Choosing a link building company is not about finding the longest list of services or the lowest price per link. It is about finding a company whose links you would be comfortable showing to a customer, an editor, or a search engine reviewer. This guide gives you a way to vet a provider before you sign, with questions you can ask on a sales call, a checklist for the monthly report, and red flags that should make you walk away.

Start with the model, not the price

Link building services are usually sold in one of a few models. Each model fits a different kind of buyer, and the wrong model can waste months even if the company itself is honest.

Model How it usually works Best fit Main risk to check
Per link You pay for each placement, often after approval A buyer who wants control over each site Sites may be recycled across many clients
Monthly retainer A fixed monthly scope: outreach, content, and a target number of links A buyer who wants steady, ongoing work Scope can drift if reporting is vague
Digital PR Original research, data, or stories pitched to news and trade press A buyer who wants brand coverage as well as links Slower, and results are less predictable month to month
Marketplace or fulfilment You order placements from a list, often for agencies An agency that needs fulfilment at scale Quality varies widely by site on the list

Ask the provider which model they are actually selling, and what happens if a link is removed, a site changes hands, or a placement never goes live. A clear answer to those three questions tells you more than a glossy sales page.

What a trustworthy company should show you

Before you pay, ask for evidence you can check yourself. A company that is proud of its work should not struggle with these requests.

  1. Recent live placements, not just a portfolio page. Ask for links that went live recently, on real sites, that you can open and read. Check whether the article reads like real editorial content, or like a thin article built only to hold a link.
  2. Sites with real traffic and a real topic. Open the linking site. Does it publish regularly? Does it have an audience that matches your topic? A site with no visible readership and no clear topic is a warning sign, even if a tool gives it a high score.
  3. A clear explanation of how outreach works. Who writes the pitch? Who writes the article? Do you approve sites before placement? If the answer is “we handle everything, you do not need to see it”, that is not transparency, it is a black box.
  4. Anchor text control. Ask how anchor text is chosen, and whether you can reject an anchor that sounds forced or salesy. Natural anchor text protects your site far better than a set of exact match phrases.
  5. A replacement policy in writing. Links get removed, sites close, and pages get redesigned. Ask what happens then: is the link replaced, is it refunded, or is it simply gone? Get the answer in the agreement, not just on a call.

If a provider cannot show recent live work, cannot explain its process, or will not put its replacement policy in writing, treat that as a serious warning, even if the price looks attractive.

Questions that expose a recycled site list

Some providers sell the same set of sites to every client in every niche. That is how a link that looks fine on its own can still be weak: it sits on a site that links to hundreds of unrelated businesses.

Use these questions on a sales call:

A good provider will answer directly, and may even tell you about a site they decided not to use. A weak provider will change the subject, or answer with a general claim about quality without naming a single site.

How to judge link quality on the call

You do not need a tool subscription to judge a link. Open the example placements and ask yourself:

If the answer to the first two questions is no, the link is not worth buying, whatever the metrics say. Metrics can help you compare sites, but they cannot replace reading the page.

White hat link building, and why it matters when you hire

White hat link building, when a company uses the term honestly, means links earned through outreach, editorial content, and digital PR, following search engine guidelines. It does not mean links that are simply labelled white hat on a sales page.

Ask the provider to explain, in plain terms, how each link is earned. If the explanation involves paying a site owner for a followed link purely to pass ranking value, that is not white hat work, whatever the label says. Paid links meant to pass ranking value should carry the proper sponsored or nofollow marking, and a provider that hides that distinction is putting your site at risk.

This matters because a penalty, or a quiet loss of trust, is far more expensive than a slightly higher monthly fee for clean work. A company that is honest about what it will not do is often safer than a company that promises everything.

Monthly SEO services: what the report should contain

If you buy link building as part of monthly SEO services, the monthly report is where trust is built or lost. A useful report should let you answer, in five minutes, what was done, what went live, and what happens next.

A report worth paying for includes:

A report that only shows a total link count, a chart going up, and a list of domain scores is not enough. You cannot check a count, and you cannot learn from a chart. Insist on live links you can open.

Also ask who does the work. Some companies sell the service and outsource the outreach to another team. That is not automatically bad, but you should know who is writing pitches in your name, and you should be able to raise quality concerns with the company you are paying.

Pricing: how to compare without being misled

Link building prices vary widely, and the same price can buy very different things. A low price per link often means a thin article on a low quality site, a site that sells links to everyone, or a placement that will not last. A high price does not automatically mean quality either.

Compare providers on the same basis:

Do not compare a per link price from one provider with a monthly retainer from another without breaking both down into the same pieces: how many links, on what kind of sites, with what approval and replacement terms. Once you compare like with like, the cheapest option often stops looking cheap.

Red flags: walk away if you see these

Any one of these on its own is a reason to ask harder questions. Two or more together are a reason to walk away, even if the sales call felt friendly.

A shortlist process you can use this week

Day 1: Write down your goal in one sentence. For example: earn relevant links to your main service page from sites your customers actually read.

Day 2: Shortlist three providers, and ask each for recent live placements and a written replacement policy.

Day 3: Open the example placements yourself, and run the link quality checks above.

Day 4: Ask the recycled site list questions, and ask what the first month’s report will look like.

Day 5: Choose the provider whose work you would be happy to show a customer, not just the provider with the lowest price or the longest list.

That process takes less than a week, and it protects a budget that could otherwise be spent on links that quietly hurt you.

Frequently asked questions

Should I hire a link building company, or do it myself?

It depends on time, skill, and budget. Doing it yourself gives you full control and lower cash cost, but it takes many hours of outreach. Hiring a company saves time, but only pays off if the company is transparent, shows live work, and lets you approve sites.

What is the difference between a link building company and a link building agency?

In practice, very little. Both terms are used for companies that sell link building services. Judge the provider by its live placements, process, reporting, and replacement policy, not by whether it calls itself a company or an agency.

How many links per month should I expect?

There is no safe universal number. A small number of relevant, durable links beats a large number of weak links. Ask the provider what it can realistically deliver in your niche, with site approval, and be wary of a large monthly target that is promised before any outreach.

Do I need to approve every site before placement?

Site approval is strongly recommended, especially at the start. It lets you reject sites that do not fit your brand, and it forces the provider to show its work. If a provider refuses any approval, ask why, and consider whether that level of control is acceptable to you.

What should I do if a provider’s links are removed?

Check the agreement first. A clear replacement policy should say whether the link will be replaced, and within what time. If there is no policy, raise it in writing, and use the experience when you review the provider at the end of the contract.

Is monthly link building better than a one off campaign?

Monthly work suits a site that needs steady authority building over time. A one off campaign suits a specific launch or a single page that needs a push. The better choice is the one that matches your goal, not the one the provider prefers to sell.
