Why did my Google rankings drop, and how do I find the cause?

First, find the date and the shape

Search Console’s Performance report, compared against the previous period, shows the day the line broke. That date is the most useful fact you will get, because almost every cause has a date of its own to match it against. Then the shape:

• One page fell. Something happened to that page — it was edited, redirected, deleted, or a competitor built a better one.
• A group fell — all the city pages, all the blog posts. A template or a section changed, or an update re-weighted that kind of page.
• Everything fell at once. A sitewide cause: a technical block, a profile suspension, a core update, or a migration gone wrong.
• Impressions fell but position held. Fewer people are searching — seasonality, or Google showing an AI answer where the links used to be.
• Impressions held but clicks fell. You are still shown; something above you is taking the click — an AI Overview, a new competitor’s ad, a lost map-pack slot.

Cause one: the site changed

The most common cause, and the one owners overlook because nobody told them. A redesign that changed every URL without redirects. A developer’s noindex tag left on after a staging site went live. A plugin update that broke the page. A certificate that expired and turned every visit into a warning screen. A page deleted because it “looked old” that had been bringing half the calls. A new theme that doubled the load time.

Ask whoever touches the site what happened in the week before the date. Then verify: site:yourdomain.com for indexing, the page source for a noindex, /robots.txt for a block, PageSpeed Insights for speed, and the old URLs for redirects. Most drops end here, and most are fixed in an afternoon.

Cause two: the Business Profile changed

If the drop is in map-pack visibility — calls fell but the site’s organic positions did not — look at the profile. A suspension removes it entirely, often after an edit Google’s systems read as suspicious (a name change, an address change, a category swap). A wave of reviews removed drops prominence overnight. A competitor reporting your listing, a duplicate listing appearing, or hours marked closed by a “suggested edit” all happen. The profile’s own dashboard shows suspensions; the review count on the listing shows the rest.

Cause three: Google changed

Google runs core updates several times a year and announces them on its search status dashboard, with start and end dates. If your drop is sitewide, began on or just after an update started, and nothing changed on your side, the update re-weighted something Google rewards — typically toward pages that show real experience and answer the question, and away from thin, generic or copied content. There is no “recovery” beyond making the site genuinely better, and the improvement usually registers at the next update rather than the next crawl.

A related, newer shape: positions held, clicks fell, because Google now shows an AI Overview above the results for that search. That is not a drop in ranking; it is a change in what a ranking is worth, and the answer to it is the AI Overviews work — being the business the answer names.

Cause four: a competitor got better

Search the phrases that fell, from a location where the customers are, and look at who is above you now. If it is a business with a new site, a page for exactly that service, and a review count that has doubled, nothing happened to you — something happened to them. The fix is the same work, done better: the page, the reviews, the profile, the listings. It is the least dramatic cause and the one that gets diagnosed as a penalty most often.

The rare cause: a manual action

Search Console → Security & Manual Actions. A manual action means a person at Google found the site breaking a spam policy and the report names which. It is rare for a legitimate local business and it is the only case where the word “penalty” applies. If the report is empty, you do not have one, and the cold-calling agency offering “penalty recovery” is selling a cure for an illness you do not have — one of the red flags. The backlinks post covers the one kind of manual action a past agency can leave behind.

What to do once you know

Fix the specific cause and only that. Redirects for the changed URLs; the noindex removed; the plugin rolled back; the certificate renewed; the deleted page restored and improved; the profile reinstatement filed; the thin pages rewritten as real answers; the competitor out-worked on reviews and pages. Then wait through a re-crawl — days for a technical fix, weeks for content — before judging, and keep the date and the cause in a log, because the next drop will have one too.

What not to do: panic-buy links, change everything at once so the next drop has no diagnosis, or switch platforms because the site “stopped working.” The drop had one cause. Find it.
