FusionAuth's /buildvsbuy page mostly answers its LinkedIn ads, but the hero leads with the wrong question
We scored 2 unique copy variants from a 5-ad LinkedIn cluster pointing to fusionauth.io/buildvsbuy. The dominant ad promises 'Identity built for modern teams' with total control over the user auth experience. The page delivers a build-vs-buy decision tool, a TCO calculator, compliance proof, and three customer case studies. The gap is the hero: the H1 asks a decision question instead of echoing the identity-platform promise the ad just made.

The verdict
FusionAuth scores 6.4 out of 10 on message match for fusionauth.io/buildvsbuy. The page's substance lines up with what the LinkedIn ads imply: control over the auth experience, replacement for homegrown systems, SOC 2 and GDPR proof, and a concrete cost comparison. The problem is the hero. Four of five ads lead with 'Identity built for modern teams,' but the page H1 reads 'Should You Build or Buy Authentication?'
That headline asks a question; the ad already answered it. Visitors clicking from a modern-identity promise are dropped onto a decision framework, which adds a translation step before they reach the FusionAuth product story. Offer continuity below the fold rescues the page, but the hero is doing less work than it could.

Identity built for modern teams
We pulled 5 ads from the LinkedIn Ad Library, which collapse into 2 unique copy variants. The dominant variant runs across four ads in the cluster: headline 'Identity built for modern teams,' body 'Total control over your user's auth experience, without having to build it from scratch. Discover FusionAuth here.' The CTA is 'Learn more.' UTM tags show this variant served retargeting audiences for software engineering and CTO segments.
The second variant is a single ad under a 'WTD' (worth the dollars) account-list campaign. Its headline is 'Your auth might seem free (Except for the 3 engineers maintaining it…),' and the body pitches FusionAuth as a complete platform you can download and run on your own infrastructure, ending with 'Discover what you can save each year here.' That variant is the closest match to the page's TCO calculator and savings claim.

What the page promises
The page is a long-form build-vs-buy resource with a calculator at the top. The H1 asks the decision question, and the subhead reads 'Dedicated architecture. Self-hosted or on FusionAuth cloud.' Trust stats anchor the hero: 50M+ downloads, ISO 27001 compliant, 99.99% uptime SLA, data residency control, and SOC 2 certification.
Below the hero the Total Cost of Ownership Calculator lets visitors plug in engineer count, salary, user volume, and timeline, then compares Build In-House, Traditional SaaS, and FusionAuth side by side. A five-question quick assessment delivers a personalized recommendation, and a decision framework block lays out when building makes sense versus buying. Security and compliance analysis walks through SOC 2 Type II, GDPR, HIPAA, ISO 27001, and DPF, with time-to-certify numbers that favor the buy path.
Three case studies do the proof work: Bilt running FusionAuth on Google Cloud at millions of users, Betty Blocks with 10,000+ applications on the platform, and WeRoad migrating off Auth0 for cost and GDPR reasons. An FAQ block covers control, customization, vendor lock-in, and speed to production. A self-service section closes with docs, sandbox, migration guides, and example code.
Dimension breakdown
Page H1 asks a decision question while four of five ads lead with the resolved promise 'Identity built for modern teams.' The WTD savings variant lines up better but still does not see its hook echoed in the hero.
Below the fold the page delivers what the ads imply: control, self-hosting, compliance, TCO comparison, and three customer proof points. The substance is there; only the hero framing drifts.
Capture metadata shows a trust-heavy, calculator-driven page with the FusionAuth dark header and orange accent. No ad creative images were attached in this audit, so visual-tone alignment is inferred from copy and capture metadata only.
Visitors orient via the FusionAuth logo and auth-related stats, but a click from 'Identity built for modern teams' lands on a different mental frame. The WTD ad gets a cleaner scent path than the retargeting variants.
Top fixes
Echo the dominant ad promise in the H1
Four of five LinkedIn ads run the headline 'Identity built for modern teams.' The page should reuse that exact phrase in the hero so visitors see the message they clicked on instead of a build-vs-buy decision question.
Should You Build or Buy Authentication?
Identity built for modern teams, without building it from scratch
Continue the ad body copy in the subhead
The ads promise 'total control over your user's auth experience, without having to build it from scratch.' Repeating that line in the subhead reassures visitors they reached the right page before they engage with the calculator.
Dedicated architecture. Self-hosted or on FusionAuth cloud.
Total control over your user's auth experience, self-hosted or on FusionAuth cloud.
Surface the savings claim for the WTD ad variant
The 'Your auth might seem free' ad sells a savings story. Promote the TCO savings figure ($1M+ versus building in-house over 3 years, per the page's own calculator) into a hero supporting line so this ad variant lands on a matching headline.

FAQ
How many ads point to fusionauth.io/buildvsbuy?
We pulled 5 ads from the LinkedIn Ad Library pointing to this page. After deduplication they collapse into 2 unique copy variants: a retargeting variant headlined 'Identity built for modern teams' and a WTD account-list variant headlined 'Your auth might seem free (Except for the 3 engineers maintaining it…).'
Why does the page score a C on message match?
Offer continuity is strong, but the hero H1 asks a decision question instead of echoing the ad's resolved promise. Headline match is the weakest dimension at 5.5, which drags the weighted overall score down to 6.4.
What is the single highest-leverage fix?
Rewrite the H1 from 'Should You Build or Buy Authentication?' to 'Identity built for modern teams, without building it from scratch.' That puts the dominant ad promise in the first thing visitors read.
Does the page deliver on the offer once visitors scroll?
Yes. The TCO calculator, decision framework, SOC 2 and GDPR proof, and three customer case studies (Bilt, Betty Blocks, WeRoad) all reinforce the ad's 'discover FusionAuth' invitation. The substance is there; the hero framing is the gap.
