Diagnostics
Rankings fall. It happens to well-built sites and badly-built ones, to businesses doing everything right and businesses cutting corners. What separates a two-week dip from a six-month decline is almost never how fast you react — it is whether you correctly identify which of four things actually happened before you change anything.
This guide is the diagnostic sequence we run when a business comes to us mid-drop. You can follow it yourself with nothing but Google Search Console.
- Confirm the drop in Search Console first. Rank trackers report one sampled position and are wrong often enough to cause panic over nothing.
- There are only four real causes: an algorithm update, a technical fault, a manual action, or competitor movement.
- Check for a manual action first. It takes thirty seconds and changes everything about what you do next.
- Sitewide and gradual points to an algorithm update. Sudden and page-specific points to a technical fault.
- Do not rewrite content or disavow links before you know the cause. That adds variables while the original one is still unknown.
First: Confirm the Drop Is Real
Before anything else, establish that rankings actually fell. A surprising share of the “emergencies” we get called into turn out to be measurement artefacts.
Rank trackers check a keyword from one location, at one moment, usually logged out. Google serves results shaped by the searcher’s location, device, history and whichever SERP features it decided to show that day. A local pack appearing above the organic results can push you from position 3 to a visually lower spot without your ranking changing at all.
Open Google Search Console, go to Performance → Search results, and set the date range to compare the last 28 days against the previous 28 days. Look at two numbers: average position and impressions, filtered to the queries you actually care about.
If Search Console shows no meaningful change, there is no drop. Close the tab and go back to work.
The Four Things That Cause a Ranking Drop
Almost every genuine drop resolves to one of these. They are not equally likely, and they do not look the same.
1. An algorithm update
Google changed how it evaluates pages. The signature is sitewide, gradual over one to three weeks, affecting many pages at once, and it correlates with a dated core update. Your site did not change; the standard did.
2. A technical fault
Something on your site broke. The signature is sudden and specific — a sharp cliff on a particular date, often confined to certain pages or templates, usually with a matching fall in indexed pages. Redesigns, migrations and plugin updates are the usual triggers.
3. A manual action
A human reviewer at Google penalised your site, typically for unnatural links or thin content. The signature is severe and abrupt, and unlike the others it is explicitly reported to you in Search Console.
4. Competitor movement or seasonality
You did not fall; someone else rose, or demand shifted. The signature is position roughly stable while impressions or clicks fall, or a pattern that repeats at the same point each year.
How to Tell Them Apart in Search Console
This is the part most guides skip. Four checks, in this order, will identify the cause in under fifteen minutes.
| Check | Where in Search Console | What it rules in or out |
|---|---|---|
| Manual action | Security & Manual Actions → Manual actions | Do this first. If there is a notice here, stop diagnosing — you need a reconsideration request, not an SEO tweak. If it says “No issues detected”, rule out cause 3 entirely. |
| Shape of the fall | Performance → date comparison, full site | A cliff on one date points to a technical fault. A slope over one to three weeks points to an algorithm update. |
| Sitewide or page-specific | Performance → Pages tab, compare mode | If most URLs fell together, it is an update. If a handful of pages or one template fell, it is technical — and you now know exactly where to look. |
| Indexation | Indexing → Pages | A fall in indexed pages alongside the ranking drop is close to conclusive for a technical fault: noindex tags, robots.txt changes, broken canonicals or a redirect chain from a redesign. |
| Position vs impressions | Performance → Queries tab | If average position held but impressions fell, you did not drop. Demand moved or a competitor took share. That is a content and authority problem, not a recovery problem. |
Run these in order and the answer usually declares itself. The most common outcome we see in Vadodara is the second and third checks agreeing on a technical fault that nobody connected to a website change made six weeks earlier.
What to Do in Each Case
If it is an algorithm update
Do not make sweeping changes during the rollout — positions move again while an update is still deploying, and you will not be able to attribute anything. Wait for it to complete, then look honestly at the pages that lost most. Core updates generally reward depth, first-hand experience and genuine usefulness over pages assembled to rank. Recovery normally becomes visible at the next core update, not within days. Our content methodology covers what “improve the page” means in practice.
If it is a technical fault
This is the good news case, because it is fixable and the recovery is usually fast. Work backwards from the date of the cliff: what shipped that week? Check for noindex tags, a changed robots.txt, broken canonicals, missing redirects after a URL change, and Core Web Vitals regressions. Our technical SEO process sets out the full sequence, and a structured audit will surface anything the obvious checks miss.
If it is a manual action
Read the notice carefully — it states the reason and whether it applies sitewide or to specific pages. Fix the underlying issue genuinely, document what you changed, then submit a reconsideration request. Unnatural links are the most common cause; if links were bought or built at scale, they need removing or disavowing before you file. Expect weeks, not days.
If it is competitor movement
Nothing is broken, which is harder to accept than a fault. Someone published something better or earned authority you did not. The response is competitive: look at what now outranks you, identify what it covers that you do not, and close that gap through off-page authority and depth rather than technical fixes.
When It Is Your Agency’s Fault
Sometimes the drop traces back to the people you hired — a redesign shipped without redirect mapping, bought links catching up with you, or content published at volume with no search demand behind it.
But blame is less useful than a simpler test: can they explain it? Within a day of a drop, a competent agency should be able to tell you whether it is sitewide or page-specific, whether it coincides with a known update, and whether indexation changed. Those answers take fifteen minutes in an account they should already have access to.
An agency that responds with “rankings fluctuate” and no data is the problem regardless of what caused the drop. If that sounds familiar, our 25 questions to ask before signing and our guide to SEO pricing and contract terms cover what to expect from a provider — including who should hold your Search Console access in the first place.

Frequently Asked Questions
How do I know if my ranking drop is real or just a rank tracker error?
Confirm it in Google Search Console before acting. Rank trackers report a single sampled position that ignores personalisation, the searcher’s location and SERP features. Compare the last 28 days against the previous 28 and look at average position and impressions for your target queries. If Search Console shows no change, there is no drop.
How long after a Google algorithm update do rankings recover?
Core updates roll out over one to three weeks and positions often move again during that window, so avoid large changes mid-rollout. Genuine recovery usually requires improving the pages themselves and typically becomes visible at the next core update rather than within days.
What is a manual action and how do I check for one?
A manual action is a human reviewer at Google applying a penalty, usually for unnatural links or thin content. Check Search Console under Security & Manual Actions. It takes about thirty seconds and should be your first check, because it requires a reconsideration request rather than ordinary SEO work.
Can a website redesign cause rankings to drop?
Yes, and it is one of the most common causes we see. Redesigns frequently change URLs without redirects, drop existing copy, remove internal links or accidentally publish a noindex tag. If the drop began within days of a launch, treat the redesign as the prime suspect before considering algorithm updates.
Should I change my SEO strategy immediately after a ranking drop?
No. Diagnose first. Rewriting content or disavowing links before identifying the cause usually makes recovery slower, because it adds new variables while the original one is still unknown.
Is a ranking drop my SEO agency’s fault?
Sometimes, but the more useful test is whether they can explain it. A competent agency should tell you within a day whether the drop is sitewide or page-specific, whether it coincides with a known update, and whether indexation changed. An agency that cannot answer those with data is the problem regardless of the cause.
