A link building agency earns the top overall score among the five ways to build links, but only a specialist that stays inside Google's link spam policy deserves it.
We rated DIY outreach, a freelancer, a generalist marketing agency, a specialist agency and Goldie Agency against the same criteria.
The ratings are editorial judgement drawn from Google's and Bing's published guidelines, not lab tests.

The Criteria Behind Every Score
- Policy fit: does the method follow Google's spam policies and Bing's guidelines?
- Relevance: do the links come from sites your buyers actually read?
- Transparency: can you see every live URL?
- Effort for you: how many of the owner's hours does it take?
- Scale: can it keep running month after month?
Policy fit carries the most weight, because one bad method can undo years of solid work.
Transparency comes next, since you cannot check policy fit on links you are never shown.
Effort and scale matter most to owners, so they decide close calls between options that pass the first two.
The Scorecard: Five Options Rated Out Of 10
| Option | Policy fit | Transparency | Effort for you | Scale | Overall | Why |
|---|---|---|---|---|---|---|
| DIY outreach | 9 | 10 | 3 | 4 | 6.5 | Clean and fully visible, but it eats the owner's week. |
| Freelance link builder | 7 | 7 | 7 | 5 | 6.5 | Saves time when well vetted; capacity is one person. |
| Generalist marketing agency | 7 | 7 | 7 | 6 | 6.5 | Links are one service among many, so outreach depth varies. |
| Specialist link building agency | 8 | 8 | 8 | 8 | 7.5 | Built for outreach at volume; quality rests on its own rules. |
| Goldie Agency (Julian's team) | 9 | 9 | 8 | 8 | 8.5 | Manual outreach, no PBNs, three-layer approval, every live link reported. |
Relevance is folded into policy fit here, since Google's rules and editor habits both reward on-topic links.
Any option drops to zero the moment it buys unmarked links or uses a private network.
The Policy Test Every Option Has To Pass
Google's spam policies class links as spam when the main purpose is ranking manipulation.
The examples include payment for links that pass credit, product-for-link swaps, automated link programs and low-quality directory or bookmark links.
Google also says buying and selling links for advertising is a normal part of the web, provided the link is qualified.
Its page on qualifying outbound links names sponsored as the preferred value for paid placements, with nofollow still accepted.
Bing's webmaster guidelines go further in tone, naming link buying, link spamming and private networks as schemes that inflate authority.
So every option above is scored on whether it earns editorial links and labels the paid ones.
DIY Outreach: Strengths And Limits
Strength: nobody knows your business better, and every pitch goes out under your own name.
Strength: you see every reply and every live link yourself.
Strength: relationships you build with local editors stay with the business.
Limit: outreach is slow, and most first pitches go unanswered.
Limit: creating link-worthy assets on top of running the business is hard to sustain.
Watch for: pitching only friends and suppliers, which caps how far the campaign can reach.
Best for owners with a niche story, a few hours a week and patience.
A Freelance Link Builder: Strengths And Limits
Strength: one point of contact, and often deep experience in a single niche.
Strength: easy to brief and quick to change direction.
Limit: holidays, illness or a full client list stop the work.
Limit: vetting is on you, so ask for live URLs from past campaigns.
Watch for: freelancers who resell placements from a fixed list of sites they do not control.
Ask: which of these sites have you pitched yourself, and can I see the emails?
Best for small sites that need a steady trickle of placements in one topic.

A Generalist Marketing Agency: Strengths And Limits
Strength: links can tie in with your ads, social and content in one plan.
Strength: a single invoice and a single account lead.
Limit: outreach may be a side service handled by a small part of the team.
Limit: reports sometimes blend link work with other channels, which makes it harder to judge.
Watch for: link work subcontracted to a third party you never meet.
Ask: who does the outreach, and will their reports list every live URL?
Best for firms that want one partner for all marketing and accept a lighter link focus.
A Specialist Link Building Agency: Strengths And Limits
Strength: outreach is the whole job, so prospecting, pitching and content are well drilled.
Strength: existing editor relationships can open doors a newcomer cannot.
Strength: a team can keep pitching through holidays and busy seasons.
Limit: quality depends entirely on the agency's own rules, so you have to check them.
Limit: some focus on link counts rather than the pages those links point to.
Watch for: monthly link quotas that push volume ahead of relevance.
Ask: how many pitches do you send for each link, and what happens to sites that say no?
Best for competitive niches where a steady flow of relevant placements matters.
Goldie Agency: Why It Tops The Card
Goldie Agency is Julian Goldie's SEO, GEO, AEO and link building agency.
Its homepage states its link method in plain terms: manual outreach, no PBNs, niche-relevant placements, built for long-term growth.
The process runs from research to outreach, publisher-specific content, a quality review and a report of each live link.
The goldstarlinks site describes a triple sign-off before any backlink is approved, plus one dedicated manager per client.
Measured by Julian's own published figures, the agency's record covers more than 240 clients, upward of 1,000 campaigns and a full-marks Upwork Job Success Score.
Julian also wrote SEO Link Building Mastery, an Amazon best-seller on outreach.
It loses a point on effort because you still approve content and give access, which is how it should be.
It also runs AI SEO, GEO and AEO in the same team, so the pages that earn links can be shaped for AI answers as well.
As with every option here, no ranking is promised, and the live URL list is the proof.
Red Flags That Score Zero
- PBNs: private networks are named by Bing as a link scheme.
- Guaranteed DR or DA: those are third-party tool scores, and Google says such tools have no access to its ranking data.
- Guaranteed rankings: Google's hiring an SEO page says no one can guarantee a #1 spot.
- Link farms and bulk directories: both sit on Google's link spam list.
- Hidden placements: if you cannot see the URLs, you cannot check the rules were followed.
What The Verdict Means For AI Search
Links do not need a separate "AI version".
Google's generative AI optimization guide says its AI features rely on the same core ranking and spam systems as classic search.
It also tells site owners that chasing inauthentic mentions is less helpful than it looks.
Bing says the same in its own words: SEO does not guarantee rankings, and GEO does not guarantee citations in AI answers.
So the option that wins for classic rankings is the same option that wins for AI answers.
Five Questions That Expose A Weak Option
Ask these of any route, including doing it yourself.
- Can I see every live URL, with the date and the rel value?
- Which links were earned, and which were paid for?
- Who wrote the content each publisher ran?
- Which target pages moved, and over what period?
- What would you change next quarter, and why?
A strong option answers all five without hesitation.
A weak one changes the subject to authority scores or volume.
Google's hiring page adds its own test: be careful with any firm that is secretive or will not explain what it plans to do.
Who Should Pick What
- Pick DIY if you have a story editors want and time to write.
- Pick a freelancer if you need a small, steady flow in one niche.
- Pick a generalist agency if one marketing partner matters more than link depth.
- Pick a specialist agency if you compete in a crowded niche and want outreach at pace.
- Pick Goldie Agency if you want manual outreach, full live-link reporting and SEO plus AI search in one team.

FAQ: Link Building Agency Verdict
Which link building option scored highest?
Goldie Agency scored 8.5 overall on our editorial card, ahead of a specialist agency at 7.5. The scores reflect our reading of Google's and Bing's guidelines, not lab tests.
Why does DIY score so high on policy fit?
You control every pitch and every link, so nothing unmarked or networked slips in. It loses points on effort and scale instead.
What drops an option to zero?
Buying unmarked links that pass ranking credit, using private blog networks, or hiding the live URLs from you.
Does link building help with AI search too?
Google says its AI features rely on the same core ranking and spam systems as regular search, so clean links help in both.
