Do4U for agencies
Agencies look after many websites at once: relaunches, translations, accessibility and search. Do4U gives you checks you can run on every client website, with findings you can work through as a list. Many of these checks run in code, without AI.
Typical duties and tasks
- Check a new client website before you start
- Find barriers and colour contrasts that are too weak
- Plan the redirects for a relaunch so that old addresses keep working
- Find broken links, redirect chains and duplicate titles
- Check the hreflang links of multilingual websites
Do4U helps you check and write. It is not legal advice: which rules apply to you, you clarify yourself or with an expert.
Tools that fit
Website check
Checks a whole page at once and gives it a score from 0 to 100; every finding leads to the right tool.
short check free, full report 5 credits per task
Accessibility check
Checks a page for common barriers and explains how to fix them.
3 credits per task
Colour contrast check
Check the contrast of your brand and website colours against WCAG 2.2 (AA and AAA), with the nearest colours that pass and an export as CSS variables. Free, in code, without AI.
free, up to 30 checks per day
Broken link check
Crawl your website and find broken links, missing images and files, redirect chains and loops. Each broken page gets a suggested redirect to export. Free, without AI.

Redirect plan
Plan the redirects for a website relaunch: match every old address to a new one, with a reason and a certainty level, and export the rules as .htaccess, nginx or CSV. The code does the checking; the AI only helps with pages that stay unclear.
usually 1–3 credits
Duplicate content check
Find duplicate and missing titles, descriptions and H1 headings, thin and near-duplicate pages, canonical and noindex problems across your website. Free, without AI.
free, without sign-up
hreflang check
Check the hreflang links of a page: return links, language and region codes, x-default, duplicates, and whether every language version is reachable, indexable and has the right canonical and html lang. Free, without AI.

Questions and answers
Which checks run without AI?
The colour contrast check, the broken link check, the duplicate content check and the hreflang check run in code, without AI.
How do I plan the redirects for a relaunch?
Paste the old and the new addresses into the redirect plan. The code matches every old address to a new one, with a reason and a certainty level. You export the rules as .htaccess, nginx or CSV.
Can I connect Do4U to my own systems?
Many tools can also be used through the REST API with an API key. The API documentation shows the fields and examples.
