Link building is dead. No, the 2019 version of it is dead. Guest post farms, PBNs, and exact-match anchor text at scale stopped working; the discipline underneath — earning references from sites your audience already trusts — is worth more than it has ever been, which is exactly why agencies now charge $350–700 for a single media-request link. The link building strategies below are the ones that still work when you are building 5 to 20 links a month, not 200: media requests, one data study a quarter, a downloadable asset, competitor-gap and broken-link outreach, one guest post a month, and reclaiming the links you already earned.

That scale point matters more than any individual tactic. Almost every link building guide is written from inside an agency that ships hundreds of links a month for enterprise clients, and the advice quietly assumes their headcount. We build links for clients at exactly the 5–20 range, and the playbook at that scale is different: fewer channels, run consistently, with content worth linking to underneath. Here is each strategy, what it costs, and how long it takes.

What makes a link worth building

Four things decide what a backlink is worth: relevance (a marketing site linking to a marketing site), authority (the linking site has real traffic and its own earned links), placement (in the body of an article, not a footer), and anchor text that describes the destination. One editorial link that clears all four bars beats a hundred directory listings — and the hundred directory listings can hurt, because Google's spam policies treat links intended to manipulate rankings as spam regardless of who built them.

One nuance worth knowing before you dismiss nofollow links: since Google's 2019 change, nofollow is a hint rather than a directive, and mentions on high-traffic pages get read by the AI systems deciding which brands to cite. A nofollow mention in a major publication is not a wasted pitch.

Strategy 1 — media requests: the fastest first link

Journalists need expert quotes on deadline. Answer their requests well and you earn editorial links from publications you could never cold-pitch.

The platform landscape changed and most guides have not caught up. HARO — the platform every older article recommends — was renamed Connectively and then shut down in December 2024, before being revived under Featured.com. Today the working platforms are Featured, Qwoted, and Source of Sources, plus the #journorequest hashtag if you can stand the noise.

The mechanics: monitor requests in your niche daily, respond within the hour where you can, lead with the most useful sentence of the answer rather than your credentials, and keep the whole reply short enough to paste straight into an article. Speed is most of the game — journalists file on deadline and take the first three usable quotes, not the best ten.

Budget 30 minutes a day. Expect 1–4 links a month once your response quality settles, at a cost of $0 plus the time. For calibration: agencies charge $350–700 per link for exactly this work, and when Semrush analysed ten of them, the average lowest quote was just over $300 per link. Doing it in-house is the single best labour-for-links trade at small scale.

Strategy 2 — competitor-gap and broken-link outreach

Sites that link to your competitors have already demonstrated they link out to sites like yours. That makes them the warmest cold prospects available.

The process is one afternoon a month. Pull the backlink profiles of two or three competitors, filter for domains that link to more than one of them, and shortlist the pages where a link to your content would improve the article. Then send a short, specific pitch naming the exact section and the exact gap your page fills. No template blast — ten researched emails outperform a hundred sprayed ones.

Broken-link outreach is the same motion with a better hook: find pages in your niche linking to dead URLs, and offer your live page as the replacement. You are opening with a favour — flagging a broken link they want to fix — rather than a request.

Tooling is where this gets affordable. LinkMiner inside Mangools covers backlink prospecting at $29.90 a month on annual billing, and flags dead links in competitor profiles as a built-in filter — our Mangools review covers the whole suite. SEMrush's Backlink Gap tool does the multi-competitor comparison in one report if you are already paying for the platform; the arithmetic on that subscription is in our SEMrush review.

Expect 2–6 links a month from a consistent hour a week, after a slow first month while your prospect list fills.

Strategy 3 — one data study a quarter

Original data is the only content category where strangers link to you without being asked. Writers citing "the average cost of X" need a source; be the source.

The study does not need to be big. Analyse your own client data, run a 200-term test across five tools, survey 100 practitioners — small, specific, and first-hand beats large and generic. Publish the finding with a clear headline number, put the method in the open, and pitch it to the ten publications whose writers cover your beat.

Specificity is what earns the links. One creator spent seven hours building a carousel of actual screenshots of SEO and AI tools — real interfaces, real results, nothing staged. It reached 2 million impressions and 500-plus comments, and people were still finding it months later. Nobody links to "10 tips for better content". They link to the thing that shows its work.

One study a quarter is the right cadence at this scale. Each one keeps earning links for a year or more as new articles on the topic cite it, which is the closest thing link building has to compound interest.

Strategy 4 — a downloadable asset worth pointing at

Templates, checklists, and calculators earn links from resource pages and "further reading" sections long after publication. The asset has to solve one specific job — a content brief template, a link-prospect scoring sheet, an audit checklist — and it has to be genuinely usable, not a lead-gen brochure with a form in front of it.

Build one, then pitch it to resource pages that already list things like it. This is slow-drip rather than campaign: expect 1–2 links a month, indefinitely, for an asset that took a day to make.

Strategy 5 — one guest post a month

Guest posting survived its own death the same way link building did: the farms died, the real version works. One well-placed post a month on a publication with real editorial standards and an audience that overlaps yours — pitched with a specific angle, written properly — earns a contextual link and puts your name in front of readers who hire and buy.

Point the link at a hub page or a genuinely useful resource, not a money page; editors notice, and the hub passes authority onward anyway. Check the publication's link policy before writing a word — some allow one bio link only, some mark everything nofollow. Write it anyway if the audience is right. One a month is the ceiling worth respecting: each good post costs a working day, and at 5–20 links a month the outreach channels above are a better use of the next day.

Strategy 6 — reclaim what you already earned

Two free links a month are usually sitting in your existing footprint. Unlinked mentions — someone named your brand without linking — convert with a two-line thank-you email. Lost links — pages that used to link to you and stopped — come back with a polite note, especially if you have updated the target page since.

Check for both monthly. It is the lowest-effort item on this list and the warmest outreach you will ever send, because the recipient has already decided you are worth referencing once.

The maths at 5–20 links a month

What the loop looks like as a monthly operating rhythm, from running it for clients:

Total: roughly 30 hours and $30 a month for 6–18 links. That time figure is the honest cost most guides bury — this is a part-time job, done properly. The agency alternative runs $300–700 per equivalent link, which is why the in-house loop wins at small scale and why agencies win the moment your time is worth more than the difference.

What to skip

Paid link networks, PBNs, bulk directory submissions, and comment links. Not because they never move rankings — because they are the exact patterns Google's link spam systems are trained on, and a manual action costs more months than the links ever bought. Fiverr packages selling "50 DA50+ backlinks" are selling all four of the above in a trench coat.

Skip mass cold outreach too, on economics rather than ethics: sub-1% reply rates mean you need volume tooling and list-buying to make it pay, and at that point you are running the agency model without the agency's economies of scale.

The pitch email, since every strategy above ends in one

Four of the six strategies end with you emailing a stranger, so the email is worth getting right once. The pattern that gets replies for us:

- A subject line that names their page, not your content. "Broken link on your keyword research guide" gets opened; "Content partnership opportunity" gets deleted. - One specific observation in the first sentence that proves a human read the page — the section, the paragraph, the dead URL. - The ask, stated plainly, in sentence two or three. What page, what anchor context, why the reader benefits. Editors know what link outreach is; pretending otherwise wastes their time and yours. - Nothing else. No paragraph about your company, no "I hope this finds you well", no follow-up sequence beyond one polite nudge a week later.

Five sentences, sent to someone whose page genuinely improves with the link. Every reply-rate problem we have ever diagnosed traced back to violating one of those four points — usually the first sentence, because researching the page is the part that does not scale, and the part that works precisely because it does not.

When not to build links

If your site has fewer than about 20 pages of substantive content, stop. Outreach cannot fix an asset problem — every strategy above depends on having something a stranger would voluntarily reference, and prospects check. Publish first, build links second.

The same applies if rankings are drifting while nothing new has shipped: links amplify content velocity, they do not replace it. And if search is not a primary channel for your business yet, 30 hours a month is better spent on whatever channel is.

If the content exists and the 30 hours do not, that is the one version of this problem money solves cleanly — it is also the job our content writing and link building service does for clients, running exactly the loop in this post and reporting the referring domains to prove it.

The loop, in order

Start with reclamation and media requests in week one — they need no new content and produce the first links fastest. Add competitor-gap outreach in month one, the downloadable asset in month two, the first data study in the first quarter, and guest posts when the rest is humming. Rankings follow referring domains on a lag of two to four months; track it with one of the rank tracking tools we compared rather than refreshing the SERP by hand.
