It climbed from 940k to 190k in a month, but only by changing its address: Shopify pop-up app BoostPop

boostpop.app went from 940k to 190k in global rank within a month, looking like a new site taking off. Digging in, it turns out a Shopify pop-up app listed 2021 years ago changed its backend API domain, and traffic from thousands of stores moved with it. The app itself has had no new reviews since July. It's not worth copying, but two things are worth noting: how to spot this kind of fake growth, and how a small developer survives in a crowded category by being "30% cheaper than the leader."

A domain registered in June

In 2026 June 26, Tel Aviv studio AdPerfect registered boostpop.app (per domain registration records). The day before, an article signed "Eran Betzalel, founder" was already live on the domain: "BoostPop vs Pop Convert," a tier-by-tier price comparison whose conclusion is restrained: "this is a comparison between two solid options, not a one-sided verdict."

BoostPop is not a new product. It is a pop-up app for Shopify stores: email-capture popups, top announcement bars, spin-to-win wheels, and social proof like "someone just bought." The Shopify app listing shows 2021-11-17 listed, 4.8 stars and 181 reviews. The homepage says "16,000+ stores installed," and the founder's LinkedIn says "5,000 active stores." The former is probably cumulative, the latter the current active count (inferred).

In October it suddenly appeared in Tranco's global website ranking: 10-06 first entered the top 1M, ranked 940,141. It kept climbing daily, 11-03 rose to 188,657 and stopped, while 11-05 was 192,844.

Why the ranking rose: the traffic didn't come in new, it moved over

Put the two lines side by side and it's clear:

One falls, the other rises, and the timing matches. Looking at the technical side: api.boostpop.app and adperfect.shop resolve to the same server (137.184.240.16). Opening several stores using this app (Kameo Shop in Lebanon, Natural Health World in the UK, etc.), the popup script embedded on each page calls only one external address: api.boostpop.app.

In other words, every store running BoostPop makes its browser request this API once per page view. Part of the global ranking is computed from DNS query volume, and these requests were originally recorded under adperfect.shop. When the switch to the new domain happened in early October, the new domain "appeared" to climb. The ranking is a 30-day rolling average, so the curve flattened once a full month had passed. The new peak is slightly higher than the old domain's best, most likely because the website, dashboard and API are now consolidated under one domain. It doesn't mean more customers (inferred).

Another piece of evidence: in Chrome's real-user visit statistics, boostpop.app doesn't appear in the top 1M in any country. Very few people visit the website directly.

The app itself: a modest older product that has plateaued

• Reviews: about 10 new reviews this year, the latest on 7-20. The total of 11-01 fell to 182,11-04 and then to 181.
• Latest review: German store HAUTTIEF, a user for over a year, reported a bug in July where it conflicted with the Klaviyo signup form. The reviewer 7-20 updated the review: "They found the cause within a few hours. It was a CSS library shared by BoostPop and Klaviyo, and it was fixed the same day." Earlier reviews are mostly one or two words: "super beautiful" (Kameo Shop, 5-08) and "Facil de manejar, muy intuitiva" (Colombia's Fondoshop, 2-18).
• Where merchants are: about 27.5% in the US, 9.5% in the UK, roughly 7.9% each in Italy and Australia, 6.9% in Canada (third-party Shopify statistics site letsmetrix).
• Category ranking: #46 in the Pop-ups category and #25 in Banners. No Built for Shopify (BFS) certification.

A long-tail app listed 2021 years ago that has gradually built a base of small stores through store search and its free tier, now neither rising nor falling.

Where the money comes from

A flat monthly fee tied to the Shopify plan, regardless of traffic:

Source: boostpop.app comparison page; Pop Convert prices as of 10-01. The free tier allows 3,000 popup impressions per month; once exceeded, popups pause and no charges are made automatically. Pro has a 14-day trial. Paid conversion rates and revenue are not public and cannot be calculated: many of the 181 reviews come from users on the free tier.

Who it competes with: one of Shopify's most crowded categories

In the 2026 years since, new apps like PB Spin Wheel and Lucky You have kept coming in, with a few dozen reviews at most. The worst part is the last two lines: Shopify itself and the biggest email provider both give away email popups for free, squeezing this demand from below.

How it gets users

• Organic store search plus a free tier (main channel, inferred): reviews keep praising the "generous free tier" and "works right after install"; found no evidence of paid ads or influencers.
• Renamed to grab keywords: the app name changed from "Sales Popups & Bars" to "Email Popups & Wheel" to target search terms like email popup and spin wheel; the listing also adds "Works with Shopify Sidekick".
• New website for SEO and AI search: the new domain has 53 pages in total: 5 "X alternative" pages, 4 "best popup app" roundups, 2 comparisons, and 4 tool pages (including a "Pop Convert vs BoostPop cost calculator"). Every page is signed with the founder's name, and every number is labeled with its as-of date and source. robots.txt explicitly allows AI crawlers like GPTBot, PerplexityBot and ClaudeBot. Based on Chrome real-visit stats, these pages have not yet brought any visible traffic.

No one has mentioned it on X in nearly 90 days, no press coverage, no public revenue. The only article written about it is "8 Best BoostPop Alternatives" by competitor Vitals, which means a rival is siphoning its traffic.

Two things worth learning

1. When you see "new site rankings skyrocket," first check whether the domain just changed. When a SaaS or plugin switches its API domain, the new domain climbs sharply in global rankings. How to check: open a few users' pages, see which domain the embedded script calls; resolve that subdomain's IP; then check whether old domains on the same IP are declining in a mirrored way over the same period. A curve that "fills up in a month, then flattens" is the typical shape of this.

2. In a crowded category, watch for the moment the leader raises prices. Pop Convert switched from fully free to mostly paid in 2025 May (the free tier now only covers 1,000 visitors a month and 50 subscriptions). BoostPop's response was to price each tier about 30% below it, give a free tier based on impressions that pauses rather than charges when exceeded, and add comparison pages, alternative pages and a cost calculator to capture searches for "Pop Convert is too expensive." This tactic can keep a small app alive, but based on its review curve, it's not enough to make it grow.

If it were you

Verdict: don't follow. This is an old app that never took off; the ranking rise is a domain-switch illusion. Its Shopify popup category has rivals with thousands to nearly ten thousand reviews at the top, and Shopify and Klaviyo give the basics away for free underneath.

Who it's for: developers who already have an app in the Shopify ecosystem and want to study the playbook of "undercut the leader on price after they raise prices + comparison pages + pages written for AI search" — treat it as a textbook.

Who it's not for: anyone starting from scratch to build a Shopify popup, announcement bar or spin-wheel app. TA Banner Slider, launched three years later, has already left it behind, and you'd be the N+1th entrant, competing with free built-in platform features.

How to do it: if you must build on Shopify, don't build a generic popup. Find a category where the leader has just raised prices or cut its free tier, and enter using BoostPop's price-comparison-page approach; or build in the part beyond popups that platforms and email providers don't give away free (for example, a conversion tool for a specific vertical industry).

How to get users: Shopify store search is the main channel, so put the terms users actually search for in the name and subtitle. On the website, write "X alternative," "X vs you" and a cost calculator, label every number with its date and source, and allow AI crawlers.

When to move: there's no window here; this isn't a time-sensitive opportunity.

What would show this read is wrong: ① BoostPop's Shopify reviews resume steady growth over the next 60 days (say, more than 5 a month), which would mean the rename and new site are working; ② boostpop.app enters the top 1M in Chrome's real-user visit stats, which would mean the 53 pages on the site are actually bringing people; ③ Pop Convert raises prices sharply again or drops its free tier, suddenly widening room for a low-cost alternative.
