How healthchecks work

Every link you monitor is checked on a regular schedule. A healthcheck follows the link exactly like a real shopper's browser would, then records what happened.

What we look for

• Reachability — does the link resolve and load, or does it time out, hit a

DNS failure, or return a server error?

• Hard 404s — the destination page is gone.
• Soft 404s — the page loads with a 200 status but is really an

"out of stock" or "product not found" placeholder.

• Tag stripping — your affiliate tracking parameter survives the full

redirect chain. If a hop drops it, you stop getting paid even though the link "works".

• Domain drift — the link quietly ends up on a different final domain than

expected.

• Excessive redirects — long redirect chains that hurt conversion.
• Content / price drift — for product links, whether the item went out of

stock or the price changed.

Reading statuses

Each link shows its latest status:

• OK — healthy, tag intact, destination as expected.
• HARD_404 / SERVER_ERROR / DNS_FAIL / TIMEOUT — the link is broken.
• SOFT_404 / OUT_OF_STOCK — the page loads but the product is unavailable.
• TAG_STRIPPED — the link works but your affiliate tag was dropped.
• DOMAIN_DRIFT / EXCESSIVE_REDIRECTS / CONTENT_DRIFT — the link behaves

differently than it should.

How often we check

Check frequency depends on your plan. Higher tiers check more often, so you find out about breakages sooner. See Billing & plans for details.
