Competitor Price Tracking Extension: Spot Changes Early

Why the store listing won't tell you the price

We checked store names, summaries and manifests for price words and payment hosts across 61,820 extensions on 3 Oct 2026. Just 572 showed any paid evidence, under 1 percent. Big paid tools like Grammarly and Loom came back blank, even though both sell paid plans.

The reason is simple. Google retired Chrome Web Store payments, so paid extensions take money on their own website, usually with Stripe or Paddle. The store listing is a shop window with no price tags. The checkout, and every price change, lives on the publisher's site.

Paying customers are handled on the website. That is where price changes show up first.

That also means you can't judge a niche's money from the store alone. Our guide to paid versus free extensions shows how to estimate it from other signals.

Which listing clues hint at a price change?

Even without a price, the listing changes when pricing does. These are the clues worth watching:

Permission changes are the most reliable clue, because a licence check needs a host permission to call home. We explain how to read them in what permission changes tell you.

How to set up a competitor price tracking extension routine

This takes about twenty minutes a month for five rivals.

1. Find each pricing pageOpen the rival's store listing, follow the website link, and find the pricing page. Note the URL in a sheet.
2. Save a dated copySave the page as a PDF or screenshot, named with the rival and today's date. Do this once a month.
3. Write the key facts in the sheetPlan names, monthly and yearly price, limits on each plan, and what the free plan includes.
4. Compare with last monthMark anything that changed: a new plan, a price change, a limit cut, a feature moved to a higher plan.
5. Log changes in one lineDate, rival, old value, new value. This log is what you will read in six months.
6. Check the listing between savesOnce a week, glance at the clues in the table above. If two show up, save the pricing page early.

If you track rivals' listings with a tool, the clue checks happen for you. Ext Watch keeps every listing change with its date, so a description rewrite or new permission shows up without you looking.

A worked example: email finder extensions

The email finders niche is a good test, because nearly every tool in it is paid, and almost none show a price on the store. In our crawl on 3 Oct 2026 it held 138 extensions, 37 of them with more than 10,000 users, rated 4.59 on average.

Say you are building a cheaper email finder. Here is how the routine plays out:

• Month one. You save the pricing pages of all four, plus their free plan limits. Apollo puts Free in its listing name, so its free plan is part of its pitch. If that word ever leaves the name, it is a strong clue.
• Week three. SignalHire ships a new version. You glance at its description: no new pricing words, no new permissions. Nothing to do.
• Month two. You compare. Say one rival cut its free credits in half. You note it, then read its newest reviews over the next few weeks.

That last step is where the value is. A cut free plan with angry reviews is an opening for you: your listing can lead with the generous free plan they took away.

Notice what the example did not need: no scraping of reviews, no logging in, no special tools. Four saved pages a month, a sheet with a few columns, and a weekly look at the listings were enough to catch the change and decide what to do about it. The hard part is not the method. It is keeping the habit going through the months when nothing changes, so that you have a clean before and after when something finally does.

How to read a price change

A saved change is only useful once you know what it means. Read it alongside the rival's ratings and reviews:

• A price rise with steady ratings suggests customers accepted it. You may have room to raise your own prices.
• A shrinking free plan followed by angry reviews suggests room for a kinder alternative.
• A new top tier with team or business words suggests they are moving upmarket, which can leave smaller buyers underserved.
• A price cut often follows a strong new rival. Check who launched in the niche recently on our new launches list.

Reviews on the Chrome Web Store are the place to see that reaction. Sort by newest and read the one and two star reviews from the weeks after the change. Our guide to reading store reviews shows what to look for.

No old copy, no proof of a change.

Common mistakes when tracking competitor prices

Most tracking efforts fail in the same few ways. Avoid these and your log will stay useful for years.

Saving only the headline price. The monthly price is the least likely thing to change. Limits move far more often: credits per month, seats per plan, exports per day. A rival that keeps its price but halves its limits has raised its price. Write the limits down every time.

Forgetting the yearly price. Many publishers change the yearly discount without touching the monthly price. A move from two months free to one month free is a rise of about 8 percent for yearly buyers, and nobody announces it.

Ignoring regional prices. Some pricing pages show different prices by country. Save the page from the same country each time, or note where you saved it from, or you will log changes that never happened.

Tracking too many rivals. Ten rivals saved carefully beat forty saved sloppily. Pick the ones your buyers actually compare you with. If you are not sure who they are, the AI assistants and other niche pages on Ext Watch list the largest extensions in each niche with their ratings.

Reacting too fast. A price change in week one tells you what the rival hopes will happen. Reviews in weeks two to six tell you what did happen. Wait for the second part before you change your own pricing.

Never writing down why. When you do change your own price in response, add a line to the log saying which rival change prompted it. Six months later, that line is how you learn whether chasing rivals was worth it.

What tools help track competitor prices?

You have three options, from cheapest to most complete:

1. A sheet and a calendar reminderFree, slow, and fine for up to five rivals.
2. A page change monitorGeneral website change tools can watch a pricing page and email you on change. They are noisy on pages with rotating banners, so watch only the price table if the tool allows it.
3. A store tracker for the cluesTools that save store listings over time catch the listing clues for you. For the trade-offs, see our Chrome Stats review and our guide to competitor tracking.

We're biased: Ext Watch is adding polite checks of publisher pricing pages, each saved with a date and source link. Until then, a monthly saved copy does the same job for a few rivals. You can see what each of our plans includes on the pricing page.

Save that first copy today. Next month it becomes a comparison.
