You don't need a data warehouse to know which ads bring new customers. HonestTag checks your ad platforms' claims against your real orders for free, and paid plans send purchases marked new or returning to more platforms. Polar Analytics is a data platform for ecommerce: a warehouse you own, dashboards, multi-touch attribution, incrementality testing and an AI Operator in Slack.
- Catch the sales your pixel misses. Orders come straight from Shopify, server to server, and paid plans send purchases from HonestTag's servers, where a browser blocker can't reach them.
- A clean signal for your bidder. The platforms you send to get each verified purchase, new customers marked as new, so you can point bidding at new buyers.
- Stop paying for buyers you already have. Every delivered purchase is marked new or returning, so your campaigns can go after new buyers instead of repeat ones.
- Proof when someone asks. Open an attributed order to see the click, the match and any refund behind it. Paid plans
- Live in minutes, one flat price. A Shopify Web Pixel with no theme edit, and paid plans priced by your sales, with no per-order fee.
- Know what to scale. A weekly scale, hold or cut call per channel and campaign, with the numbers behind it, or "No verdict" when the data is thin. Start free beside your current tracking.
Stop guessing which ads bring new customers, and give Meta and Google a new-customer signal you can bid on. HonestTag sends verified purchases to Meta, Google and 7 more, each buyer marked new or returning. Start free beside your current tracking.
Where Polar Analytics wins
- A warehouse you own, with a dedicated Snowflake database, unlimited users and unlimited history, per its pricing page.
- Lift tests with a data scientist, attribution that credits TV, podcast and direct mail, and Klaviyo audiences.
- Amazon and other sources beside Shopify, and 113 five-star reviews out of 116 on its listing.
If that is the job, Polar Analytics is built for it.

What you get with HonestTag that Polar Analytics doesn't
- Claims checked, not modeled. HonestTag puts each platform's claims beside the new customers your orders show, by one stated rule.
- Delivery to more platforms. Polar's Advertising Signals sends conversions to Meta and Google Ads. HonestTag sends to those and 7 more.
- New or returning on every purchase. We found no Polar page that describes marking delivered conversions this way.
- Start free. The Mirror plan is free at any store size and the Starter plan is $49 a month. Polar's Core Plan starts at $750.
Different meters
Polar prices on store size. Its listing shows the Core Plan "from $750" a month, "Pricing based on online GMV," with discounts for annual terms, and notes that charges "may be billed by Polar Analytics separately from your Shopify invoice." Its pricing page asks for your annual gross merchandise value and prices Advertising Signals on request.
HonestTag paid plans follow your trailing 30-day sales. $5K-$50K: Starter plan, $49. $50K-$250K: Truth plan, $99. $250K-$1M: Truth+ plan, $199. $1M-$3M: Scale plan, $499. $3M+: Scale+ plan, $999. The Mirror plan is free at any size.
No paid plan has a per-order fee or an overage charge. A store's first paid plan starts with a 21-day free trial. Current terms live on the pricing page.
Run both
Polar's dashboards and warehouse can stay exactly as they are. Start HonestTag free to add a check of each platform's claims against the new customers in your orders.
Keep one purchase source for each pixel and ad account. If Polar's Advertising Signals already sends conversions to Meta or Google Ads, do not point HonestTag at the same pixel or conversion action. Read duplicate purchase events and the alongside guide first.
Frequently asked questions
Do I have to remove Polar Analytics?
No. Keep Polar running while you evaluate HonestTag beside it. The free Mirror plan sends no purchases to any platform, so it cannot add a second purchase event.
Will two tools double-count?
They can if both send the same purchase to the same pixel or ad account. Pick one purchase source for each platform. Duplicate purchase events explains why, and the alongside guide explains the setup.
Is Polar Analytics cheaper?
No. Polar's Core Plan starts at $750 a month, based on online GMV, against $49 to $999 a month for HonestTag's paid plans. Polar's price covers a data warehouse, dashboards, attribution and an AI Operator. HonestTag's covers claims checked against your orders, new-customer conversions, order proof and delivery to the platforms you connect.
Polar already has attribution. What does HonestTag add?
Polar's attribution is multi-touch, across your channels. HonestTag does not model credit: it puts each platform's own claim beside the first-click new customers your store recorded, and on paid plans sends every verified purchase server-side, marked new or returning, with proof for each attributed order.
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, Reddit or Microsoft Advertising?
Yes. Paid plans deliver to Google Ads, Meta, Klaviyo, Microsoft Advertising, TikTok, Google Analytics 4, Pinterest, Reddit and OpenAI Ads, the ones you connect.
