HonestTag vs Lebesgue
By the HonestTag team ยท Published September 2, 2026
Lebesgue combines store and ad analytics with Henri. Le Pixel: Attribution adds first-party attribution, server-side tracking and Meta CAPI. HonestTag measures one attribution model with order proof and sends every verified purchase to your configured destinations among Google Ads, Meta, Klaviyo, Microsoft Advertising, TikTok, Google Analytics 4, Pinterest, Snapchat, Reddit and OpenAI Ads, within your plan's simultaneous-delivery limit.
The honest split
Lebesgue sells store analytics, ad reporting, LTV analysis, competitor tracking, and Henri. Le Pixel: Attribution adds several attribution models and customer journey views, server-side tracking with Le Enricher, and Meta Conversions API (CAPI) integration.
HonestTag's free Mirror is a read-only scorecard of Google Ads, Meta, Microsoft Advertising, TikTok and Criteo claims next to Shopify orders. Paid HonestTag matches each order to the first recorded ad click, classifies the buyer as new or returning, stores order proof, and delivers every verified purchase to your configured destinations among Google Ads, Meta, Klaviyo, Microsoft Advertising, TikTok, Google Analytics 4, Pinterest, Snapchat, Reddit and OpenAI Ads, within your plan's simultaneous-delivery limit, marked new or returning.
A send is counted after platform acknowledgement. Meta reports an accepted count for each batch. Google accepts a request first and reports row-level results later, so HonestTag keeps each accepted request open for up to 26 hours and corrects the record after Google reports those results. TikTok acknowledges a batch without confirming each event. HonestTag counts a batch as delivered only on TikTok's documented success code, return code 0. Any other response is marked partial or handled as an error, and is not counted as delivered.

When Lebesgue fits
You want store analytics, competitor tracking, Henri, and several attribution views. Le Pixel adds customer journeys and first-party attribution to that product.
When HonestTag adds a different job
You want a fixed first-click new-customer reporting rule, proof tied to the Shopify order, and a named reason for a blocked conversion. You want every verified purchase sent to Google Ads as well as Meta, marked new or returning.
Different product layers
Lebesgue sells analytics plans and a Le Pixel: Attribution plan. HonestTag's free Mirror is read-only. Paid tiers add order proof, reporting, and delivery to Google Ads, Meta, Klaviyo, Microsoft Advertising, TikTok, Google Analytics 4, Pinterest, Snapchat, Reddit and OpenAI Ads. Current HonestTag terms live on the pricing page. Lebesgue maintains its current package shape on its pricing page.
Run both
Lebesgue can keep providing its analytics and model views. If its enrichment sends Meta purchases, choose one Meta optimization feed before HonestTag starts delivery. Follow the alongside guide.
Frequently asked questions
Do I have to remove Lebesgue?
No. Keep Lebesgue running while you evaluate HonestTag beside it.
Will two tools double-count?
They can if both send the same purchase independently. Pick one optimization feed in each ad platform. The alongside guide explains the setup.
Why are HonestTag's numbers smaller in week one?
HonestTag starts at zero and does not invent click history from before installation. Give the records about 30 days to build before comparing totals.
Does HonestTag deliver to Pinterest, Snap or Microsoft Advertising?
Pinterest, Snapchat, Reddit and Microsoft Advertising, yes. HonestTag's public delivery destinations are Google Ads, Meta, Klaviyo, Microsoft Advertising, TikTok, Google Analytics 4, Pinterest, Snapchat, Reddit and OpenAI Ads.
