The Website Conversion Checklist: Every Factor That Actually Affects Your Leads

We had a client who spent £1,500 on Google Ads and got zero enquiries. Nine-second load time, no clear call to action. The gap between a 2% site and an 11% site isn't luck — it's a specific, checkable list of things, and that client's site failed almost every item on it.

Business owners often ask us if their website is "doing well." The honest answer depends on a number most people have never looked at — and once they see the gap between an average site and a great one, the question changes from "is it fine?" to "what's actually missing?"

The current median website conversion rate sits around 2.35% across industries. The top 10% of sites convert at roughly 11.45% — a gap that's widened significantly in recent years. For small business service sites specifically, 3–5% on contact form submissions is a solid working target, though urgent-need trades like plumbing or pest control can see 12–16%, since someone with an emergency isn't comparison shopping the way someone considering a bigger, considered purchase would.

This post pulls together every factor that actually moves that number — with links out to the detailed guides on each one, so you can go deep wherever your site needs the most work.

Homepage and First Impressions

The homepage hero is still the first thing we check on any site — it decides more of that conversion gap than almost anything else on this list. A visitor forms an impression in seconds, and everything downstream of the homepage depends on whether that first impression told them clearly what you do and who it's for.

We've covered this section by section in the anatomy of a lead-generating homepage — hero, trust signals, services snapshot, call to action, and the footer nobody thinks about.

The Features That Capture Leads Once They're Convinced

A great homepage gets someone interested. What happens next — the contact form, the live chat, the lead magnet — determines whether that interest turns into an actual enquiry.

We've broken these down in detail in 5 website features that actually generate leads, including two popular features that quietly do more harm than good.

Trust and Pricing

The £1,500 ads client's site had no pricing indication and buried testimonials on a page nobody clicked. Both problems, on their own, are small. Together, they're most of the gap between an average site and a good one.

Pricing transparency in particular is worth calling out on its own — research consistently shows price is one of the single most important pieces of information visitors want, and hiding it is a common, avoidable way sites lose people before they ever get in touch. We cover this in full in why hiding your prices is costing you customers.

Being Findable in the First Place

None of the above matters if the right people never find your site to begin with. If your business depends on customers nearby finding you, local search visibility is often the single biggest lever available — bigger than any on-page tweak.

We've covered what this actually involves in what is local SEO, and does your small business need it.

Getting the Fundamentals Right

A few factors don't have their own dedicated post yet, but belong on this checklist regardless.

Page speed. Nine seconds to load on mobile was the real problem behind that £1,500 ad spend — not the ads, not the targeting. A slow site quietly disqualifies visitors before they ever get the chance to read a word of copy. Most visitors won't wait around to find out if the content was worth it.

Information trapped in PDFs. We still see service details and pricing trapped in a downloadable PDF instead of on the actual page. Every extra click and load time between a visitor and the information they want costs you a percentage of them. If it matters enough for a visitor to want it, it belongs on a webpage, not buried in a download.

Navigation that matches how customers think. If your menu is organized around your internal service tiers rather than how customers describe their problem, visitors won't recognize themselves in it. We've written about this specific pattern in is your website organized around your business, or your customer's problem.

What's Actually Realistic for Your Business

It's worth being honest about what a "good" number looks like, because the broad averages can be misleading. A 2–5% conversion rate is typical for most small business websites. Urgent, local trades often see much higher rates, simply because the customer has already decided they need help right now. Bigger, more considered purchases — the kind that take weeks of research — tend to convert lower, even on a genuinely well-built site.

The right question isn't whether your number matches some generic industry average. It's whether your site is doing everything on this checklist — and if it isn't, which item is the most obvious gap to close first.

The Bottom Line

Conversion isn't one big decision — it's a checklist of smaller ones: a clear homepage, features that actually capture leads, visible pricing, findability, and the fundamentals like speed and accessible information. Work through each section above, and the number that matters — leads, not just traffic — tends to follow.
