Heimdall Digital Holdings LLC
We build and look after useful websites.
Heimdall Digital Holdings is the company behind a growing set of web properties: SEO and GEO tools, free utility apps, link-in-bio and social proof tools, a URL shortener, automation services and comparison sites.
What we do
One company, many small sites
Each site has one job and tries to do it well. The holding company keeps the lights on behind all of them.
Build
We design and launch websites and tools around a specific problem, like checking a page's SEO, shortening a link or answering a phone call.
Own
Every property in the portfolio is owned by the company, so domains, hosting and accounts live in one place with one set of standards.
Operate
We handle the unglamorous parts: hosting, security updates, uptime, support email and steady improvements after launch.
Portfolio

How we work
Keeping watch
Heimdall is the watchful guardian of Norse myth, the one who sees and hears everything along the bridge. It felt like the right name for a company whose job is to keep an eye on its sites.
Useful first
A site earns its place by solving a real problem. Many of our tools are free to use.
Plain language
We explain what our products do and what they cost without hype or fine print games.
Fast and light
Pages should load quickly on an ordinary phone. We keep code lean and hosting tidy.
Looked after
We update, patch and improve the sites we own instead of launching them and walking away.
