Attentive
Attentiveness means we don't just spot the opportunities, we keep things human with the people we work with. Together towards growth.
About
The full-service agency that got tired of finding regressions in next quarter's graph.
SiteAlert is built by 2manydots, a full-service internet agency based in Tilburg, the Netherlands. For nearly twenty years we've designed websites, shipped migrations, and watched silent CMS edits, plugin auto-updates, and rogue noindex tags quietly chew through client rankings before anyone noticed.
SiteAlert is the tool we wished we'd had years ago. Daily crawls, 20+ change types, four-layer noise filtering, and a UI a non-technical marketer can actually triage. Dogfooded across 250+ of our own client sites before it reached anyone else.

What we stand for
Three habits that ended up in the product.
Ambitious
Real results matter. That takes effort from both sides, only then can we lift your work to the next level.
Creative
Our team is built of creative thinkers and doers. Solution-minded, driven to do better every day, and curious enough to learn something new every week.
What we do
The whole loop, one app
Crawl → detect → filter noise → alert. No stitched-together tools.
Daily crawl
Every page in your sitemap, crawled from the EU with Playwright, respecting robots.txt.
20+ diff types
Meta, headings, JSON-LD, links, images, HTTP status, every dimension that matters for your site.
Noise filtered out
Four layers strip away tracking params, flickery selectors, and CMS-wide repeats.
Plain-English alerts
Email + in-app inbox that a non-technical marketer can triage on their own.
Why SiteAlert
Together we know more, learn faster, and reach results sooner.
In a continuous loop of measuring and improving, you've got the best shot at online success. We listen carefully and speak in plain English. We have a pragmatic approach and explain every step. At the same time, we dive into your organization and market so we actually understand what's at stake.
- Crawls from the outside, no tag install, no JS snippet
- Four-layer noise filter so real changes aren't buried
- Template grouping: one CMS edit = one alert, not 500
- Visual pixel diff with numbered regions for marketers
- Uptime monitoring in the same inbox as content alerts
- Hosted entirely in the EU, Supabase + DigitalOcean Frankfurt
Our friend team
A team you'd actually want to work with.
Strategists, designers, developers, and marketers, every step of what we do is in-house. That means tighter communication, shorter deadlines, and one team that builds SiteAlert, eats lunch at the same table, and answers the support ticket you'll send next week.
