Does Link Building Still Work? Myths vs Facts

Google has spent the last two years telling everyone that links matter less — and interest in “link building” hit an all-time high on Google Trends anyway, with a sharp uptick starting February 2025.^[1] That gap between the official line and what practitioners actually do is where link building myths live.

Here’s the short version of what the data says:

• Links still correlate with rankings. Ahrefs analyzed 1,000,000 SERPs specifically to test Google’s “links matter less” claim and found referring domains still track with rankings.^[1]
• Volume is not the lever. Google’s #1 result has on average 3.8x more backlinks than positions #2–#10, but that’s accumulated quality, not bulk buying.^[2]
• AI search didn’t kill links. AI answers pull citations from the top 10 results roughly 75% of the time.^[1]
• Bad advice is expensive. 62.67% of SEO professionals spend under $1,000/month on link building.^[2] Burn that on the wrong tactic and you lose runway, not just rankings.

Below are 9 myths sorted into three buckets — myths that waste money, myths that create risk, and myths invented by the AI search panic — each tested against current data and named practitioners, and each judged from a startup’s position: small budget, no in-house SEO team, no engagement history to lean on.

Why Link Building Myths Spread Faster Than Facts

Three mechanics produce almost every myth in this space:

1. Google’s public statements get compressed into headlines. “Links are one of many signals” becomes “links don’t matter.”
2. Tactics abused in 2012 get labeled dead forever. The abuse gets penalized; the label sticks to the whole category.
3. Agencies repeat claims that support what they sell. If you sell $4,000 editorial placements, “cheap links are dangerous” is a convenient truth.

Then there’s the market reality. The global link-building services market is estimated at $25.97 billion in 2025 and projected to reach $57.07 billion by 2030.^[10] Businesses don’t fund a tactic at that scale after it stops working.

The Myth Filter: Three Questions to Test Any Link Building Claim

Before you act on any link building advice, ask:

• Is there a study behind it, or only an opinion?
• What year is the evidence from? Pre- or post-2024 core and spam updates?
• Does it apply to a site with 0–50 referring domains, or only to established brands?

That second question matters more than people think. The March 2026 core update^[8] and the June 2026 spam update — which targets scaled and templated content through SpamBrain^[7] — changed which tactics are safe. Advice written in 2021 was never stress-tested against either.

With that filter in hand, start with the myths that quietly drain budgets.

Link Building Myths That Waste Your Budget

Myth 1: “More links always means better rankings”

The 3.8x backlink gap at position #1 is real^[2] — but it describes what winning pages accumulated over time, not what you can purchase this quarter.

“You could go off and create millions of links across millions of websites if you wanted to, and we could just ignore them all… Or there could be one really good link from one website out there that is, for us, a really important sign.”

— John Mueller, Google Search Advocate^[2]

The startup angle is more encouraging than most founders expect: 94% of published web pages have zero backlinks, and only 2.2% have more than one.^[2] Earning your first quality backlinks and going from 0 to 20 relevant referring domains moves you further than adding link #300 to an already bloated profile.

Myth 2: “Only high-DR links are worth pursuing”

DR is a proxy. Relevance is the signal.

“Relevancy isn’t king? No, no, no. Relevancy is absolutely king.”

— Shannon McGuirk, Director at Aira^[4]

There’s a measurable version of this. In local queries such as “best steaks in San Diego,” backlinks and referring domains correlate more strongly with rankings than in non-local queries — because Google leans harder on links when click data is thin.^[1] A startup three months post-launch is in exactly that low-data position.

Practically: mid-DR niche and local sites often send more qualified referral traffic than irrelevant high-DA placements, and a pile of unrelated authority links can start to look manipulative.^[5] If you’re fixing weak Domain Rating and poor keyword rankings, topical fit does more work than a big number in your SEO tool.

Myth 3: “Guest posting is the cheap, easy way to get links”

Look at the price spread. 98% of guest posting sites are low quality — DR under 40 and under 10K monthly organic traffic — while a genuinely high-quality or top-tier guest post costs $3,130–$6,018.^[1] The average paid guest post sits at $77.80.^[2] That arithmetic tells you exactly which tier most “cheap guest posts” come from.

Then add the hidden cost: SEOs typically spend 1–2 hours to build a single link.^[2] A founder doing outreach personally is paying with the scarcest resource in the company.

Guest posting isn’t dead. It just requires screening on real organic traffic, referring domains, and editorial standards — not DA alone.^[5]

Wasted money hurts. The next group of myths does something worse: it stops people from building links at all.

Link Building Myths That Create Risk (or Just Paralysis)

Myth 4: “A few low-quality or low-DR links will get you penalized”

There’s a difference between ignored links and penalized patterns. The June 2026 spam update targets scaled and templated content and manipulative patterns through SpamBrain^[7] — not the occasional low-authority citation that every real website on the internet accumulates.

What actually raises risk: mass-purchased links, templated placements repeated across hundreds of sites, and site-wide footer links. “Spam score” panic articles routinely conflate those tactics with normal, messy, organic link profiles.^[12] If you can buy it in bulk with one checkbox, that’s the pattern spam systems are looking for.

Myth 5: “Nofollow links are worthless” and “reciprocal links are always bad”

Natural link profiles contain a mix of followed and nofollowed links — and dofollow-only profiles show up more often on spammy sites.^[6] A profile that is 100% dofollow looks engineered, because it is.

“Top-tier news sites only give you nofollow links. Well, let me tell you this is completely false. We have had numerous links from top-tier sites from a variety of different writers.”

— Shannon McGuirk, Director at Aira^[4]

On reciprocity: 73.6% of domains have reciprocal links, meaning some sites they link to also link back.^[3] Mutual linking is a normal property of the web when it reflects real relationships.

One nuance most articles skip: links on the same page don’t pass equal value. Google’s patent “Ranking documents based on user behavior and/or feature data” lists link position in the HTML, font size, position in a list, and surrounding context as factors.^[6] A link inside relevant body copy is not the same asset as the 40th item in a footer list.

Myth 6: “You can’t ask for a link”

“You can’t ask for a link. Again, completely false. You absolutely can ask for a link.”

— Shannon McGuirk, Director at Aira^[4]

The condition is that you’ve given the publisher a genuine reason first. McGuirk’s worked example: a company earned links to product and category pages — not just the homepage — by hosting an exclusive journalist discount code on those pages, which gave the publication a concrete reason to link deeper.^[4]

The newest myths, though, didn’t come from 2012. They came from AI.

AI Search Myths: What Changes and What Doesn’t

Myth 7: “AI Overviews and ChatGPT made backlinks obsolete”

The citation mechanics say otherwise. AI still pulls its citations from the top 10 search results roughly 75% of the time, so ranking well remains the entry ticket to being cited at all.^[1] And 65% of users still click traditional blue links rather than AI-generated answers.^[1]

Practitioners agree: 94% of marketers believe links will still impact Google rankings in five years, and 59% of SEO experts expect backlinks to have a larger impact in coming years.^[2] Google itself frames the shift as combining search capabilities with AI, not replacing the ranking system underneath.^[9]

What Actually Changed: Brand Mentions Now Sit Alongside Links

Here’s the nuance most “links are dead” takes miss. Referring domains and backlinks correlate only lightly with appearing in AI Overviews — branded web mentions, often unlinked, correlate more strongly.^[1]

The industry is already adjusting: 76.4% of digital PR professionals have changed strategy because of AI, roughly 20% still aren’t tracking AI citations at all, and 48.6% of SEO professionals now name digital PR the most effective link building tactic.^[1]

The startup implication: a placement that produces both a link and a named brand mention on a topically relevant page is now worth more than a link-only placement. Which brings us to the tactic that does exactly that — and that everyone insists is dead.

“Directory Submissions Are Dead”: The Link Building Myth That Costs Startups Their Easiest Wins

Two very different things share one name.

Era one: 2000s automated blasts to thousands of generic link farms — templated, unmoderated, zero human review. That’s precisely the pattern SpamBrain-driven updates target.^[7]

Era two: manually built listings on curated, moderated, topically relevant startup directories. Different mechanism, different outcome. Industry directories, business organizations, and local sponsorships are explicitly recommended as legitimate profile-diversification sources, and secondary relevance — audience overlap without direct competition — carries real value.^[5]

Recall that links matter more where Google lacks click and engagement data.^[1] A three-month-old product with no brand searches is the definition of a low-data entity. Directory listings also produce the link-plus-brand-mention combination that now correlates with AI visibility.

Use this quality screen before submitting anywhere:

• Is the directory moderated by humans, or does it auto-approve?
• Does it have real organic traffic?
• Are listings categorized by topic?
• Does it actually send referral clicks?
• Are its listing pages indexed in Google, or invisible to search?
• Is each listing unique, or a template with your name pasted in?

The honest catch is workload. At 1–2 hours per link^[2], researching and manually submitting to 100+ relevant directories is 100–200 founder hours. That’s the gap SR Booster’s startup directory submission service fills: agents analyze your profile, select relevant directories, manually create each listing, and deliver a live report with profile links, logins, and screenshots in about two weeks.

Knowing which myths to ignore is only half the job — the other half is ordering the work.

A Prioritized Link Building Plan for Startups

Myths aren’t equally expensive, so triage them:

Myth	Category	What the Data Says	What to Do Instead
More links = better rankings	Wastes money	#1 has 3.8x more backlinks, but Google can ignore mass-built links[2]	Target your first 20–50 relevant referring domains
Only high-DR links count	Wastes money	Link correlation is strongest in local/low-data queries[1]	Screen for topical relevance and referral clicks[5]
Guest posting is cheap and easy	Wastes money	98% of guest post sites are low quality; top-tier costs $3,130–$6,018[1]	Vet on traffic and editorial standards, or skip the tier entirely
Low-DR links cause penalties	Creates risk (imagined)	Spam systems target scaled, templated patterns[7]	Avoid bulk and footer-wide placements, not small citations
Nofollow and reciprocal links are bad	Creates risk (imagined)	73.6% of domains have reciprocal links[3]; dofollow-only skews spammy[6]	Keep a natural mix; value in-content placement
You can’t ask for a link	Creates risk (imagined)	Practitioners ask successfully with a real hook[4]	Offer something linkable before asking
AI made backlinks obsolete	AI-era confusion	~75% of AI citations come from top-10 results[1]	Keep ranking; add brand-mention coverage
Only links matter for AI visibility	AI-era confusion	Branded mentions correlate more with AI Overviews[1]	Prioritize placements giving link + named mention
Directory submissions are dead	AI-era confusion	Directories are recommended diversification sources[5]	Use moderated, categorized, traffic-bearing directories

Timelines: 49% of marketers say results appear in under 3 months and 30% say under 6 months.^[2] Top-ranking pages gain new followed referring domains at +5% to +14.5% per month.^[3] Sustained velocity beats a one-time blitz.

Vertical difficulty: Healthcare, Accountancy, and Law are the hardest verticals for link building; Leisure/Tourism, Creative arts/design, and Hospitality are the easiest.^[2][5] Set expectations before you set a budget.

Budget math: the average acceptable price for one high-quality backlink is $508.95, against typical total spend under $1,000/month.^[2] That’s two links a month. Foundational assets like directory listings, citations, and profile diversification come first precisely because $3,000+ editorial placements^[1] don’t fit that arithmetic yet.

Key Takeaways

• Links still correlate with rankings across 1,000,000 analyzed SERPs.^[1] No current dataset supports “links are dead.”
• Volume isn’t the lever. The 3.8x gap at #1 reflects accumulated quality, and Mueller confirms Google can simply ignore mass-built links.^[2]
• Relevance beats raw DR, especially in local and low-data queries where link correlation is strongest.^[1][4]
• AI shifts the mix, not the fundamentals. Top-10 rankings feed ~75% of AI citations, while brand mentions become a parallel priority.^[1]
• Curated manual directory listings are not 2000s link farms, and they remain one of the few link sources a startup can build cheaply at scale.
• Plan for monthly velocity (+5% to +14.5% for leading pages^[3]) and realistic vertical difficulty instead of expecting one campaign to close a competitor’s link gap.

If the real blocker is time rather than belief — 100–200 hours of research and manual submissions you don’t have — that’s the specific problem SR Booster was built to remove: 120+ relevant startup directories, handled manually, reported back with proof.

FAQs

Is link building still relevant for SEO in 2026?

Yes. Ahrefs tested Google’s “links matter less” messaging across 1,000,000 SERPs and still found referring domains correlating with rankings.^[1] Practitioner sentiment matches: 94% of marketers expect links to still influence rankings in five years.^[2]

Do directory submissions still work for link building?

Curated, human-moderated, topically relevant directories still work and are recommended as legitimate profile diversification.^[5] What doesn’t work is automated blasting to generic link farms, which is the templated pattern spam systems target.^[7] Screen for moderation, real traffic, topic categories, and unique listings.

Can too many backlinks hurt my rankings?

Quantity alone isn’t the problem — patterns are. Scaled, templated, or footer-wide manipulative placements are what SpamBrain-driven updates address.^[7] Google can also simply ignore links it doesn’t trust rather than punish you for them.^[2]

How much does link building typically cost for a startup?

Most teams spend under $1,000/month, while the average acceptable price for one high-quality backlink is $508.95.^[2] Top-tier guest posts run $3,130–$6,018 each.^[1] For early-stage startups, foundational assets like directory listings and citations deliver more coverage per dollar.

Is asking for backlinks against Google’s guidelines?

Asking isn’t the issue; buying or manipulating is. As Shannon McGuirk of Aira puts it, “You absolutely can ask for a link” — provided you’ve given the publisher a genuine reason first, such as exclusive data or an offer worth referencing.^[4]
