Link Building Mistakes and What to Do Instead
What link building is, which mistakes put a site at risk, what Google's spam policy says about buying links, and how a small business can earn them.

What link building is
Links from other websites still matter for search, which is why bad advice and risky offers are common. This guide covers the mistakes to avoid and the honest ways to earn links.
Link building is the work of getting other websites to link to yours. The common mistakes are buying links to pass ranking power, mass directory and guest post campaigns, link swaps at scale and chasing a link count. Google's spam policies treat buying or selling links for ranking purposes as link spam. Earning links through useful pages and real relationships is slower and safer.
Link building is the practice of getting other websites to link to yours. A link is a clickable reference from one page to another. When a local newspaper, a supplier or a customer's blog links to a page on your site, that is a backlink. Most link building mistakes come from trying to arrange links instead of earning them.
Links matter for two reasons. They send visitors, because people click them. They also help search engines find pages and judge which ones other sites think are worth referencing. Google's guide to its ranking systems says it uses link analysis systems to understand how pages are linked to each other, and that PageRank is still part of its core ranking systems. Links are one input among many, though.
Links also come up in talk of AI answers. The guide to SEO vs AEO vs GEO shows how those terms relate to ordinary SEO. The rule for links stays the same: earn them, do not arrange them.
Link building mistakes that put a site at risk
Buying links to pass ranking power
Paying a site owner for a link in order to improve rankings is the best-known mistake. Google's spam policies treat buying or selling links for ranking purposes as link spam. The next section explains where the line sits.
Mass directory, comment and profile links
Submitting a site to long lists of directories, leaving link comments on unrelated blogs and using software to create links are old tactics that are still sold. Google's policy names automated link creation as link spam. A listing on a real local or trade directory is ordinary business visibility. A listing on a site that no customer has heard of is not.
Link swaps and guest posts at scale
Two businesses that genuinely refer to each other can link to each other. Google's policy lists excessive link exchanges, and partner pages made only for cross-linking, as link spam. Guest articles follow the same logic. Google has said it does not discourage articles that inform another site's readers. It treats them as a link scheme when the main aim is to build links at scale, for example by placing keyword-rich links in articles across many sites, or by using writers who do not know the subject.
Repeating the same keyword as the anchor text
Anchor text is the clickable wording of a link. Natural links vary: a business name, a page title, a plain description. A link profile where nearly every link carries the exact phrase you want to rank for looks arranged. Google's guidance on large-scale article campaigns lists stuffing keyword-rich links into articles as a sign of a link scheme.
Chasing a link count or a tool score
SEO tools show numbers for the links a site has and for its supposed authority. These are the tool makers' own estimates, and different tools give different figures for the same site. A few links from sites your customers read are worth more than a long list from pages nobody visits.
Disavowing links by reflex
Some owners see a list of toxic links in an SEO tool and upload a disavow file. Google describes the disavow tool as an advanced feature, says that in most cases it can assess which links to trust without extra guidance, and warns that incorrect use can harm a site's performance in search. A warning in a third-party tool is not a reason to use it.
Is buying links allowed?
Buying links to improve rankings is against Google's spam policies. The policy describes link spam as creating links to or from a site primarily to manipulate search rankings. It lists buying or selling links for ranking purposes, which includes exchanging money for links or for posts that contain links, exchanging goods or services for links, and sending someone a product in return for writing about it with a link. Pages or whole sites that break the policies can be ranked lower or left out of Google Search.
Advertising is different. Sponsorships, paid listings and advertorials are a normal part of the web. Google's documentation says links of that kind should be marked with rel="sponsored" or rel="nofollow" so that they do not pass ranking credit. Google treats these attributes as hints. The question is therefore not whether money changed hands but whether the link is presented honestly. A marked link can still send you visitors and customers. It cannot be used to push rankings.
In practice:
- Do not pay anyone to place an unmarked link to your site, whether on its own or inside a package.
- If you pay for a sponsorship, advert or advertorial, ask for the link to be marked as sponsored.
- If you send products to reviewers, ask them to mark any link as sponsored, or to leave the link out.
- Paying a person or agency for outreach, writing or promotion is a different purchase from paying a site owner for a link. Ask which one you are buying.
- Policies change, so read the current Google Search Central spam policies yourself before you sign anything.
What counts as a good link
A good link is one that a real person chose to place because your page helped their readers. That is the signal search engines are trying to find, and a few questions will test for it.
| Question | A healthy answer | A warning sign |
|---|---|---|
| Who decided to place the link? | The site owner or writer, because it helps their readers | You, or someone you paid, with no marking |
| Is the site relevant? | Its readers could plausibly use your page or buy from you | It covers unrelated topics or exists to carry links |
| Where does it sit? | Inside useful text or a clear list of resources | In a footer, a sidebar or a block of unrelated links |
| Would it exist without search engines? | Yes, it still helps a reader | No, it only makes sense for ranking |
| Does anyone read the page? | Real readers, even a small number | No readers and no other useful content |
| How is it worded? | A name, a page title or a plain description | The same keyword phrase every time |
One link from a local business group, a supplier or a trade site that your customers read can be worth more than many from pages nobody visits. A link on a page that sends you real enquiries is good for the business whatever it does for rankings.
Why spammy links do harm
Links bought or built for ranking leave patterns that Google's systems are designed to find. Google has said that its spam-prevention system, SpamBrain, can detect both sites that buy links and sites used to pass them. Google has also said that sites which publish or acquire links through excessive sponsored or guest posts without the right link tags may face algorithmic and manual actions.
A penalty is not the only cost:
- The money is wasted if the links are ignored, and you cannot see whether they were.
- Cleaning up later takes effort: finding the links, asking sellers to remove or mark them and, after a manual action, submitting a reconsideration request.
- Links from low-quality or hacked sites connect your name to places your customers would not want to see it.
If an earlier agency or freelancer left you with poor links, there is no need to panic. Google says it can usually assess which links to trust without extra help. Check Search Console for a manual action message first. Cleanup or a disavow file is worth considering only when there is a manual action, or a large pattern of paid or artificial links that you or someone working for you created. Ask an adviser before uploading one.
How a small business can earn links honestly
Honest link building starts with a page worth linking to and ends with telling the right people. It is slow, and nobody can promise a number of links. These routes suit a small business.
Publish something other people can cite
Links go to pages with a reason to be referenced: a clear explanation of a process in your field, local information nobody else has gathered, photographs of your own work, or a plain-language guide to a choice your customers face. Write for the customer, not for linkers.
Ask where you already have a relationship
Suppliers, makers, clients, event organisers, industry bodies and local business groups often keep pages that list members, partners or stockists. If you appear on one without a link, a polite request is reasonable. Searching for your business name will also turn up mentions that do not link to you.
Be listed where customers already look
Genuine local and trade directories, and a complete Google Business Profile, send visitors and help people confirm that you exist. Choose them for the customers they bring, and skip any whose only appeal is a link.
Contribute where your audience reads
An article for a trade publication, a quote for a journalist or a talk at a local event can put your name in front of the right readers. Do it because those readers will benefit, and include one relevant link. If a site asks for payment to publish you, treat that as advertising and expect the link to be marked as sponsored.
Do things worth reporting
Sponsoring a local event, running a workshop or launching something new gives local media and organisers a reason to write about you. The link follows from the coverage. If an organiser marks a paid link as sponsored, that is normal.
Look after the links you already have
The Links report in Search Console shows which pages other sites link to. If a page that earned links was deleted or moved, point it to the closest replacement with a permanent redirect so that visitors and search engines land somewhere useful. The website redesign SEO checklist explains how to do this during a rebuild.
Link building vs digital PR
Link building starts from the link: find a site, get a link. Digital PR starts from a story. You create something worth reporting, offer it to journalists, bloggers and publications, and accept the links that follow. The link is a by-product of the coverage, which is why links earned this way tend to be genuine editorial links.
For a small local business, PR is usually modest: a news item about an opening or an event, a comment in a trade article, a profile on a partner's site. It needs a real story, and no one can promise a placement. If the only reason a link exists is that you wanted it, it is probably the wrong link.
Questions to ask anyone selling link building
- Where will the links appear? Ask for example sites before you agree, not after.
- How are they obtained? Outreach and useful content are reasonable. Networks of sites built to pass links, or software that creates them, are not.
- Will any paid or sponsored link be marked as sponsored?
- Who writes the content, and do they know the subject?
- What will the monthly report show? Work done and links gained are fair. Promises about positions are not.
- What happens to the links if we stop working together?
If you would like a team to review your site before you spend anything on links, the SEO service page explains what Liftup covers. A review often shows that the pages need work before any link would help.
Questions and answers
What is link building?
Link building is the work of getting other websites to link to yours. The honest version means publishing pages worth citing and telling the people who would find them useful. The risky version means buying, swapping or automating links to influence rankings.
Is buying links allowed?
Google's spam policies treat buying or selling links for ranking purposes as link spam. Paid advertising and sponsorship are normal, but the links they produce should be marked with rel="sponsored" or rel="nofollow". Read the current policy on Google Search Central before paying anyone.
What counts as a good link?
A good link is placed by a real person because your page helps their readers, on a relevant site where people read. It sits inside useful text and would still make sense if search engines did not exist.
Why do spammy links do harm?
Google says its systems can detect link buying and sites that pass links, and pages or sites that break its spam policies can be ranked lower or left out of results. Even without a penalty you lose the money, and cleaning up later takes time.
How can a small business earn links honestly?
Publish pages that others have a reason to cite, ask suppliers, partners and local groups to link where they already mention you, and take part in local and trade communities. It is slower than buying links, and nobody can promise a number or a date.
Is link building the same as digital PR?
No. Link building starts from the link you want, while digital PR starts from a story that publications might report. The two overlap, because coverage often brings links, but PR cannot promise a link or a placement.
Do I need the disavow tool?
Usually not. Google describes the tool as an advanced feature and says it can normally assess which links to trust on its own. Consider it only if you have a manual action or a large set of artificial links you caused, and take advice first.
