Some links here are affiliate links — if you buy through them we may earn a commission at no extra cost to you. It never changes what we recommend. Full disclosure.
Links from other websites remain one of the strongest signals search engines use to judge which pages deserve to rank. They are also where small sites most often go wrong — either ignoring links entirely or buying cheap ones that do more harm than good.
You do not need a PR agency or a link-buying budget. You need something worth linking to, a short list of the right people, and a polite, persistent outreach habit. This guide covers how links work, safe tactics that suit small budgets, outreach templates that get replies, how to research competitors' links, and how to audit and clean up your own profile.
DIY Link Building for Beginners
What a Good Link Looks Like
- Relevant: from a site in your topic or serving your audience
- Editorial: given because the content is useful, not paid for or swapped
- In context: within the body of a real article, not a footer or a list of hundreds of links
- From a real site: with real readers, traffic and its own reputation
One link from a respected industry publication or a local newspaper is worth more than hundreds of directory or comment links.
Where to Start
- Links you are already owed: suppliers, partners, clients, associations, sponsors, event organisers — anyone who would naturally link to you.
- Unlinked mentions: search your brand name; ask sites that mention you without a link to add one.
- Linkable assets: create something genuinely useful — original data, a free tool, a definitive guide, a template.
- Outreach: introduce that asset to people who write about the topic.
Avoiding DIY Link Building Mistakes That Get You Penalized
Search engines' spam policies prohibit link schemes. Avoid:
- Buying links that pass ranking value (paid placements must use
rel="sponsored"ornofollow) - Link exchanges at scale ("link to me and I'll link to you")
- Private blog networks and sites built only to link out
- Automated links from comment, forum-profile or directory spam
- Guest posts stuffed with keyword-rich links on low-quality sites
- Exact-match anchor text everywhere — natural links mostly use brand names, URLs and descriptive phrases
The risk is not just wasted money: manipulative links can be ignored by algorithms or lead to manual actions that suppress the whole site.
The same applies to other "black hat" tactics that still circulate: cloaking (showing search engines different content from users), hidden text and links, doorway pages (many near-identical pages built to rank for variations and funnel visitors elsewhere), and scraped or auto-generated content. All are named in search engines' spam policies and are detected far more reliably than they once were. White-hat SEO is slower, but it builds an asset; black-hat SEO builds a liability that can disappear overnight.
Safe, Low-Budget Tactics
DIY Broken Link Building
Pages on other sites often link to resources that no longer exist. The tactic:
- Find relevant resource pages and articles in your niche.
- Check their outbound links for broken ones (browser extensions and free crawlers do this).
- If you have — or create — a page that replaces the dead resource, email the site owner: tell them about the broken link and suggest your page as a replacement.
You are doing them a favour first, which makes this one of the friendliest outreach approaches. Tools like the Wayback Machine show what the dead page contained, so your replacement can genuinely fill the gap.
DIY Resource Page Link Building
Many organisations maintain resource pages — "useful links for small businesses", "gardening resources", "tools for teachers". Find them with searches like [topic] "useful resources", [topic] inurl:resources or [topic] "helpful links". If your page genuinely belongs on the list, send a short note explaining what it is and why their readers would find it useful.
DIY Guest Posting Outreach
Guest posting works when it is about reaching a real audience, not about the link. Target respected sites your customers actually read, pitch specific topic ideas tailored to their readers, write your best work, and accept a natural author-bio link. Avoid sites that openly sell "guest posts" with no editorial standards — those are link schemes in disguise.
DIY Digital PR on a Small Budget
Digital PR earns coverage and links by giving journalists something newsworthy:
- Original data: survey your customers, analyse your own anonymised data, or compile public data into a new insight.
- Expert commentary: respond to journalist requests through expert-source services and platforms where reporters look for quotes.
- Local angles: local news sites cover local businesses, events, milestones and community involvement.
- Timely reactions: offer informed commentary on news in your industry quickly.
Keep a simple press page with your story, photos and contact details so journalists can link to and cite you easily.
The Skyscraper Technique and Content-Driven Link Earning
The skyscraper technique — find a popular piece of content with many links, create something substantially better, then ask the sites linking to the original to consider yours — still works, with caveats. "Better" has to mean genuinely more useful (newer data, deeper coverage, better design, original research), not just longer, and outreach must be personal and selective. Everyone has received the generic "I wrote a better version" email; most are ignored.
The broader principle replaced old article marketing, where the same article was syndicated across directories for links. Today, links are earned by publishing something others want to reference — original data, tools, definitive resources, expert commentary — and then making sure the right people know it exists.
Outreach That Gets Replies
DIY Link Building Outreach Email Templates
Keep emails short, personal and focused on the recipient. Three templates to adapt:
Broken link
Subject: Broken link on your [topic] page
Hi [Name], I was reading your [page title] and noticed the link to [resource] now returns an error. I recently published [your page], which covers [what it covers] — it might work as a replacement. Either way, thought you'd want to know about the broken link. Thanks, [Your name]
Resource page
Subject: A resource for your [topic] list
Hi [Name], your [page title] has been really useful to me. I put together [your resource], which [specific benefit] — I think your readers might find it helpful too. Happy to answer any questions. [Your name]
Data / PR pitch
Subject: New data: [one-line finding]
Hi [Name], you've covered [related topic] before, so I thought this might interest you: we found [specific finding] after [method]. Full data and charts here: [link]. Happy to share more detail or comment. [Your name]
Rules that improve reply rates: use the person's name, reference something specific about their site, make one clear ask, follow up once after a week, and never send identical mass emails.
Researching Links
DIY Competitor Backlink Research
Free tiers of backlink tools show a sample of links pointing to a competitor. Look for patterns:
- Which pages attract the most links? (Those are content formats that work in your niche.)
- Which sites link to several competitors but not you? (Warm prospects.)
- Which associations, directories, publications and events link to businesses like yours?
Then earn similar links through better content and outreach — not by copying low-quality ones.
DIY Backlink Audit and Cleanup
Review the links in Search Console's Links report and a backlink tool every few months:
- Most links will be fine — random low-quality links are normal and search engines generally ignore them.
- Watch for patterns that suggest a past link scheme: lots of exact-match commercial anchors, links from obvious link networks, or paid links without
nofollow/sponsored. - Clean up what you control: ask for removal of paid or scheme links you or a previous agency built.
- Disavow only when necessary — Google's disavow tool is for cases with manual actions or a clear history of manipulative links. Most small sites never need it.
Measuring Progress
Track referring domains over time (not raw link counts), the quality and relevance of new linking sites, referral traffic from links, and rankings for the pages you promoted. A handful of relevant, editorial links a month is a strong result for a small site.
The Bottom Line
Sustainable link building is relationship building: claim the links you are already owed, create something genuinely useful, offer help first with broken links and resource suggestions, pitch real stories to journalists, and keep your outreach personal. Skip anything that involves buying, swapping or automating links — the shortcuts cost more than they save.
