posthog.com homepage teardown: 61/100

Landing page examples › SaaS › posthog.com

The hero headline "Your product's context layer" is a jargon slogan that doesn't say what you get, and the first screen splits attention across a carousel, a sidebar of 30+ links and a cookie popup that covers part of the offer.

We ran posthog.com through PageCritic's landing page audit. It scored 61/100, #10 of the 11 SaaS landing page examples we scored (average 70) and #63 of all 79 homepages in our ranked list. Its strongest area is Speed & SEO (80), and its weakest is Clarity (45).

Audited on 2026-10-24 from desktop and mobile screenshots plus the page's HTML. The scores are an AI's opinion of conversion best practices, not measured conversion rates, and posthog.com didn't ask for this review. The page may have changed since.

Top 3 issues, with fixes

1. Headline is a slogan, not a result

"Your product's context layer" names a category but no outcome, so a visitor landing from search or an ad can't tell what they'll gain in the first few seconds.

Fix: Replace the H1 with a headline that states the result, e.g. "Find out why users drop off, and fix it faster", and move "context layer" into the subheadline.

2. What the product is is hard to guess

The subheadline "PostHog ingests and stores your analytics, errors, replays, and business data so you and your agents can query and act on it" is abstract; 'ingests' and 'context' are internal vocabulary for most buyers.

Fix: Lead the subheadline with the plain category: "PostHog is an all-in-one product analytics platform: session replay, feature flags, error tracking and A/B tests in one tool."

3. Features listed, benefits missing

The three tabs "Ask PostHog anything", "Give agents product context" and "Ship with PostHog" name capabilities, not what changes for the visitor's product or revenue.

Fix: Rewrite each tab label as an outcome, e.g. "Find why signups don't convert", "Let your AI agent see real user behaviour", "Catch and fix bugs before users report them".

What the posthog.com homepage does well

The headline is short (4 words) and set large at 36 px, so it is the first thing read.
A clear primary button, 'Ask PostHog anything', sits in the first screen on desktop, and 'Install with AI' appears on phone.
'No credit card required' sits right under the offer, which lowers the risk of trying the product.
