Link Building for Startups: 8 Tactics, Real Costs, and How to Size the Spend (2026)

Most startups guess at their link building campaign. The number of links you need is calculable – you can count the referring domains pointing at the pages currently outranking you, take the median score of the top three, and that’s your target.

For example, on a typical KD 20 term, that’s around 23 domains to reach page one and 66 to reach the top three.

In this guide, I cover the 8 tactics that work on a new domain, what they cost, and how to size the link building for startups spend before you commit budget to it.

I’ve spent 13 years building links for SaaS and eCommerce startups. Here’s what works. But first:

Why Can’t Startups Skip Backlinks?

You can see the real effect of links on any SERP. Ahrefs has pulled the top 20 results for 10K non-branded keywords, 200K pages, and found that the higher-ranking pages consistently hold more referring domains than the ones below them.

This pattern holds across almost every commercial query: the distance between position 8 and position 2, for instance, is more often a link gap than a content gap.

The second reason is this: language models cite sources, and sources they reach for are actually the ones with visible corroboration elsewhere on the web. For instance, a page nobody links to is a page that rarely gets quoted back to a user asking ChatGPT or Perplexity for a recommendation. Links in this case now buy visibility in two systems. If you want the fuller case, we’ve broken down the benefits of link building beyond rankings alone.

8 Link Building Tactics That Actually Work For Startups

Each link building tactic below gets the same breakdown so you can genuinely compare them directly and execute whichever fits your industry and context.

1. Founder-led Digital PR

What it is: As the name describes, your founder answers journalists’ queries from websites like Qwoted, Featured, Help a B2B Writer, plus any direct pitches to reporters who cover your space. The links come as an attribution to the story you didn’t write.

Why it works on a new domain: The reality is, nothing else can get you DR70+ links fast, and this early enough. Publishers won’t link to a company with no traction at all, but they will quote a named human or subject matter expert with a credential and specific inputs. This is the most reliable route we’ve found for how to get backlinks from high authority sites when your domain is brand new. So you’re actually borrowing the founder’s authority here, given that your domain has none of this credibility and trust yet.

What actually gets picked up: Contrarian takes with data numbers attached; examples would be: “we cut our sales team from 6 to 2 and revenue went up 14%” – actual data stories that get quoted.

When to skip this link building tactic: If your founder can’t commit to hours personally, delegating the entire link building work to a marketer writing in the founder’s voice might produce generic quotes, unless they have a context of the industry and the organization.

2. Original Data and Research

What it is: There may be internal case studies you can collect within your organization, like a survey of your users, an analysis of your own product data, a benchmark study of your industry. Then, other publishers will cite it, and citations like this are links you acquire passively.

Why it works on a new domain: Instead of manually reaching out for other content creators to link to your site, you become the available source for others citing your work. It’s the clearest example of creative link building – the asset does the prospecting for you.

What to actually publish: Any valuable data you can publicly publish on your site. For instance, a payments startup knows average invoice-to-payment time by industry. Another would be an HR tool that knows time-to-fill by role. You simply have to look at your own database and find a number that journalists would want to cite.

When to skip it: Pre-launch with no users and no proprietary data. And when commissioning a survey before you have a product, you’re just spending your scarcest resource on your slowest-returning channel.

3. Free Tools and Calculators

This is one of the highest ROI per asset, especially for SaaS. You can build a small thing that’s adjacent to your product that you think people would bookmark and other journalists or bloggers would reference from their own sites.

4. Product Hunt and Launch Platforms

It’s a one-time, high-volume, low-difficulty link-building work. You can get listed in Product Hunt, BetaList, Hacker News, Indie Hackers, and other niche startup directories.

5. Integration, Partner and Customer Pages

This is one of the most underrated startup link sources – as every tool you integrate with, every vendor you pay, every customer with case studies – most of them have partner directories or customer pages, and most will actually link back if asked.

So nearly 100% success rate for this type of link building campaign given that the relationship already exists somewhere. Adjacent to this is testimonial link building – writing a review for a tool you already pay for, in exchange for a link on their site.

6. Podcast Appearances

These are show notes links, low competition and founder-friendly, as you can simply cover how to find shows at your stage – the pitch mostly gets booked (as my podcast hosts want esteemed guests for their show), and the fact that most hosts link to the guest’s company by default.

7. Unlinked Mention Reclamation

The fastest (low-hanging fruit) wins once you have any press at all. You’ll cover brand monitoring setup, reclamation emails, and how typical conversion rates are much higher than other link building strategies for startups. Getting brand mentions for SEO converted into actual links is what link reclamation is built on.

8. Strategic Guest Posting

Listed last deliberately. Here, you cover relevance criteria over just volume of links – which means that having a genuinely good relevant DR40 website can outrank 10 other general marketing blogs – and it’s what really contributes to the better and higher link juice for your startup site. If you’re weighing formats, our comparison of guest posting vs niche edits covers which one suits a new domain, and niche relevant backlinks explains why relevance beats raw DR here.

Which Link Building Tactics To Run At Which Stage?

What changes by stage isn’t really which link building strategies are good, but which ones are actually available with your given resources. You can’t publish product data before you have a product – and this sequence below matches tactics to what you already have.

Pre-launch

At this stage, you run through the founder: answering journalist queries, appearing on podcasts as a guest, building in public, and showing up in communities where your potential buyers already are. None of these would require a product to exist.

You can have a free profile sweep with Crunchbase, LinkedIn, GitHub, and other relevant startup directories. These are the closest thing to easy backlinks a pre-launch startup has access to, and social backlinks from your founder’s own profiles belong in the same sweep. Doing this pre-launch can mean those profiles are already indexed when your launch coverage points at them.

Be careful: Buying links to a landing page with no product behind it. So you’re just paying to accelerate a domain that has nothing to convert on, and anchor profiles you can build now are the ones you’ll use later.

Launch to 6 Months

Product Hunt is one of the obvious tactical things to do here – as it will cover the full spread, instead of just getting listed in BetaList, Hacker News, Indie Hackers, and the niche directories in your category, which may also convert better given that there are fewer of them and their audiences are narrower.

Then, you can do a relationships sweep. Every tool you integrate with, every vendor you pay, every early customer who agreed to logo placement – most of them have a partner directory or customers page – so this will be the highest-conversion link work that’s available to any startup.

Be careful: Spreading your first links across every page on the site. 4 to 6 links must be pointing to the page that moves the revenue. So you have to pick the page carefully.

6 to 18 Months

This is where compounding tactics become available, given that you finally have inputs for them.

You now have usage data, so you can publish original research. Having press mentions from launch, unlinked link reclamation has something to reclaim here. You now have integrations, so tool-adjacent content will have a hook.

This is also the stage where you should run link gap analysis and know exactly your actual targets. It’s also when a B2B link building program starts making sense, or if you’re a software company, a dedicated SaaS backlinks strategy built around your product data.

Be careful: Continue to build homepage links long after the homepage stopped being the bottleneck. So by month 6, the constraint is usually page-level links to 2 to 3 specific commercial pages.

Post-funding

The funding announcement (if you’re getting investors) is one of the largest single link events most startups ever get, and that window is roughly around 72 hours.

What decides whether you can capture it correctly is having the announcement page live and linkable before the news breaks – giving journalists a real asset that’s worth linking to rather than just a boilerplate press release – and having someone assigned to reclaim all the mentions that publish without attributed links – which will be most of them.

Most startups announce, get 30 mentions, and just end up with 8 links – that gap alone is what you should work on with follow-up work.

Be careful: Scaling link building spend to match the new budget before any gap analysis says this is how much you need. Post-funding is when startups simply just buy 100 links a month, and it won’t move the needle on your bottom line. If you do go the paid route, the best places to buy backlinks are the ones that keep placements live long after the invoice clears.

How Many Links Do You Actually Need?

Tactics tell you how to get a link. They don’t tell you how many you need, and that’s the question that decides whether any of this actually works.

Ask an agency and you’ll get a package: 25 links a month, 50, 75. But that number isn’t a matter of opinion – it’s sitting on the SERP you’re trying to rank on, and it takes about 20 minutes to read.

Here’s the method, run end to end on a real keyword: a tax software client targeting “ai tax assistant.” The client is anonymized, but the keyword, the competitors, and every metric are public SERP data you can pull yourself.

Step 1: Read the Keyword, Not the Search Volume

Five numbers come off the Keywords Explorer screen, and each one does a different job:

• Keyword Difficulty 21 – roughly 23 referring domains for the top 10. This is your entry price for page one.
• Search volume 200/month – the least interesting number here, and I’d say that in a client meeting.
• Traffic potential 600 – three times the keyword’s own volume, because one page ranks for many keywords. You’re buying the page’s total, not the keyword’s.
• Traffic value $4,400/month at a $6.00 CPC – what those visits would cost to buy on paid search. This is the figure the whole investment gets measured against.
• Parent topic “ai taxes” at 400 searches – the wider cluster the same page expands into once it ranks.

Difficulty gives you the price of page one. It says nothing about the price of the top three – for that, you have to open the SERP itself.

Step 2: Read the SERP, Page by Page

For every result in the top 10, record page type, word count, DR, URL Rating, backlinks, referring domains, and traffic. Page type is the column people skip, and it’s the one that changes everything.

Step 3: Take the Median, Never the Average

Position 2 ranks with its homepage. Those 1,006 referring domains are every link that company has earned since it existed – its funding coverage, its integrations, its footer links. They are not the cost of ranking that page for this keyword, and nobody built 1,006 domains to win this term. This is also why homepage backlinks have to be read differently from page-level ones.

Average them in and you get a target of 379 domains that nothing on this SERP actually needed. Present that number to a founder and you’ve killed the campaign in the meeting.

The median of 66 is trustworthy because it’s corroborated – two independent pages, on completely different domains, with a 10-point DR spread between them, both landed on exactly 66.

Step 4: Set Two Checkpoints, Not One Target

A single 66-domain target is a 6-month wall with nothing to see for the first quarter. Two checkpoints turn it into something reviewable:

• Top 10 checkpoint – around 23 domains. At roughly 12 page-level links a month, this arrives inside month 2.
• Top 3 target – 66 domains. At the same rate, inside month 6.

Rankings lag link acquisition, so expect first visible movement around month 3 and a fair read at month 6. We’ve mapped the full curve in how long for backlinks to take effect if you need to set expectations internally.

Use the first checkpoint as your kill criteria: if you’re at target link volume by month 3 and the page hasn’t moved at all, something upstream is wrong.

Step 5: Find Who’s Beatable Right Now

The median tells you the price of the top three, but not where the soft spot is. Two results on this same SERP show the range:

• Position 4 – DR 12, with 309 referring domains to the page. A weak domain ranking above much stronger ones because the page itself is heavily linked.
• Position 6 – DR 78, with a single referring domain to the page. A strong domain coasting entirely on sitewide authority.

The DR 78 result is the beatable one, as there’s nothing at the page level to overcome. Sort your top 10 by URL Rating rather than DR – results with high DR and low UR are ranking on domain strength, and those are your first targets. The same export tells you where their links came from, which is a live opportunity to steal your competitors backlinks.

What Link Building Actually Costs

Once you know the gap, you can convert it into dollars. Rates vary by acquisition channel – how much do backlinks cost breaks down what each one runs. At a mid-market rate of around $220 per manually earned DR35+ link, the same keyword prices out like this:

Substitute your own per-link rate if you’re quoted differently – the arithmetic holds either way.

Getting Your Founder To Sign Off

Let’s start first with the reasons why founders push back on link acquisition.

Why Founders Push Back on Link Building

You start by conceding that they’re right to.

• There’s no visible output. For instance, a month of link building can simply just produce a spreadsheet of URLs on other sites’ pages – it feels like just paying for nothing.
• Attribution is genuinely bad. You can’t simply draw a line from a link on a DR50 blog to a signup – so having paid search work that a founder sees, where there’s a dashboard with cost per acquisition on it, is much more appealing for him.
• It’s slow, and in a specific way founders hate. Not really slow like a product build with visible milestones – but the first movement around month 3, you need to see visible signs of results.
• SEO industry earned its reputation. PBNs, Fiverr packages, penalties, agencies that just simply hide their process. So if your founder has been burned before, or read about someone who was, the skepticism isn’t irrational – they simply have pattern recognition. It’s the strongest argument for vetting who you outsource backlinks to in the first place.
• It competes with a channel that reports daily. Mostly, the real objection, given that Ads spend $10K and it will show you what that $10K bought, is that now you’re asking for the same money against a number you won’t actually have yet until month 6, let’s say.

Translate Links Into the Language the Founder Already Uses

The point here is: don’t just present ranking positions – founders want to see traffic, cost, and payback from investments.

These 3 numbers will do the work.

1. Traffic value – what you’d pay to rent the same traffic

Let’s say the page you’re targeting earns 600 visits a month. Those visits may cost you $6.00 each on paid search.

This is what you need to present to your founder.

2. Payback period – when the spend is recouped

You actually know the gap from the link gap analysis: 66 referring domains, from a starting point of zero.

$14,520 to close the gap, against $4,400 a month in equivalent traffic value. It pays for itself a little past month 3 and keeps returning after that.

3. Rent vs. own – what happens when you stop

Consider this.

Paid search is just renting. $3,600 a month can buy 600 visits, every month, forever. You may miss a payment, and the traffic will stop that afternoon. Your cost at month 24 is $86,400, and your asset at month 24 produces nothing.

Links are ownership, essentially. $14,520 once buys a page that keeps earning. At month 24, you’ve spent the same $14,520, and the traffic is still arriving.

That last row is the one to say out loud. The keyword’s own search volume is 200 a month, but the page’s traffic potential is 600 – three times higher, because a page that ranks for one term ranks for dozens of related ones. Paid search buys exactly the keyword you bid on and nothing else.

Be honest about the two rows where paid wins: it’s faster and its attribution is clean. Conceding those is what makes the other rows credible.

State the Caveats Before You’re Asked

Traffic value is a proxy for what the traffic would cost to buy – it is not a revenue forecast. And rankings lag link acquisition, so expect the first movement around month 3 and a fair read at month 6.

Say this in the pitch, not after your founder finds out. Credibility on the downside is what buys you month 4.

De-risk the Ask

• Start with one page and one keyword, not a sitewide program.
• Pick the quick-win keyword from your gap analysis so the first checkpoint arrives inside a quarter.
• Agree the review date, the metric, and the kill criteria before you start.
• Report net link growth, not gross – your link building reporting should show what survived, not just what was acquired.

Bottom Line: Size the Spend Before You Spend It

Most link building for startups fails not because the tactics were wrong, but because nobody ever calculated how many links the target page actually needed. The tactics above will get you links. The gap analysis tells you when to stop – and the payback math is what gets the budget approved in the first place.

Run the analysis before you buy anything. Some keywords come back at 200 domains, and the honest recommendation there is to pick a different keyword.

And once links start landing, keep them – use a backlink monitor tool so you’re reporting net growth rather than gross, and follow the link building best practices that stop a new profile from looking engineered.
