EComposer vs PageFly: Store Extras or Testing on a Slider

The short answer: count your live pages, sections and templates first, because both tools charge by that count. With about 40 live and split tests running, EComposer's Pro plan at $49 a month on monthly billing holds 50 and includes A/B testing, while PageFly's Optimize slider reaches $59 at 40 slots. With 20 or fewer, PageFly's Optimize at $39 is the cheaper way to test, and adds heatmaps on 10 pages that EComposer's plan list does not mention (EComposer pricing, PageFly pricing, checked on 26 October 2026).

Count before you choose:

1. Your live count, priced on both. For example, 12 live pages and sections with no testing: EComposer Standard holds 15 for $25 a month, and PageFly's Builder slider moves in steps of five, so 12 needs 15 slots at $34. Over a year that is 12 x $25 = $300 against 12 x $34 = $408, per the EComposer and PageFly pricing pages.
2. The apps already on your store. EComposer's paid plans bundle store tools many shops buy separately: Standard lists seven built-in extensions, sticky add to cart and image compression among them, and Pro lists the full set, from back-in-stock alerts to volume discounts, plus popups and post-purchase upsells (EComposer pricing). Note which of those you pay for today; they change the sum.
3. The tracking a test will need. EComposer's split tests need Google Analytics 4 connected, the Shopify Pixel switched on and the app embedded in the theme before the first campaign (A/B testing article). PageFly reports from its own built-in analytics from Builder up. Whichever you pick, take four weeks of orders per visitor from Shopify as the baseline.

What tips it

Tiers or slots

EComposer sells three sizes: 15 live items on Standard, 50 on Pro, unlimited on Premium at $129 a month, and a page, a section and a product template each take one (EComposer pricing). PageFly prices each step of five slots at $5: Builder runs $24 to $34 and Optimize $39 to $94, and only Accelerate at $99 drops the count (PageFly pricing). From 30 to 50 items with testing, EComposer's flat $49 is level with or below PageFly's slider, which reads $49 at 30 slots and $69 at 50; past 50, EComposer needs Premium at $129 while PageFly tops out at $94 for 75.

Testing and seeing

PageFly's Optimize plan adds A/B testing, heatmaps on 10 pages, a sales funnel view and section performance in the same app, from $39. EComposer's testing starts on Pro and runs through Google Analytics 4; its plan list mentions page analytics but no heatmaps. A team that wants to watch where shoppers stop scrolling gets that only from PageFly of the two.

Pages, or pages plus store tools

EComposer is the one to pick if you would otherwise install separate apps for a sticky cart, back-in-stock alerts, bundles or a spin-wheel popup, because Pro carries them. Its post-purchase upsells come with a fee on Pro, covered in How to use EComposer. PageFly keeps to pages and conversion data.

One AI step: the audit suggests, the merchant applies

PageFly's AI Page Checkup is free on every plan, Free included. Open a saved page, run the scan, and read the findings in order: more than 20 structural checks, such as a missing H1 or alt text or a price far from the buy button, plus 8 AI checks on a full render of the page covering offer clarity, price legibility, review credibility and the returns policy. Heading and alt-text fixes apply in one click; the AI findings name the section to open, and every fix is applied by the merchant, one at a time. EComposer's Page Audit does a similar job inside its editor, scoring SEO and conversion checks and re-running each time you edit.

The person applying the fixes checks what software cannot: whether a "review credibility" note is a design problem or a sign the reviews are thin, whether the offer the audit wants above the fold is the one the ad promised, and how the page reads on a phone. PageFly's own page says the AI checks do not need traffic, so this works on a page before it goes live.

Try both for nothing

Build the next campaign page on both free plans, run each through its audit, publish each at its own URL and split the same ad's traffic by day for two weeks; Shopify's orders per visitor decides it. EComposer's paid trial lasts 7 days without a card, and PageFly refunds within 30 days on any paid plan, so a paid test of either costs little (EComposer pricing, PageFly pricing).

Read EComposer's pricing page with the toggle in mind. It opens on yearly billing, so the first figures a visitor sees, $19, $39 and $103, are annual rates that assume twelve months paid up front; switched to monthly, the same plans are $25, $49 and $129 (EComposer pricing).

Choose EComposer if your job is

• Keeping between 30 and 50 pages, sections and templates live while testing.
• Replacing separate store apps, such as a sticky cart, bundles or back-in-stock alerts, with one builder.
• Adding post-purchase and thank-you page offers from the same app.

Choose PageFly if your job is

• Testing a small set of pages with heatmaps and section data in one place.
• Paying for exactly the slots you use as the page count grows by fives.
• Auditing pages for conversion problems on the free plan before paying anything.

FAQ

Does PageFly offer yearly billing on Optimize?

No. Yearly billing, ten months' price for twelve, is available on Accelerate and Power only; Free, Builder and Optimize are billed monthly (PageFly pricing).

Does EComposer count a product template as a page?

Yes. Its pricing FAQ says a published page, template or section each uses one of the plan's live slots, so Standard's 15 could be 10 landing pages, 2 product templates and 3 sections (EComposer pricing).

Which one has heatmaps?

PageFly, from Optimize: 10 pages, then 50 on Accelerate and unlimited on Power (PageFly pricing). EComposer's plan comparison lists A/B testing and page analytics but no heatmaps (EComposer pricing).
