Sameness · vs 2 named
How is this calculated?

Your page is half shared.

About half of what your page says, Amplitude also says. You're less same than 6 of the 8 Digital analytics sites scored (category avg 52).

Benchmarked against Digital analytics (the category you chose).
Sameness Index on a 0 to 100 scale, from distinctive at 0 to interchangeable at 100. This page scores 47. PostHog scores 42. Amplitude scores 70. The category avg is 52.

Each named site is scored the same way, against the other 2 in this set, so its tick means the same as your marker. The dashed line is the frozen benchmark average.

  1. Less same than average

    The average Digital analytics category leader scores 52; you scored 47.

    You are 5 points less same than the average Digital analytics category leader.

  2. Closest overlap: Amplitude

    Of the 2 sites you named, Amplitude echoes the most of what your page says. Scored the same way against the rest of the set, Amplitude sits at 70.

    Amplitude is the competitor you sound most like.

  3. Room to own more

    27% of your claim space is ownable: unique, relevant, and hard to copy. 8 of those claims sit in body copy, where few readers reach them.

    27% is ownable, and 8 buried opportunities could help you stand out more.

Do this first

Three changes worth testing first.

Chosen by rule from the comparison with PostHog and Amplitude: the shared claim taking your most prominent space, then the claims only you make that sit too low on the page to be read. Each one links to its claim card.

  1. “The most trusted name in AI analytics”

    PostHog and Amplitude all say it too. Buyers may still need it, but shared ground cannot carry your section — move it lower and give that space to something only you can say.

    Table stakes
    Most of the set says this too.
  2. “Track user journeys end-to-end, from entry to conversion (User Journey Maps)”

    Nobody in the set says this. It sits in body copy, where few readers reach it — worth testing higher up the page; only buyers can tell you whether it lands.

    Surface
    Yours alone. Test it higher up.
  3. “Get lightweight, high-fidelity mobile replay and cross-platform analytics (Mobile Analytics)”

    A claim that is yours alone, filed in body copy. Try it where it will be read before the shared claims are, and let buyers tell you if it moves them.

    Yours alone. Test it higher up.

Try these changes, then test them with real buyers.

This measures overlap. Whether buyers notice is a different question, and only they can answer it.

Why this is not 100 minus the Sameness Index

The index is a weighted composite across six categories, including page structure and visuals. This bar is measured on your claims alone, weighted by where each one sits on the page. Different denominators, so the two never add to 100 and are not meant to.

Where you blend in

Territory you spend prominent space on that the set also occupies. Not every line is one to delete — the question is whether it has earned the space, or whether something only you can say should be there instead.

  • Commodity · 100%Table stakesSection
    Better, faster decisions from trusted insights
    • “so teams can move faster, make smarter decisions, and build AI on a foundation they can trust”

    PostHog and Amplitude all cover this territory. Buyers may need to hear it, but in your section it spends the first impression on shared ground.

    They say
    • PostHog“The data your agents need to make good decisions is already here. Ready to turn 'tell me what happened' into 'here's what to fix next.'”

Whether a competitor could truthfully make the same claim: anyone could, copyable with effort, or hard to copy.
Relevant
Whether buyers decide on this. A unique claim nobody buys on is not ownable.

How this was calculated

Sameness measures how much your claims overlap with the sites compared. It does not measure message quality or whether buyers prefer you.

AI-analyzed: an AI read each page on its own and grouped the claims that say the same thing. No score here was written by a model — every number is computed from those groupings in our own code, with the weights below.

How the score is built
The six category scores, their weights, and what a high score in each one means
CategoryWeightYoursWhat a high score means
Messaging
Category framing, who it is for, and the outcome promised
30%50The most expensive kind of sameness. A buyer cannot tell what job you do that the others do not.
Claims
Attribute and benefit claims — speed, ease, quality, ROI
30%50Every shared claim is a line already read on another tab. Cut the ones nobody owns and spend the space on something they cannot.
Features
Capabilities and functions the page lists
15%26Expected in a mature category, and the least alarming of the six. Feature parity is normal; leading with it is the mistake.
Proof
The kinds of evidence offered: customer logos, numbers, testimonials, case studies, badges
10%55Same kinds of proof as everyone means the proof stops working as proof. It is scored on the kind of evidence, not on which customers are named.
Structure
Section order, navigation, CTA language and placement
10%61The generic SaaS template — hero, logos, three-feature grid, testimonial, CTA. Familiar is not the same as memorable.
Visual
Palette family, imagery style, layout patterns
5%35Weighted lowest on purpose: buyers rarely decide on this. Worth knowing, rarely worth fixing first.

Each site was read on its own first, with no knowledge of the others, so your page gets no benefit of the doubt a competitor’s does not. A category nothing could be measured for drops out and the rest are re-weighted, rather than counted as zero.

What it cannot tell you

The index can find where two pages converge. It cannot say whether a buyer would notice, or which of your reasons to buy actually land. A single check also moves several points between runs, so read the band and the ranking, not the last digit.

Your highest-impact changes

  1. 1
    Table stakesYour section copy says “The most trusted name in AI analytics”.

    PostHog and Amplitude all say it too. Buyers may still need it, but shared ground cannot carry your section — move it lower and give that space to something only you can say.

  2. 2
    Table stakesYour section copy says “Pizza Hut, JetBlue, Adobe, KeyBank, Mammut, Sprout Social, iHerb, Papa John's, Newell Brands, The Farmer's Do…”.

    Keep the fact, lose the position: postHog and Amplitude all say it too, and your section is spending its first impression on the same territory as theirs.

  3. 3
    Table stakesYour section copy says “so teams can move faster, make smarter decisions, and build AI on a foundation they can trust”.

    This is the set's common ground — PostHog and Amplitude all say it too. It will not set you apart wherever it sits, and in the section it costs you the one place a distinctive claim would be read.

  4. 4
    Surface“Track user journeys end-to-end, from entry to conversion (User Journey Maps)” is yours alone, and buyers weigh it.

    Nobody in the set says this. It sits in body copy, where few readers reach it — worth testing higher up the page; only buyers can tell you whether it lands.

  5. 5
    Surface“Get lightweight, high-fidelity mobile replay and cross-platform analytics (Mobile Analytics)” is yours alone, and buyers weigh it.

    A claim that is yours alone, filed in body copy. Try it where it will be read before the shared claims are, and let buyers tell you if it moves them.

  6. 6
    Surface“Trigger targeted guidance the moment users begin to struggle (Guides and Surveys)” is yours alone, and buyers weigh it.

    No competitor page makes this claim. Today it is in body copy; it is a candidate for the space the table-stakes lines are taking.

  7. 7
    Surface“Pinpoint wins and friction to recover revenue lost in key paths (Conversion Funnels)” is yours alone, and buyers weigh it.

    The rest of the set has nothing on this ground. Buried in body copy it does no work; higher up it is the one line a comparing buyer cannot find elsewhere.

  8. 8

The only way to know if it matters.

This report can tell you where your messaging overlaps. It cannot tell you whether a buyer would care, or which of your reasons to buy actually land. Put the page in front of real B2B buyers in your target market and ask them.
