Webvert was a French website “decarbonization” and web optimization service provider. It was not positioned as a traditional SEO tool; instead, it aimed to improve loading speed, reduce energy use and CO2-equivalent emissions, and indirectly improve Google SEO by cutting unnecessary bandwidth usage on content-heavy websites. The crawled text clearly indicates that the service has ceased operations and can no longer be contacted, so it is better treated as a methodological reference than as a service you can currently purchase.
Its target customers were mainly content-based websites such as corporate sites, blogs, e-commerce stores, and media platforms. Optimization areas included browser caching and HTTP compression settings, image and video dimensions/formats, unoptimized images, and uncompressed CSS and JavaScript. The service process was relatively clear: first, a full-site analysis and free report; then a fixed quote; optimization implementation within 1 to 5 days; and finally an intervention report with details, recommendations, and RSE data.
For measurement, Webvert publicly stated that it used the Green Web Foundation’s Sustainable Web Design Model v4, along with Europe’s 2022 average electricity carbon intensity of 277g CO2e/kWh. Its A–G energy-efficiency rating was built from a 2021 sample of 449 websites and changes in PageSpeed/Lighthouse scores. This level of transparency was a strength, but the measurement still mainly focused on wasted bandwidth and should not be considered a full carbon audit.
The site showed a pricing range of €200 to €5,000, with both one-off decarbonization and monthly subscription models. The free component was only an analysis report, not a free trial. The biggest issue is that the website states the business has shut down, meaning it is no longer possible to contact or purchase the service; as a result, its support score is low.
Its strengths were clear positioning, combining performance, SEO, and digital responsibility, and an emphasis on reducing page weight without changing the page’s visual presentation. Customer feedback mentioned faster loading and better Google rankings. The drawbacks are that it is currently unavailable, and details on packages, platform integrations, payment methods, and after-sales support channels are missing. It also did not clearly disclose support for systems such as WordPress or Shopify.
If it were still operating, Webvert would suit marketing or communications teams with a substantial content base, heavy pages, and a focus on SEO and ESG/RSE messaging. There is no information about access from China, payment support, or Chinese-language support. Domestic Chinese teams are advised to prioritize alternative tools such as PageSpeed Insights, Lighthouse, GTmetrix, WebPageTest, and EcoIndex, combined with front-end performance optimization services for implementation.
