A buyer's guide for extension developers: what generalists get wrong, the free-to-paid question to ask first, and six questions before you sign.
Why a generalist agency misreads a Chrome extension
Most agencies sell a local playbook: a website, a Google Business Profile, some ads, a review request. None of that fits a Chrome extension. Nobody searches “tab manager near me.” There is no map pack to win and no storefront to photograph. Your users find you in the Chrome Web Store search bar, in a Google search for “best chrome extension for tab management,” in a Reddit thread, or by asking an AI assistant which tool to install. An agency that starts by asking for your business address does not understand where your users come from.
The second miss is the funnel. A click does not become a customer when someone lands on your page. It becomes a customer when they press “Add to Chrome,” accept the permission prompt, open the extension a second time, and later pay for a Pro tier. Google no longer lets you sell paid items inside the store, so the upgrade happens on your own website, outside the listing. A generalist counts installs and calls it growth. Installs that never activate are worth nothing.
The third miss is risk. A broad permission request, the kind that reads “read and change all your data on websites,” scares people into removing the extension before they see it work. A review rejection or a policy update can take your listing offline with little warning. An agency that has never handled a relist, or never rewritten a listing to explain a permission in plain words, will learn on your budget.
Ask this first: how do they lift free-to-paid, not just installs?
One question sorts the field faster than any portfolio. Ask: “Walk me through how you would raise my free-to-paid rate.” A team that knows extensions will talk about onboarding, the first real win inside the tool, upgrade nudges, and lifecycle email. A team that does not will talk about more traffic.
Listen for the store itself. The Chrome Web Store ranks listings on keywords and category, closer to Google Play than to Apple's curated App Store. Your title, description, and category act like on-page SEO for the store's own search engine. A good agency will show you which phrases your listing is missing and what the screenshots and promo tile should say. It should also have a view on when to ask for a rating: after a real win, not on first install, because store ratings are both a trust signal and a ranking input.
Ask, too, what they would do about the store's own review system. Chrome Web Store reviews are public and permanent, and a run of one-star reviews after a bad update sits at the top of your listing for months. A team that knows the store will have a reply plan, a way to prompt happy users after the fix ships, and a release-notes habit that stops the next wave.
Then ask about measurement. Can they connect an install to the campaign that produced it, and follow it to activation and upgrade? If the answer stops at “we track clicks,” you will never know your true cost per paying user.
Where paying users actually come from, in order
Start with the listing, because every other channel dumps traffic onto it. Fix the icon, the first two screenshots, the first sentence of the description, and the plain-language permission note before you spend a dollar on ads. A weak listing turns every click into a browse and a close.
Next is search on the open web and inside AI assistants. People read “best chrome extensions for productivity,” “alternatives to [competitor extension],” and “[category] extension for chrome” articles before they ever open the store. They also ask ChatGPT or Gemini “what is the best Chrome extension for managing tabs?” Content that answers those questions, plus a landing page that earns citations, puts you upstream of the store. Reddit threads in communities where your users already gather often outrank brand sites for these searches, so being mentioned there, honestly and without astroturfing, is part of the job. Local SEO and Google Business Profile do not apply here; skip any agency that bills you for them.
Paid comes third. Google Search and Display campaigns on “[task] chrome extension free” and competitor-alternative phrases produce installs quickly, but they are only worth running once activation is decent. Then lifecycle email: a welcome, a nudge to pin the extension, a message when the user hits the moment the paid tier solves, and a win-back after an uninstall. Store reviews sit last in the order but feed everything above, because a stronger rating lifts both conversion and rank.
Spikes, not seasons, and what a user is really worth
Extensions do not have a spring rush. Demand moves in spikes: a Product Hunt launch, a roundup article that picks you, a competitor raising prices, a Chrome update that breaks the old favorite. Productivity tools also see a lift when people reset habits, at the start of a new year or a new school term. A good agency plans for the spike with a landing page, tracking, and follow-up email ready, so the traffic sticks instead of vanishing the next day. Launch weeks also bring a wave of uninstalls from curious visitors who never needed the tool; an agency should expect that and not treat it as a failure.
Talk about value in the right units. A free install is worth nothing on its own. An active user who opens the extension every day is worth something because they rate, refer, and eventually see the Pro tier. A Pro subscriber is worth months of subscription revenue for as long as you keep them. Put this to every agency: “what does one paying user cost us, by channel?” Cost per install hides the leak between install and upgrade.
Ask how they handle retention math too. Day 1, day 7, and day 30 activity tell you whether onboarding works. If an agency cannot name those checkpoints, they are selling downloads.
Red flags and what you must keep in your own name
Your Chrome Web Store developer account, your ad accounts, your analytics, your email list, and your domain should all stay in your company's name. Some agencies run ads from their own account or build the landing page on a platform you cannot export. When you leave, the history leaves with them.
Watch for install guarantees. Nobody honest can promise a number of installs or a store ranking; the store's search is not something a vendor controls. Watch for “we buy installs” offers, which produce users who never activate and can hurt your rating. Watch for reports that show clicks and installs but never cost per paying user. And watch for anyone who suggests stuffing the description with unrelated keywords; the store treats keyword spam as a policy violation, and a takedown costs far more than the ranking it was meant to buy.
Ask two direct questions. “If we stop working together, what do I keep?” and “Can I see my own dashboards without going through you?” Month-to-month terms are a good sign; an agency confident in its activation and upgrade numbers does not need a year-long contract to hold you.
Six questions to ask before you sign
One: “How would you rewrite my store listing, and which keywords is it missing right now?” Two: “How do you explain a scary permission so people do not uninstall?” Three: “Show me how you connect an install to activation and to a Pro upgrade.” Four: “What is your plan for ‘best chrome extension for [task]’ searches and for AI assistants?” Five: “Who owns the developer account, ad accounts, and email list?” Six: “What happens to the traffic from a Product Hunt launch the week after?”
Compare the answers side by side. Specific answers name the store's ranking inputs, the moment to ask for a rating, and the email that moves a free user to Pro. Vague answers talk about brand awareness.
