There is more than one clock

First, someone needs to accept your suggestion and update a page. Then a search system may discover and process that update. A visitor could click the link before any measurable ranking movement, or the placement might never send a customer.

That is why we would not sell "results in seven days" as a general backlink promise.

Track dates you can actually observe

Record when you sent the pitch, received a reply, confirmed the edit, and first observed a referral visit. For your own pages, use Search Console to review indexing and search performance. You cannot force a different site's recrawl schedule.

Review the destination and the context

Suppose a product earns coverage in a useful comparison but visitors leave immediately. Check whether the linked page explains the promised use case and makes the next step obvious. Waiting for the authority metric to rise will not repair that mismatch.

Look at comparable periods and note other changes, such as a product launch or site migration. Avoid crediting one backlink for a movement that may have several causes.

When to follow up

Ask for a status update when an agreed article change is overdue. Do not chase a writer because Google has not shown the movement you hoped for. That part is outside their control too.
