Before changing anything, work out which of five things happened. Rebuilding on a wrong diagnosis is expensive and common.
1. Did you change the site?
Check the date of the drop against your deploy history. If they line up, this is almost certainly self-inflicted and therefore fixable.
The usual culprits: URLs changed without redirects, a theme update that removed structured data, a noindex tag shipped to production, or a robots rule blocking something it should not.
Check for a stray noindex first. It takes thirty seconds, it is embarrassingly common after a staging site goes live, and it explains total collapses that nothing else does.
2. Did you migrate?
If a replatform preceded the drop, get your old URL list and check what each one returns now. Anything 404ing that previously had traffic or links needs a redirect to the closest equivalent — not to the homepage, which Google treats as a soft 404.
3. Is it indexing or ranking?
Different problems. In Search Console, compare impressions against average position.
Impressions fell, position held — pages dropped out of the index. Look at Page Indexing for the reason.
Position fell, impressions followed — you were outranked. That is a competition or quality problem, not a technical one.
4. Was there an update?
Core updates move a lot of sites. Check whether the drop date matches a known update, and check whether competitors moved too. If the whole category shifted, the answer is not a technical fix.
5. Is it seasonal?
Compare year over year, not month over month. A lot of "drops" are the same week last year.
What to do once you know
Technical causes get fixed and recover, often within weeks. Competitive losses need content and authority work and take months. Seasonality needs nothing.
The worst outcome is rebuilding a site that had a redirect problem, because you will lose the traffic twice.
