FAQ's

Questions we hear every time.

How does Double use AI?

We use AI to speed up research, testing and iteration. We don't use it to replace strategy or pump out generic copy. It helps us read behaviour, draft and test variations, and spot patterns faster, which means more of our senior time goes on the thinking that moves your numbers.

Do you only build on Webflow and Shopify?

They're our two specialist platforms, because they give you fast, flexible sites you own and can update without a developer on speed dial. On another platform? Tell us, and we'll give you a straight answer on whether moving is worth it, or whether we can work with what you've got.

What happens after launch - do you stick around, or disappear?

We stick around. Launch is where the value starts building, so we keep measuring, testing and refining against your main metric. You get the option of an ongoing reporting, support, upgrades and testing programme, not just handover email. Bill for the build, disappear before anyone checks whether it worked: that's the standard agency move, and it's the opposite of how we run. A site that gets a little better every quarter is worth far more to you than one that peaks the day it goes live and slowly fades.

Do you write the copy, or is that on us?

We write it. Copy, UX and CRO are part of every build. We're not going to hand you a gorgeous empty template and ask you to fill in the words. We sit down with you and your sales team, then write the messaging that does the converting. Copy is where most sales are won or lost, so it's the last thing we'd hand back to you. The objections and questions your sales team fields every day go straight into the page. Your site does the educating before anyone picks up the phone, and the leads who do get in touch already know what you're about.

What if we launch and the numbers don't move?

Then we keep working the problem. Launch is the start of the optimisation, not the end of it. We run A/B tests on headlines, CTAs and form fields, find what's dragging, and refine until the number moves. The measurement is baked in from day one. No agency worth its fee can guarantee you a specific result, and you should be suspicious of any that tries. What we can promise is that we won't vanish at launch and call it a win. If the data says something's off, we act on it. That's the whole reason we build on behaviour instead of opinion.

Who actually does the work — the team I meet in the pitch, or juniors after I sign?

The people who pitch you are the people who build your site. Double is a small senior team, so you deal directly with the strategists, designers and developers doing the work, not a sales rep parked in front of a room of juniors. The old bait-and-switch, dazzling pitch then your project quietly handed to whoever's free, is one of the most common complaints about agencies. It's why we keep the client list short on purpose. Senior people on every project, and a direct line to whoever's making calls about your site.

What results can I realistically expect, and how soon?

Brands we work with usually land conversion rates of 2–12% on qualified leads and 150–400% better return on ad spend. You'll generally see things move inside the first quarter, once the testing compounds and the new messaging settles in. Results depend on your traffic, your offer and your market, so we won't promise a number we can't tie to your actual situation. Be wary of anyone who does. What we will promise is the process and the reporting. You'll always know what's working and what we're doing next.

Will we lose our Google rankings and traffic when we relaunch?

Not if the migration's done properly. We hold onto your SEO equity by mapping every existing URL, setting up 301 redirects, and keeping the pages and content that already rank. Handled right, your traffic holds through launch and climbs as the new structure and copy take effect. This question exists because somewhere out there is an agency that rebuilt a site in a vacuum and wiped out months of organic traffic overnight. We don't work like that. There's a pre-launch crawl, a full redirect map, a staging site you sign off on, and monitoring for the weeks after go-live, so anything that slips gets caught early.

What does a high-conversion website cost?

Pricing depends on scope, but you get a fixed project price up front. No hourly meter, no surprise invoices. A landing page or conversion upgrade typically starts around $5,000, and a full build with copy and creative runs $40,000–$80,000+. You'll know the number before any work begins. Scope creep is what wrecks most agency relationships, so we sort it on day one. The proposal spells out what's in and what's out. Want to add something halfway through? We price it separately and you decide. It never just turns up on the invoice.

How long does a high-conversion website build take?

Most builds take about 6–12 weeks from kickoff to launch. It comes down to how many pages you need and how ready your content and brand assets are. A landing page set or conversion upgrade is quicker. A full rebuild with new copy and creative takes longer. You get a dated timeline before we start. The thing that actually slows projects down is usually sign-off, not us. When feedback and content stall on your side, the clock stalls with them. So we set milestones and decision deadlines at the start and keep things moving. That's how the timeline holds.

Do I need a full website rebuild, or just a conversion upgrade?

Probably not a full rebuild. Plenty of brands just need new landing pages, or a few CRO fixes on what they've already got. We audit your current site, find where conversions are breaking, and recommend the smallest fix that moves the number rather than the biggest project we can sell. We'd rather tell you to fix three pages than talk you into a fifty-page rebuild you don't need. A full rebuild earns its keep when the structure, the messaging or the platform is actively holding you back. When it isn't, we'll say so. Either way, you leave the audit knowing where your conversions are leaking.

Will this be another pretty website that doesn't convert?

Because we start with the conversion problem, not the design. Every page is built around a decision your buyer needs to make, and we measure it against one number: leads or sales. A site that looks great but doesn't move that number isn't finished, however nice it is to look at. It's the question we get most, and fair enough. A lot of agencies sell you a look and hope the results turn up later. We do it the other way round. First we work out where your current visitors are bailing and why, then we design to fix that specific leak. The conversion target goes into the scope before we touch a layout, and we report against it once you're live. Good-looking is the floor, not the win.
