B2B Conversion Rate Optimisation: More Leads Without a Rebuild
Have your leads been patchy? Maybe they’ve dried up completely, or they never really got going in the first place. Either way, you’re probably trying to work out which part of your marketing is to blame.
Most people check the campaigns first. A new channel, a different agency, another round of ad spend. Meanwhile, it ends up being the page that every single prospect lands on, and it’s the one that hasn’t been touched since the day the business launched. Your poor old homepage.
That’s usually where the problem is. Conversion rate optimisation is the work of fixing it, and it costs a lot less (and moves a lot faster) than rebuilding your entire website from scratch.
On episode 107 of SaaS Marketing Weekly, our founder Ryan sat down with Jamie, our Director of Strategy, to go through the pages that cost businesses the most leads and what you can do to make quick fixes to get that lead volume up.
Listen to Episode 107: Why you don’t need a new website and what to do instead
What is website conversion rate optimisation (CRO)?
Website conversion rate optimisation (CRO) is the systematic process of increasing the percentage of your existing visitors who complete a desired action, such as booking a demo, starting a trial or submitting a form. It extracts more value from the traffic you already have, rather than buying more of it.
You define the conversion event yourself, and it’s worth tracking demo bookings, trial signups and content downloads separately, because each one exposes a different drop-off point.
So if 1,000 people land on your site this month and 10 of them book a demo, your conversion rate is 1%. B2B CRO lifts that figure by changing what sits on the page, which means the messaging, the layout, the product visuals and the calls to action. The 1,000 stays exactly where it is.
Why B2B SaaS websites are going backwards
Something new has started showing up in our onboarding calls. When we ask a new client for access to their CMS, either they have no idea what we’re asking for, or there isn’t one.
Turns out the website was coded and built with an AI tool like Claude with no content management system behind it. This means that no one in a marketing team would be able to upload a blog or change copy on the site without going to the dev team.
AI-built sites are all starting to look the same because they’re all drawn and built from a handful of templates and patterns.
Do you need a new website, or just CRO?
A full website redesign costs £20,000 to £30,000 and has a long build time with approvals and changes along the way.
Honestly, most of the time you don’t even need a full rebuild. If the right people are already landing on your site and not converting, there might just be a couple of pages that need a revamp rather than scrapping the whole site and rebuilding it.
So unless your website is a genuine disaster, or it looks untrustworthy to a stranger, start with tweaks.
When a rebuild is the right call
There are three situations where we’d tell you to rebuild anyway.
- If a stranger’s first instinct is to wonder whether you’re a real company, no amount of copy tweaking will fix that. Your website needs to show that you are a genuine business.
- If there’s no CMS, you’ll be paying your dev team every time you want to change a word, and that cost never goes away. You need a content management system that anyone in your team can jump on and edit when needed.
- If your brand or business positioning has moved on so far that every page describes a product you no longer sell, you’re rewriting the whole thing regardless.
How to tell whether your website is the problem
If your website produces even just one lead a month, then a CRO audit is worth doing. If you aren’t getting a single lead but the right people are landing on your site, then you urgently need to do a CRO audit.
Working out whether the right people are landing takes three tools. Google Analytics tells you what people do when they arrive. Lead Forensics tells you which companies have been on the site. And your LinkedIn ads data tells you exactly who clicked through.
All three answer the same question: is your ideal customer arriving and failing to convert?
Instead of focusing on your next big campaign, shift your focus to building a site that converts better and generates qualified leads from the traffic you’re already paying for.
Get a CRO audit, and why a freelancer may be enough
You might be wondering who is going to do a CRO audit for you. You don’t need an agency for this part. Search Upwork for a CRO audit and you’ll find freelancers who do nothing else. Some charge a few hundred pounds, others £5,000 and up.
What you get back is a deck that works through your site page by page and tells you what to change and why. It’s a one-off rather than a retainer, and for most businesses it’s the cheapest useful thing you can buy.
At Rocket SaaS, we do the findings and the fixes. Our website conversion rate optimisation service is here for you because we believe that your website is the most critical asset for generating leads. And that’s above spending money on LinkedIn and Meta ads or SEO. We work through your messaging, UI and graphics, and make sure strategic CTAs are placed all over your website.
Fix the messaging before the design
SaaS companies are bad at explaining what they do. The copy is too long, there are too many buzzwords, and the reader gets to the bottom of the page still unsure what they’d be buying.
A lot of that comes from copying the wrong people. Big companies like Apple and Slack can afford to be vague because everyone already knows what they sell. But if you’re new in the market or have only been around a short while, vague copy just won’t do it.
Your buyer needs five things from your homepage.
- What you do
- Who it’s for
- What job you help them do
- What problem you solve
- Why you’re different
And the scary thing is that most sites answer none of these questions.
For a proper framework, look at Fletch PMM, the product marketing consultancy founded by Anthony Pierri and Robert Kaminski, or at April Dunford’s work on positioning. Both are free to read.
The hero section
If you only fix one thing on your website, make it this one.
What is a hero section of a website?
A hero section is the area at the very top of a web page, and it’s the first thing a visitor sees before they scroll. On a B2B SaaS site, it usually holds a headline, a short supporting line, a call-to-action button and an image or short video of the product.
The rule for the headline is ten words or less, covering who you are, what you do and the benefit of it. That sounds easy enough, right?
But most people get it wrong. You should be spending hours of your time on this headline. It shouldn’t be something scribbled on a napkin over lunch, or thought up in the last five minutes of a strategy meeting.
Spend the time writing different options over and over. Then run them through AI and see what it does with them. Show the shortlist to colleagues, to your customer success team and to a few prospects, and watch which one people repeat back to you correctly. Someone landing on your site decides within seconds whether to keep scrolling or bounce and go elsewhere. So this line does more work than anything else on the site.
The image or video matters just as much. It has to support what the headline says and point at the next step. A stock photo of a smiling team sitting there as decoration is a wasted opportunity.
Write headings that tell the story on their own
When did you last properly read a website word for word? People don’t read websites, they skim them. Heat-mapping tools like Hotjar show that visitors read the headings first and only come back for the body copy on a second visit.
So your headings have to carry the story on their own. The order that works is the same order a good demo call follows:
- Hero
- The problem
- Your solution
- Social proof
- How you compare against competitors
Stop what you’re doing right now and open your homepage. Read only the headings, top to bottom, and see whether they tell a story someone could follow. Most sites fail at this, because each section was written on its own at a different time. A heading like supercharge your workflow tells a visitor nothing at all.
Make the product shine
There are two ways this usually goes wrong.
The first is when websites slap on a couple of cartoons, like a robot building with bricks. This tells your prospect absolutely nothing about your product. It’s a lazy way to get your website up and going, and no one will convert that way.
The second is pasting a raw screenshot straight out of the product. The font is too small to read, there’s too much detail on screen, and the person ends up zooming in or pressing their nose against the screen to make out the details on a blurry screenshot.
The fix is really simple. Get a designer to strip out the unnecessary detail, increase the font sizes and build a short looping animation of around ten seconds. Slack does this brilliantly. What Slack shows isn’t literally their product UI, and that’s absolutely fine.
Open Slack’s homepage in an incognito window and look at how they present the product. It is worth doing properly, because it is the clearest example of this done well.
If you want a fuller checklist for the rest of the site, we have written up the 10 must-have features for a high-converting SaaS website.
We have found that some founders deliberately hide the product so competitors can’t see it. But a visitor being asked to book a demo of something they haven’t seen has no reason to book it. They need some kind of buy-in to the product before they sit through the demo.
Social proof needs numbers
Vague testimonials do nothing. Great to work with and really helpful isn’t information, and a prospect skims straight past it.
What works really well is case studies with facts and percentages in them. A specific number lets the reader do the maths on their own business and picture the same result happening to them. Without one, there’s nothing to picture and no problem to solve.
Go and look at your own case studies to see if they read like a thank you note rather than a result. That’s a quick fix with a real return. Here’s how we showcase our own case studies and make the important things shine.
The pricing page
Your pricing page is usually the second most visited page on the site after the homepage, and Google Analytics will confirm that for you in about thirty seconds.
Should pricing be on your website at all? We’d generally say yes.
You can showcase your pricing through price anchoring, which means putting several packages next to each other and drawing the eye to the one you want chosen. Tiering means using the number of packages to shape behaviour, and when we added a fourth tier to our own pricing, it pushed more buyers into the middle two.
You can see how we structure ours on the Rocket SaaS prices page, including how the four tiers sit next to each other.
The most common miss is listing what’s in each package without ever saying who it’s for. A single line above the boxes, or a short customer video, does more than another row of ticks.
We rebuilt our own pricing page by screenshotting the old one, throwing it into a Claude Design project and asking it simply to improve it. We were stunned by the results, and you can run this same test yourself.
Mobile
You spend all your time working on your desktop, and so does your dev team. So often everyone forgets about the mobile version of your website, and that is a big mistake.
Many B2B SaaS businesses find a significant share of their prospects browse on a phone, and your own Google Analytics will give you the exact split. Go and check it rather than assuming.
For the mobile version you’ll normally need to do a bit of restructuring, cut down big paragraphs and make the navigation easy enough for someone to have a good experience when they land. The fixes are mostly about subtraction. Cut paragraphs, cut whole sections that don’t earn their place on a small screen, and shorten what’s left. Avoid static images with text in them, because they become unreadable at phone size.
Industry and use case pages
A dropdown in your navigation with a page for each industry you sell into, each job title you sell to, or each use case you solve.
The real payoff is on paid. When you’re driving a narrow audience from LinkedIn ads, you want them landing on a page written in their language rather than a homepage that talks to everyone at once. We build these before a client’s campaigns go live, because sending expensive traffic to a general page wastes most of the budget unnecessarily.
The book a demo page
Here’s the common failure. Someone clicks book a demo and lands on a page, or a pop-up, that’s nothing but a form.
Clicking that button doesn’t mean they’ve decided. They still need convincing, and this page is your last chance to do it.
So your book a demo page should cover what the demo includes in bullets, what the visitor walks away with, who they’ll be speaking to and a photo of that person, plus a short piece of social proof.
Ideally a testimonial about the demo being worth someone’s time rather than about the product itself.
Check out our book a demo page to see how we do it here at Rocket SaaS.
The 7 out of 10 rule
We have a policy on this. If a new client’s website doesn’t score at least 7 out of 10 on conversion, we won’t switch their ads on. The site gets fixed first.
Paid traffic arriving at a site that doesn’t convert is budget filling a leaky bucket, and the bigger the budget, the faster it drains.
If you want your site scored and fixed, that’s our website conversion rate optimisation service. If it’s already good and you’re ready to turn the traffic on, that’s LinkedIn Ads.
Three things to do this week
None of these cost anything.
- Open Google Analytics and check whether your ideal customer is landing on the site, and what your mobile split looks like.
- Read your own headings from top to bottom and see whether they tell a story.
- Rewrite your hero headline in ten words or less.
That’s enough to tell you whether you’ve got a website problem or a traffic problem, and it costs you an afternoon.

Frequently asked questions
Website conversion rate is conversions divided by sessions over the same period, times 100. If 2,000 people visited last month and 40 of them booked a demo, that’s 2%. Track it per page and per traffic source rather than just site-wide.
Decide what counts as a conversion first, then keep it stable. A single site-wide number hides which page is losing people.
Map every existing URL to its new equivalent and set 301 redirects before launch. Keep the titles and headings on your highest-traffic pages, and don’t delete copy that already ranks. Crawl the old site first, so you have a full inventory of URLs to work from.
Traffic drops after a rebuild almost always come from unredirected URLs and thinner copy rather than from the design. Re-crawl after launch, and we can run that crawl for you if you’d rather not.
A full B2B SaaS rebuild runs four to five months and £20,000 to £30,000. Website projects also slip, because internal teams deprioritise them against product releases and live campaign work. Conversion work on the site you already have can start within weeks.
That gap in time to value is the whole argument for optimising first.
No, they mostly pull in the same direction. Clearer messaging and a proper heading hierarchy help readers and search engines equally. The real conflicts are narrow. Stripping copy back for a cleaner look can remove content that already ranks, and heavy animations slow the page down.
Keep the copy that earns you rankings and cut what the reader doesn’t need.
Generally yes. The pricing page is usually the second most visited page on a B2B SaaS site, and clear packaging gives a buyer who’s already considering you a reason to move. If your deals are bespoke, publish a starting price and an enquiry route rather than nothing at all.
Hiding your pricing doesn’t remove the question. It just moves it to a sales call the buyer may never book.
Start at the bottom of the funnel, with the pages a ready buyer lands on first. Fix your messaging first, then your hero section, then your headings, your product visuals and your demo page. Those changes affect every visitor from the day they go live.
Leave A/B testing until later. On a B2B site the biggest wins are usually obvious enough that you make the change and watch what happens, and most sites don’t have the traffic for a test to tell you anything reliable.
