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.
This guide maps the five types of link building services, what each realistically costs, what links can and cannot fix, and the questions that expose a bad vendor in one email.
The five types of link building services
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.
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.
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.
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.
How to evaluate a link building service in one email
Ask a prospective vendor these five questions. The answers do the vetting for you.
- "Can I see the exact sites before I pay?" — Anything but "yes" is disqualifying.
- "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.
- "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 at minimum know what Google's outbound link qualification guidelines say. If the term rel="sponsored" draws a blank, walk.

Agency, marketplace, or in-house?
Agencies bundle strategy with execution — good when you have budget ($2k–$10k+/month) and no internal SEO. In-house outreach gives maximum control at maximum time cost; expect 10–20 hours per earned link when starting out. Marketplaces sit between: you (or your SEO) keep the strategy, and the marketplace supplies vetted inventory, content, and delivery per placement — no retainer.
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 for you — 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.

The bottom line
You're not paying a link building service 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.
