Link Building for Startups: How to Get Your First 100 Backlinks

Most link building guides assume you have an established domain with some authority behind it. For a startup with a brand-new domain and zero existing links, those strategies are frustrating at best and useless at worst. Nobody will accept your guest post if your domain authority is 0. Journalists won't link to a site they've never heard of.

Startups need a different approach — especially for SEO for SaaS startup environments. One that starts where they actually are, builds momentum quickly, and lays the foundation for the authority links that come later. This is the link building strategy that actually works when you need to get backlinks for new website domains.

Why Is Link Building Different for Startups?

Startups face a fundamental chicken-and-egg problem with link building. High-authority editorial links require domain authority. Domain authority comes from links. How do you get the first links when you have no authority to leverage?

The answer is to start with link types that don't require existing authority: directory listings, profile links, and launch platform submissions. These links are given based on your product's existence and quality, not your domain's existing reputation. They build the foundation that makes future, harder links possible.

The Zero-Authority Starting Point

A new domain with zero backlinks ranks for almost nothing organic. Google's crawlers may not even find it for weeks without external links pointing to it. Your first goal isn't ranking: it's indexation, then crawlability, then topical trust. The fastest path through all three is a set of foundational links from trusted domains that already have Google's crawlers visiting them daily.

Why the Standard Advice Doesn't Work for New Sites

Advice like "write great content and links will come" or "do HARO for free backlinks" is true eventually. But both strategies require a foundation of domain trust that new sites don't have. Journalists ignore pitches from unknown domains. HARO responses rarely get featured when competing against established sites. Start with what works now, build authority, then layer in the harder tactics.

The Fastest Legitimate Backlink Sources for New Domains

Here are the backlink sources available on day one of a new startup, organized by how fast you can get them and how much SEO value they deliver.

Week 1: Directory and Profile Links (Days 1-7)

Directory submissions and profile links are the fastest backlinks available to a new domain. Submit to Crunchbase, AngelList, G2, ProductHunt, and your top 5 niche or AI tool directories in your first week. Create professional profiles on GitHub, LinkedIn, and Peerlist. These links go live within hours to days and immediately establish your domain in Google's reference graph.

Our link building service on autopilot handles this entire phase for you, covering 50+ curated directories and profiles in a safe, gradual cadence. See our complete startup directory submission guide for the full list of platforms to target.

Weeks 2-4: Launch Platforms and Review Sites

After your initial directory submissions, launch on Product Hunt, BetaList, and Uneed. These platforms attract the most engaged early-adopter communities and give you dofollow backlinks from high-DA domains. Simultaneously, begin requesting reviews on Capterra and G2. Even 3 to 5 early reviews unlock organic search visibility on these platforms.

Month 2+: Guest Posts and HARO

By month 2, your domain has a handful of links and some crawl history. At this point, you can start pitching guest posts to smaller blogs in your niche. Your acceptance rate will still be modest, but it's better than month one. Begin monitoring HARO (Help a Reporter Out) daily for queries that match your expertise. Responding consistently to relevant queries builds journalist relationships that pay off in editorial backlinks over time.

How to Use Directories as Your Link Building Foundation

Directory submissions are the first 30 to 50 links for virtually every startup. They're safe to build at scale, don't require domain authority to access, and provide both link equity and referral traffic. They're not the finish line: they're the foundation that makes everything else possible.

The Compounding Effect of Foundational Links

Each directory link Google crawls helps it understand your site's topic, legitimacy, and basic authority. Once Google has crawled 10 to 20 links pointing to your domain from trusted sources, it begins assigning topical trust signals that make your content more likely to rank for long-tail queries. This is why the first 30 links matter disproportionately more than links 31 through 60.

Which Directories Give the Strongest Signals

For startups, prioritize Crunchbase, AngelList, Product Hunt, G2, Capterra, and your top 3 to 5 niche directories as your first tier. These are high-DA platforms that Google trusts deeply. Then move to general startup directories and business listing sites. See our full breakdown in the guide to which directory backlinks are good for SEO.

What Link Building Strategies Work Beyond Directories?

Beyond directories, the three most effective link building strategies for startups are HARO/PR outreach, partnership links, and content-driven links from genuinely useful resources. All three require some domain authority to work well, which is why directories come first.

HARO and Journalist Outreach

HARO (Help a Reporter Out), now integrated with Cision, connects journalists seeking expert sources with businesses that can provide them. Subscribe to the daily emails and respond to queries where you have genuine expertise. The acceptance rate is low, but a single placement in a major publication can earn a backlink worth more than 50 directory links. Consistency is key: respond to 5 to 10 relevant queries per week.

Partnership and Integration Links

If your product integrates with other tools or has technology partners, ask those partners to link to your integration documentation or listing on their website. These links are contextually relevant, come from trusted domains in your space, and often require nothing more than an email. Integration partner links are among the easiest high-quality links for SaaS products to earn without paid outreach.

Link-Worthy Content

Create one definitive resource that earns links organically. This could be an original data study, a free tool, a comprehensive guide, or a uniquely useful template. A single piece of genuinely useful content that other sites in your niche reference produces a compounding stream of links for months.

How Fast Should a Startup Build Links?

Link velocity, the rate at which you acquire new backlinks, is as important as the quality of those links. Unnatural spikes trigger scrutiny. Flat, consistent growth signals organic link earning. Here is a safe velocity guide for startup SEO link building.

Months 1-2: Establish the Foundation

Build 10 to 20 new links per month in your first two months. Focus entirely on directories, profiles, and launch platforms. This is the only period where 80%+ of your links can safely come from a single source type, because it mirrors how every legitimate new business starts.

Months 3-6: Diversify and Scale

Increase to 15 to 30 links per month, introducing guest posts, HARO placements, and review site links. Your anchor text diversity should naturally broaden as link sources diversify. Use Boostramp to monitor your anchor text distribution and catch any over-concentration before it becomes a pattern that Google flags.

Month 7 and Beyond: Authority Mode

Scale to 30 to 60 links per month with a full mix of editorial, content-driven, and partnership links supplementing your ongoing directory and review site building. At this point, a significant portion of your new links should be earned organically from content you've published.
