Optimisation How to optimize the conversion rate of a B2B website: complete guide 2026

In between sits a visitor deciding alone, with nobody there to answer their questions.
The all-in-one platform that simplifies everything, a dashboard screenshot, a row of logos. The prospect comparing three tools in one afternoon sees no difference and goes straight to the pricing tables.
Years of development, customers who don't churn, details your competitors don't have. Online: three screenshots and a feature list where everything looks the same.
No journey, no moment where the next step is offered. Your analytics will show you the visit. It will never show you the trial you just lost.
Paid campaigns, outbound, bids climbing every quarter. You rent your pipeline by the month. The day the budget drops, signups stop the next morning.
A prospect has already formed a view of your product before creating an account.
And your pipeline stops depending on this month's ad budget.
It clicks when a visitor sees a situation described better than they could put it themselves. Your site names that problem, for a specific profile, before it talks about you. The people it doesn't concern leave, and that is the point.
Use cases played out, before and after, what changes in a working day. The prospect understands your tool without creating an account, and reaches the trial already knowing what they came to do. Activation goes up, and your support answers the same questions less often.
A recommended plan, a readable annual toggle, proof placed where doubt appears, objections handled the moment they surface. It's your most visited page: every removed friction shows up directly in signups.
A page per use case, per integration and per alternative, written for what your prospects type into Google and ask AI assistants while they are comparing. A bid stops producing the moment you stop paying for it; those pages are still there the following quarter.

Sébastien is always attentive and understood our needs perfectly when it came to redesigning our website! The new site looks great and was delivered on time. We've already gained a few customers thanks to the improved SEO of the new site

The new website much better reflects who we are. It tells our story more clearly, it's easy to navigate, it looks fresh and modern. It is more Nallian.

You don't talk to a salesperson who reports to a project manager, who briefs a developer and a designer: all those people sit in front of you, in one person, from the very first meeting.
from €595
Before a single line of code, we clarify the path from visitor to trial. The design then does the work of making your product understood in seconds.
from €1,190
I build your marketing site from scratch: it loads in under a second and turns visitors into trials and demos. Pages your marketing team can edit, and code that is 100% yours.
from €595
Your prospects search for a solution on Google and ask ChatGPT to compare three tools. I structure your site so it shows up in both places, and I send you the ranking report so you can watch it move.
from €595
Signup qualification, follow-up sequences, reporting, sales alerts: I automate what sits between your site and your product, with or without AI. Measurable results within 4 to 6 weeks.
I don't hand over a project and vanish. Updates, optimisations, A/B testing and dashboards: I stay your partner for the long run.

25 minutes to look at your situation together: where your journey loses visitors, what your pages weigh on Google today, what AI assistants say about your product when asked. You leave with a clear diagnosis, even if we never work together.
It's free, there's no commitment, and you get me directly on the phone. The developer you talk to is the one who will build your site.
Three formats depending on your stage, always at €595 per working day. Landing page (1 page, conversion funnel, PageSpeed 95+): 2 days, from €1,190. Showcase website (5 to 10 pages with SEO blog, product pages and pricing): 6 days, from €2,975. Website with CMS (10 to 25 pages, SEO/GEO silo architecture, multilingual, CRM integrations): from 12 days, from €7,140. Beyond 25 pages: custom quote. The price covers custom design, technical SEO and delivery in 1 to 10 weeks depending on the format. A monthly content management retainer is available as an option. A 25-minute call is enough to scope your needs and identify the right format.
Webflow and Framer work well for a first site. The limits show up when you want a structured conversion path, dedicated feature pages that rank on Google, advanced structured markup or a genuinely worked pricing page: performance plateaus on Core Web Vitals, the CMS stays basic, and you depend on the vendor's ecosystem. A custom site hands you back control: PageSpeed 95+, native SEO and GEO, free architecture, and code that belongs to you.
Yes. The site is built with Astro, a standard open-source framework. Your dev team can work on the code at any time: modify a page, add an integration, deploy a change. The code is hosted in your own Git repository, documented, and follows industry conventions. The goal is for your marketing team to manage content independently (via an admin interface or directly in the files) and for your dev team to step in when needed, without depending on Numinam.
The pricing page is often the most visited and the least polished. I apply a few simple principles there: the recommended plan highlighted visually, the annual / monthly toggle with the saving shown, social proof placed near the action buttons, and the FAQ built in so objections get handled where they appear rather than after the visitor has left.
I cannot promise you a number: the conversion rate depends on your product, your price and the quality of the traffic arriving. Be wary of anyone who quotes you a multiplier before seeing your pages.
What I can tell you is where visitors get lost on the SaaS sites I audit: a homepage that qualifies nobody, feature pages that describe the tool without answering objections, and a pricing page that leaves people to choose alone. During the 25-minute audit, we look at your current rate and the pages where it drops. The target gets set from there, not from a market average.
Yes, and it is often the least worked part. When a prospect searches "collaborative project management tool" or "automatic invoicing software", they are in active comparison: purchase intent is strong. A dedicated feature page, structured around that search, captures that traffic.
Those are also the pages ChatGPT, Perplexity and Google AI Overviews cite when a user asks for a recommendation.
Three options depending on your situation. I can write the content from A to Z (included in the budget or as a supplement depending on volume). I can optimise the content you provide (restructuring, SEO, conversion copywriting). Or I can work directly with your marketing team or copywriter to produce together. We define the model during the scoping call based on your internal resources.
The complete source code lives in your own Git repository from day one, on very widespread technologies (Astro, Node.js), with the technical documentation delivered at launch. Your dev team, or any other developer, can take over.
What I cannot promise is being available forever; what I can guarantee is that my leaving does not block you.
Yes. Existing content (text, images, structure) is carried over and integrated into the new architecture. If your Webflow site has SEO traffic, 301 redirects are set up on every URL to preserve your Google rankings. The Webflow site stays online throughout the development phase. The switch happens once everything is tested and validated.
