A link building service earns references to a website from other publications. The work is research, outreach, and coverage: finding sites whose readers overlap with the business, and giving them a reason to cite it. The output is editorial links, meaning links a publisher chose to place rather than links a business paid to appear.
That distinction is the whole subject. Links that a publisher chooses carry the credit a search engine is willing to pass. Links bought for that credit are classified differently, and the difference is documented rather than a matter of opinion.
A link building service earns references, it does not buy them
The service does a specific set of things. All of them end in someone else deciding to publish a link, and none of them involve paying for that decision. A vendor who skips the persuasion step and goes straight to payment is selling a different product under the same name.
- Prospect research: finding outlets, journalists, and sites whose readers overlap with the business’s market.
- Outreach: contacting those people with a specific, relevant reason to reference the business.
- Asset creation: producing the thing worth citing, such as original data, a tool, or a substantive guide.
- Digital PR: pitching stories to publications that cover the sector.
- Reclamation: finding places where the business is already mentioned without a link, and asking for one.
Each of these has a set method, and each is a craft in its own right. The distinction between them and the practices Google prohibits is published, not inferred.
What the work consists of
The work above turns into a monthly workload with outputs that can be seen and checked. A service that cannot describe its process in these terms is usually buying placements rather than earning them. Bought placements require no process to describe, which is why vague answers about method are informative.
| Activity | What it produces | Where the method is set out |
|---|---|---|
| Prospecting and qualification | A list of target publications with a stated reason each would care | the link building strategy guide |
| Asset and story development | Something citable: data, research, or a resource that does not already exist | how digital PR earns coverage |
| Outreach and follow-up | Pitches sent, replies received, placements agreed or declined | The strategy guide, linked above |
| Mention reclamation | Existing unlinked references converted into links | The strategy guide, linked above |
| Profile monitoring | A record of links gained and lost over time | The backlink audit guide, linked in the FAQ below |
Why any of this produces a ranking benefit is covered in what backlinks are and why they count. What separates these activities from the practices that carry risk is a published line.
The line Google draws between earned links and link schemes
Google defines link spam as creating links primarily to manipulate search rankings. It publishes a list of practices that qualify (source: Google Search Central). The first item on that list is buying or selling links for ranking purposes. That includes exchanging money for links, or for posts that contain them.
| Practice | How Google’s policy classifies it |
|---|---|
| A publisher chooses to cite a business in its own article | An editorial link. Not a scheme. |
| Paying a site for a link that passes ranking credit | Named directly: “buying or selling links for ranking purposes” |
| Paying for an article that contains a credit-passing link | Named: advertorials or native advertising where payment is received for articles that include links that pass ranking credit |
| Sending a free product in exchange for a write-up and link | Named: “exchanging goods or services for links” |
| Automated tools that generate links at volume | Named: “using automated programs or services to create links to your site” |
| Publishing thin pages whose purpose is to carry links | Named: creating low-value content primarily to manipulate linking and ranking signals |
| A paid placement marked with rel=”sponsored” or rel=”nofollow” | Permitted. Google states it is not a violation to have such links when they are qualified this way. |
The final row is the part most vendor pages omit. Paid placement is not itself prohibited. Passing ranking credit through it is. A sponsorship marked with the correct attribute is a legitimate advertising purchase, judged on the audience it reaches rather than on ranking effect. The attributes themselves are covered in anchor text and link attributes. The full set of practices and their consequences is set out in the link schemes that trigger penalties.
A buyer who knows where the line sits can inspect what a vendor actually delivers.
What a real engagement delivers and reports
An earned-links engagement produces an auditable record, because every placement had to be argued for. The reporting is therefore specific about what was attempted, not only about what succeeded. A report consisting of a link count and a metric score describes an outcome without evidencing a process.
- Named placements with live URLs: every link, on a page that can be opened and read.
- The context of each link: the article it sits in, and why that publication covered the subject.
- The outreach record: how many publications were approached, and how many declined.
- Attribute disclosure: whether any placement was sponsored, and how it was marked.
- Losses as well as gains: links that disappeared when a page was rebuilt or removed.
Three things in a proposal warrant scrutiny. A guaranteed number of links per month implies placements that are already secured, which describes stock on hand rather than outreach. A price quoted per link prices the placement itself, which is the transaction Google’s policy names. A refusal to name target publications before work begins means the work cannot be checked until after it is paid for. Choosing a provider on evidence of this kind is covered in how to choose an SEO agency.
Deliverables matter only if the service is the right purchase to begin with.
When a Singapore business needs the service
Authority work becomes the binding constraint once the other levers are in place. Consider a site with sound technical foundations and content that answers its market’s questions. If it still sits below competitors, the gap is usually authority rather than coverage.
- The content gap is already closed: the pages exist and answer the queries, but rank below sites with longer histories.
- The category is contested: competitors are older firms with years of built-up references.
- The business has something citable: its own data, clinical know-how, or a real local specialism an outlet would want.
- The market reaches beyond the immediate neighborhood: island-wide or regional rivals, where being close by does not decide the result.
The Singapore market has a specific characteristic here. The pool of relevant local publications is small, so the same handful of outlets hear from every agency in the category. That raises the standard a pitch has to meet. Market-specific considerations are covered in link building in the Singapore market, and what the wider program costs in what an SEO program costs.
For a substantial number of sites, authority is not the constraint at all.
When a link building service is not what a site needs
Buying authority work before the conditions for it exist wastes the budget. In the cheap tier it also creates risk, because a low fee cannot fund genuine outreach. Four situations recur, and each has a different corrective action.
- Nothing on the site is worth citing: outreach needs a reason for a publication to link. Where no data, resource, or distinctive expertise exists, there is nothing to pitch, and the work stalls before it starts.
- Technical faults block indexing: authority passed to pages a search engine cannot crawl or index produces nothing. The fault is cleared first.
- The competing set ranks on coverage, not authority: where competitors win on depth of content rather than accumulated references, the gap is a content gap and links will not close it.
- The available budget only reaches the cheap tier: a budget too small to fund research and outreach buys bulk placements instead, which is the tier the policy above describes. Deferring is a better decision than buying the risky version.
The diagnostic is whether the site already ranks for anything. A site with existing positions that plateau against established competitors has an authority problem. A site with no positions and no technical faults has a coverage problem first.
Frequently asked questions
Is buying backlinks against Google’s rules?
Buying links that pass ranking credit is named in Google’s spam policies as a link scheme. The policy also states the compliant alternative. Paid placements are not a violation when qualified with a rel=”nofollow” or rel=”sponsored” attribute, which tells search engines not to pass credit. A sponsorship disclosed that way is a media buy like any other, and its value is the referral traffic it sends.
How many backlinks does a business need?
No published figure answers this, and any vendor quoting one is describing its own inventory rather than the market. The requirement is set by the sites already ranking for the target queries, which differ by category and change over time. A number stated in advance of looking at the competing set is not a measurement.
Can a business build links itself?
Parts of it, and often the highest-value parts. Reclaiming existing unlinked mentions, giving expert comment to journalists, and joining real industry bodies can be done in-house. The limit is usually steady outreach time, which is the component most businesses cannot spare and the reason the work is outsourced.
What happens to a site that already bought links?
The first step is establishing what is actually in the profile. Not every purchased link carries the same exposure, and some may have been removed already. That assessment is covered in auditing an existing backlink profile. What follows depends on whether rankings have already been affected.
