Last months landing-page update was hasty, but a big improvement.
We have taken the next step - I've optimised the site for inbound links. It now scores very well on the conventional tests (95% on Lighthouse, A+ on Pingdom etc.).
The site has gone from 2 landing pages to 17, and I've got another 64 pages under "draft". Ultimately we're looking for long-tail keywords by writing about the different industries we can serve, and also giving some decent information about each of our individual features.
Tech-wise I'm using the Hugo Static-Site-Generator - I've used it for my personal blog before. It's fantastic.
