Engels is a Belgian family business that makes windows and doors in wood, aluminium and PVC, sold through its own Engels stores and a project-market division.
Since early 2020, Wildstream has driven Engels’ digital lead generation, nearly doubling sales-accepted leads in one year, and rebuilt its website in 2021 without losing search performance.
In 2020 Engels received far more qualified leads than in 2019, while spending 14% less on its total budget
Organic keywords ranking in the top 10 and top 3 roughly doubled to tripled after the new website went live
Continuous A/B testing on the quote form lifted its conversion rate from 12.47% to 19.54%, raising overall CRO by 42%

A window and door manufacturer relying on showroom sales had to digitize lead generation quickly when lockdowns hit. The 2020 ambition was 20% more retail sales through digital channels: 20% more sales-accepted leads than in 2019 at a 20% lower cost per lead. Strict lead criteria, COVID showroom restrictions and coordinating 25 salespeople across 11 regions made the task harder.
In 2020 Engels received far more qualified leads than in 2019, while spending 14% less on its total budget.
Shifting budget to high-intent search and remarketing halved the cost of each sales-accepted lead compared with 2019.
Continuous A/B testing on the quote form lifted its conversion rate from 12.47% to 19.54%, raising overall CRO by 42%.
Wildstream started with an audit of CRM, sales and analytics data, competitor and keyword research, and a performance playbook with real-time dashboards in Google Data Studio. Awareness campaigns were stopped in favour of Google and Bing search; once efficiency was proven, top- and mid-funnel campaigns, lead magnets and marketing automation scaled the results.
Rules and targets for every action, tracked in real-time dashboards, create a shared feedback loop between marketing and sales.
A window checklist, an inspiration quiz and a catalogue capture prospects earlier in their search, long before a showroom visit.
Automated nurture flows turn marketing-qualified leads from social and display campaigns into sales-accepted leads for the showroom teams.
Sales-accepted leads from paid advertising grew 114%, proving that high-intent search was the right place for the budget.
SEO brought in 77% more sales-accepted leads, building a non-branded traffic source that keeps working without media spend.
Social and display campaigns generated over 1,500 marketing-qualified leads, 3% of which converted into sales-accepted leads.
Lead quality and quantity were balanced across 11 regions and 25 salespeople, so every showroom team received usable leads.
Sales and marketing now judge every campaign on the same lead data, so budget follows what actually converts.
Renewing a website risks losing hard-won search rankings. Engels’ existing site loaded slowly, performed poorly on mobile and was hard for the team to edit. The rebuild had to refresh the brand and restructure the site around search demand and the user journey, without losing the authority of the domain and key pages.
Search positions rose gradually in the first two months after launch, with a slight lift in average click-through rate.
Organic keywords ranking in the top 10 and top 3 roughly doubled to tripled after the new website went live.
The conversion rate for booking an appointment rose significantly, and brochure downloads became a new lead source.
Wildstream rebuilt the site on WordPress with a custom page builder instead of a standard plugin, so the Engels team can manage pages easily. Existing copy was optimised and enriched with keywords, new SEO content was written, and custom lead tools were added. A phased rollout with A/B tests and a redirect plan protected the site’s search authority at launch in October 2021.
Built instead of a standard plugin, it keeps pages fast and lets the Engels team edit content without developer help.
Old URLs are mapped to their new destinations, preserving the authority of the domain and of key pages after launch.
A budget calculator and style guide, managed from the admin area, help visitors plan their project and get in touch.
Lazy loading, caching, a CDN and compressed CSS, HTML and images fix the slow loading and weak mobile performance.
The launch had no negative effect on rankings, so Engels kept the organic traffic its lead generation depends on.
A new marketing-qualified lead, brochure downloads, was defined and already generates clear interest from prospective buyers.
The streamlined CMS lets the Engels team update pages themselves, without relying on agency or developer time for every change.
Organic traffic reached four times the 2019 level after the relaunch, with growth continuing through 2021 and 2022.
The new design gives Engels a high-performance, visually strong website while keeping the brand instantly recognisable.
“We asked Wildstream to ease off the gas pedal because our production department could no longer handle the sales influx.”
