Backlinko analyzed 11.8 million Google search results and found the #1 result has, on average, 3.8x more backlinks than positions 2 through 10. Links remain one of the strongest correlates of ranking — which is why an entire industry sells them, and why most of that industry is not worth your money.
Every "best link building services" list you'll find ranks vendors. This one ranks fits — because the honest answer is that the best service depends on whether you need someone to think for you, produce for you, or supply you, and those are three different products at three different price structures. Buy the wrong model and even a good vendor disappoints.
This guide covers the five service types, the three business models that sell them, what each realistically costs, what links can and cannot fix, and the exact questions that expose a weak vendor in a single email — including the scenarios where Bazsy is the wrong pick.
The five types of link building services
Before you compare vendors, get clear on what you're actually buying. Every service is some combination of these five formats.
1. Guest posting. A new article written for a third-party site, containing your link. The most controllable format: you choose the target page, the anchor, and the surrounding context. Full breakdown in our guest posting service guide.
2. Link insertions (niche edits). Your link added to an existing article that already ranks and already has authority. Often faster to show impact than guest posts because the host page has age and equity — but only when the page is genuinely relevant. We compare the two head-to-head in the guest post versus link insertion guide.
3. Homepage links. A link from a site's homepage, typically its strongest page. High impact, higher cost, and worth it only from sites with real traffic.
4. Digital PR. Campaigns — data studies, expert commentary, newsjacking — designed to earn coverage from journalists. The links are excellent and unpaid; the retainers ($3,000–$10,000+/month) and hit rates are not for everyone.
5. Expert-quote platforms (HARO-style). Responding to journalist requests for sources. Cheap, legitimate, slow, and unpredictable — a supplement, not a strategy.
Most businesses get the best cost-per-result from a mix of guest posts and link insertions on vetted, real-traffic publishers, which is what the Bazsy marketplace is built around.
The three service models
Those formats are sold through three business models. This is the choice that actually determines your experience and your bill.
1. Managed agencies. You buy strategy plus execution: an agency audits your site, picks targets, prospects, writes, and reports. Loganix and similar full-service shops anchor this category; Siege Media represents the content-led/digital-PR end of it. Retainers typically start around $2,000–$3,000/month and scale well past $10,000. The value is the thinking; the risk is opacity — some agencies show every placement for approval, others deliver a monthly PDF. Only work with the first kind.
2. Productized services. Fixed packages — "X links at Y tier for $Z" — ordered like SKUs. The HOTH and FATJOE built the category, FATJOE largely serving agencies white-labeling the work. Fast, predictable, minimal onboarding. The trade-off: packages are built for repeatability, not for your specific SERP, and site quality within a tier can vary order to order.
3. Marketplaces. Self-serve inventory: browse actual sites with actual metrics, pick placements, pay per link. Adsy, PRPosting, and Legiit operate here at various vetting standards; Bazsy is our entry in this category. Maximum transparency and control, no retainer — the trade-off historically was that you had to be the strategist doing the picking.
That last trade-off is what we built Optix to remove: it reads your domain, matches sites by niche rather than raw DR, and assembles the campaign — marketplace pricing with the site-selection thinking included. Combined with vetting (every listing shows 12-month traffic data, DR/DA, spam score, language, and do-follow status; no PBNs) and live link monitoring with a re-do-or-refund policy, that's the honest pitch. Judge it against the checklist below like everyone else.
Here's the same three models side by side:
| Managed agency | Productized service | Marketplace | |
|---|---|---|---|
| You supply | Goals and access | Target page, keyword | Strategy (or let Optix) |
| They supply | Strategy + execution | Fixed-tier fulfillment | Vetted inventory |
| Typical cost | $2k–$10k+/mo retainer | Per-package | Per placement, from $50 |
| See sites first? | Sometimes | Rarely (tier only) | Always |
| Best when | No SEO owner, high stakes | Volume, predictability | Control, no lock-in |
| Weakness | Opacity, cost | Generic targeting | You do the picking |
Which model fits you
Choose a managed agency if you have $3,000+/month, no internal SEO owner, and competitive head terms where strategy errors are expensive. You're paying for judgment; verify you'll get transparency with it.
Choose a productized service if you're an agency reselling link building at volume, or you need predictable fulfillment more than SERP-specific targeting.
Choose a marketplace if you (or your SEO) want to see and approve every site before paying, buy exactly what each month needs, and avoid retainer lock-in. This is also the only model where pricing is fully transparent before commitment.
And honestly, when Bazsy isn't the fit: if you need a full digital PR program — data studies pitched to journalists for earned coverage — that's agency work, and a marketplace placement is the wrong tool. Same if you have no localized pages, no target list, and no owner internally and you're unwilling to let an AI orchestrator do that assembly: buy strategy first, links second.
A worked example: the same budget, three ways
Numbers below are illustrative, but the ratios track what teams actually experience. Say you have $2,000 for the month and want links to a DR 35 SaaS blog.
- Agency: a $2,000 retainer is usually the floor, and much of month one is onboarding and strategy. Realistic first-month output: 2–4 placements plus a documented target list. You're buying the plan as much as the links.
- Productized: $2,000 buys a mid-tier package of perhaps 5–8 links on tier-defined sites. Fast, but you approve the tier, not the individual URLs.
- Marketplace: $2,000 at a $50–$250 per-placement range buys roughly 8–20 links you hand-pick, each with its traffic and relevance visible before you spend a cent.
The marketplace wins on raw link count and transparency; the agency wins when you don't yet know which links to buy. That difference — thinking versus supply — is the whole decision. Optix exists to give a marketplace buyer the agency's targeting without the agency's retainer.
What links fix — and what they don't
This is the part most vendors skip, so here it is plainly.
Links fix: authority deficits. If competitors outrank you with comparable content because their domains and pages have stronger link profiles, links close that gap. This is the majority of competitive B2B and e-commerce SERPs.
Links do not fix:
- Thin or mistargeted content. Ahrefs' data shows only 1.74% of newly published pages reach the top 10 within a year — and content that doesn't match search intent stays in the other 98% regardless of links.
- Technical problems. Unindexed pages can't rank. No link changes that.
- A wrong offer. Links bring qualified attention to a page. If the page doesn't convert, you've bought traffic to a leak.
Any link building service that promises rankings without asking what page you're pointing at, and why it deserves to rank, is selling activity rather than outcomes. A quick self-test before you spend: open the page you want to boost, search its primary keyword, and read the three URLs currently ranking. If they are visibly more thorough, more current, or better matched to the query than your page, links are premature — fix the page first, then build to it.
Honest pricing benchmarks
| Service type | Typical market range | Notes |
|---|---|---|
| Guest post (real publisher) | $80–$600 per placement | Scales with the site's traffic and authority |
| Link insertion | $60–$500 per link | Cheaper than guest posts at the same tier |
| Homepage link | $200–$2,000 | Priced on the site's strength |
| Digital PR | $3,000–$10,000+/mo | Retainer-based, no guaranteed volume |
| "Bulk backlink" packages | $5–$50 per link | Don't. See below. |
Two pricing red flags: anything priced per-link in double digits at claimed high authority, and anyone who won't show you the exact site before you pay. On Bazsy, every listing shows the publisher's DR, DA, 12-month organic traffic, country split, and whether the link is do-follow — before you order, from $50 per placement. The full model, tier by tier, is in our link building pricing breakdown.
Why the "cheap" link is the expensive one
Consider two ways to spend $500. Option A: ten $50 links from a bulk vendor who won't name the sites — in practice, a private blog network where the same footprint links to hundreds of unrelated clients. Option B: two $250 placements on niche-relevant sites with visible, verifiable organic traffic.
Option A's real cost isn't $500; it's $500 plus the cleanup. When those footprints get devalued or your profile trips a spam signal, you're paying again — this time for a disavow file and months of lost momentum. Option B's two links compound quietly and never need undoing. The industry's oldest lesson is that cost-per-link and cost-per-result move in opposite directions past a certain point.
How to evaluate any link building service — in one email
Ask a prospective vendor these questions. The answers do the vetting for you, and they work on any model, including us.
- "Can I see the exact sites before I pay?" — Anything but "yes" is disqualifying. Exact URLs, not "DR 50+ sites in our network."
- "What organic traffic do your placement sites have, and how do you verify it?" — The answer should reference third-party data (Ahrefs, Semrush), not a proprietary score you can't check. The same publisher vetting standards you'd apply yourself apply to whoever you hire, because you inherit their bar.
- "Can I read three recent placed articles?" — If you wouldn't publish them under your own name, neither should your money.
- "What happens if a link goes down in 90 days?" — You want a monitoring and replacement policy in writing. Bazsy monitors every link live and re-does or refunds placements that don't meet the listing.
- "Will you tell me if link building is the wrong move for a given page?" — A vendor with no scenario where they'd decline your money is not giving you advice; they're processing orders.
- "How do you handle sponsored-link disclosure?" — They should speak fluently about Google's link spam policies and outbound link qualification. If
rel="sponsored"draws a blank, walk.

Red flags that end the conversation
Guaranteed rankings. Payment before site reveal. Prices that make real editorial impossible (a genuine article on a genuine site cannot cost $25 — the math is covered in the pricing breakdown). "Unlimited" anything. Turnaround measured in hours rather than days, which almost always means auto-generated content on a network rather than a real editor accepting a real pitch. A metrics sheet that leads with Domain Authority but goes quiet on organic traffic — DR and DA are modelled scores that can be inflated; traffic is the number that's hard to fake. And any vendor whose own site ranks for nothing — people selling rankings should have some.
One differentiator almost nobody offers
Whatever model you choose, ask one more question: "Can you place links in German, Spanish, or Portuguese?" Nearly every service on every list is English-only, while non-English SERPs offer the same authority at a fraction of the competition and cost. It's Bazsy's structural edge — 100k+ vetted sites filterable by country and content language — and the full case is in our guide to multilingual link building. Even if you don't buy from us, buy from someone who can answer that question.
Agency, marketplace, or in-house?
If you're weighing doing it yourself: in-house outreach gives maximum control at maximum time cost; expect 10–20 hours per earned link when starting out, between prospecting, qualifying, pitching, and following up. Agencies fold that labor into a retainer and add strategy. Marketplaces remove the prospecting and negotiation entirely and sell the vetted inventory directly.
Bazsy is the third model, with one addition: Optix, an AI orchestrator that reads your domain, builds the target list by niche rather than raw DR, and assembles the campaign — so the marketplace works even if you don't have an SEO team picking the sites. If you're comparing paid-link approaches specifically, our guide to buying backlinks without torching your domain covers the risk spectrum vendor by vendor.

How long before links move rankings?
The question every buyer asks and few vendors answer honestly: not next week. A newly placed link has to be crawled, the host page reassessed, and the equity attributed — and Google applies that slowly and unevenly. As a rough field guide, not a guarantee:
- Weeks 1–4: the link is discovered and indexed. Often no visible movement at all. This is normal and not a sign the link failed.
- Weeks 4–12: if the target page was already close (say, ranking 8–15 for a query it genuinely deserves), this is where a relevant link tends to show — a few positions, sometimes a page-one break.
- Months 3–6: the compounding window. A steady handful of relevant links per month, pointed at pages that deserve to rank, is what moves competitive terms. One-off link buys rarely do.
Two implications follow. First, judge a service on a 90-day horizon minimum; anyone promising week-two results is selling a story. Second, consistency beats bursts — five relevant links a month for six months outperforms thirty links dumped in one, both for ranking effect and for looking like a profile a real brand earned. If a page shows no movement after a genuinely relevant link and three-plus months, the bottleneck is almost always the page or the intent match, not the link count.
The bottom line
The best link building service is the one whose model matches your team, whose inventory you can inspect before paying, and who will tell you when not to spend. You're not really paying for links — you're paying for verified publisher quality, relevance matching, content the publisher will accept, and links that stay live. Everything else is a spreadsheet of URLs. Price the thinking and the links separately, and never buy either sight unseen.
