlinks (DA 80+), digital PR campaigns quarterly, dedicated team, white-label reporting if needed |
| Enterprise (white-label / agency reseller) | £15,000+ | Custom mix, dedicated account team, SLA, full white-label dashboard |
For UK-specific context: London-based agencies typically price at the higher end of these ranges. Regional agencies (Manchester, Bristol, Edinburgh) often deliver the same quality at 15–25% lower retainer fees because their cost base is lower.
The three contract terms that matter most
Before you sign anything, the contract should explicitly address:
- Drop policy: What happens if a link comes down. Real editorial placements rarely drop, but the agency should monitor your placements and have a written policy on how they handle removals — replacement, refund, or simply notification.
- Cancellation terms: 30-day notice maximum. Any links already in the production pipeline complete and ship to you with no clawback.
- Reporting deliverables: Live placement URLs, screenshots, DA at time of placement, indexed status, and a monthly PDF report. All of this should be in writing.
Common myths buyers fall for
"More links is always better." Wrong. Ten links from real publications outperform a thousand links from PBNs. Volume divorced from quality is meaningless and frequently harmful.
"DR is the most important metric." Half right. DR matters, but DR + organic traffic + content quality is the actual signal. A site with DR 90 and 200 monthly visits is a manipulated metric — Google can tell, and a link from there does nothing.
"My agency should just handle it — I don't need to see anything." The opposite. The best agencies are the most transparent: every placement, every screenshot, every live URL, in your dashboard, every week. Black-box "trust us" agencies are usually hiding something worth seeing.
"Once I've ranked, I can stop." Rankings drift back. Competitors continue investing. Stopping link building when you reach page 1 is the most common reason brands lose hard-won rankings within two quarters.
The 30-second summary
- Filter agencies first by asking for three live placement URLs from the last 6 months
- Demand a written anchor text policy, a clear drop/replacement policy, and month-to-month terms
- Real DR 80+ links cost £600–£1,200 each — anything below £200 is a PBN
- Cap your expectations at 5–25 high-quality placements per month; anyone promising 100+ is link-farming
- No agency can guarantee specific tier-1 publications — anyone claiming they can is lying
- Ask for two reachable client references, talk to them for 15 minutes each
