TL;DR: A sudden drop in rankings can be caused by a technical fault, website changes, a Google update, a security or spam issue, or stronger competition. If it’s your traffic that has fallen, changing demand or changes to the search results page could also explain it. Understanding what has dropped helps you work out which causes are worth investigating.
A sudden fall in rankings feels as though something has broken. Sometimes it has. But not always: Google’s guidance on debugging drops in search traffic says an algorithm update can move a site down when there is nothing fundamentally wrong with its content.
The cause isn’t always obvious, and the right response depends on what has changed. This guide explains the main reasons rankings can fall, as well as why traffic can drop even when positions stay much the same. For a step-by-step investigation, see our guide to diagnosing a drop in keyword rankings. If your main concern is fewer visits, our guide to why organic traffic drops looks at that in more detail.
Have Your Rankings Dropped, or Just Your Traffic?
A drop in visits doesn’t always mean you’ve lost rankings. Fewer people may be searching, or your listing may be getting fewer clicks. Before deciding which explanation fits, check whether your keyword positions, impressions or clicks have fallen.
Search Console and your rank tracker can help you tell the difference. Avoid relying on a single search for your own website, as the results you see may differ from those your customers see. Our guide to tracking your keyword positions on Google explains the tools available.
Top Tip: Don’t assume a Google update is behind the drop just because the dates match. Check whether anything changed on your website too, such as a redesign, plugin update or content edit. The Google Search Status Dashboard lists confirmed updates, but you’ll still need to look at your own site to understand what happened.
Causes on Your Site
A technical fault
A technical fault can stop Google from accessing your pages or remove them from search results altogether. This might affect the whole website or just a group of pages. One example is a noindex tag left on pages after an update. A page with a noindex rule is dropped entirely from search results once Google crawls it and sees the instruction, so the effect may appear gradually. If these terms are unfamiliar, our explanation of crawling and indexing covers the basics.
“When a client’s rankings drop suddenly, the first thing they usually ask is whether Google has had an update. Sometimes it has, but more often the cause is something that changed on their own site. In one recent case, a client’s organic traffic fell by around 70% in the week after a website redesign, and Search Console showed indexed pages dropping from 112 to 19. They assumed it was an algorithm update, but Google had confirmed no update, and the drop began the week the site launched.
The Pages report showed 93 pages excluded by a ‘noindex’ tag: the new site had gone live with the staging setting still in place. Once we removed it and resubmitted the sitemap, indexed pages were back to 108 within five weeks, and weekly clicks recovered to about 95% of their pre-redesign level within eight weeks (3,700 against 3,900, compared with the four weeks before launch). Before you blame Google, check what changed on your own site in the days before the drop.” – Eviee Taylor, Senior SEO Executive
Changes you or your developer made
If your website has recently changed, that’s worth investigating. A redesign, migration or content rewrite can affect how Google finds and understands your pages. Removing useful content, changing URLs without suitable redirects or removing internal links can affect pages that previously performed well. Some ranking fluctuations can also happen during a site move while Google recrawls and reindexes the pages. Permanent redirects from old URLs to their relevant replacements help Google and visitors reach the right content.

A security or spam problem
Google defines hacked content as content placed on a site without permission because of a security weakness, and its spam policies say sites that break them may rank lower or not appear at all. Google also says security issues can lead it to warn people before they reach your site, which can reduce search traffic. The spam policies cover things such as link spam, hidden text and mass-produced low-value pages.
If a person at Google decides pages break the rules, that is a manual action, and you are told in the Manual actions report and the Search Console message centre. Spam is also caught by automated systems, so having no message does not rule it out. A message does make the cause clear, and the fix is to correct every issue it lists and then request a review.
Causes at Google’s End
A Google update
Google makes broad core updates several times a year. Losing positions after an update doesn’t automatically mean your page has a fault. Google may be giving other pages more prominence. The Search Status Dashboard lists confirmed ranking updates with their start dates and how long each ran, so you can see whether one coincided with your drop.
To assess the effect of a core update, Google recommends waiting at least a full week after it finishes before analysing your site in Search Console, and comparing against the week before it started. For a small drop, it says there is no need for drastic action. For a large, sustained one it recommends a deeper self-assessment: look at which pages and which searches lost most, then judge those pages against the questions in its helpful content guidance.
Changes to the results page: fewer clicks without lower rankings
Your page may receive fewer clicks even if its organic position has barely changed. Ads, AI Overviews, featured snippets and other features can make your listing less prominent or give people an answer without them visiting your site.
Your title and snippet also affect how appealing your listing looks alongside other results. If clicks have fallen while impressions and positions are broadly stable, the results page is worth considering before assuming you’ve lost rankings.
Causes in Your Market
Stronger competitors and lost links
Rankings are relative. A competitor can overtake you by improving their content or earning relevant links, even if nothing has changed on your own site. Losing valuable backlinks may also affect performance: Google includes link analysis among its ranking systems. Neither a competitor’s update nor a lost link proves why your rankings fell, but both can help explain a change once obvious technical problems have been ruled out.
Changing demand and search intent
Lower demand can reduce traffic without lowering your rankings. If fewer people are searching for your products or services, you may receive fewer impressions and visits even when your positions stay broadly stable. Comparing the same period last year and looking at Google Trends can help you recognise seasonal or wider changes in interest.
A change in search intent is different. If the results now favour product pages, comparison guides or another type of content, your page may no longer match what Google considers most relevant to that query. Our guide to search intent explains the main types and how to recognise them.
“Here at Wildcat, we recently saw a drop in keyword rankings for a client in September of this year, around the time of Google’s spam update, which was our initial concern due to the timing of the ranking drops.
After reviewing the affected pages alongside Google Search Console and GA4 data, we found that changes in user behaviour were a more likely explanation than the update itself, as GA4 showed a decline in organic page views (around 25%) and key events (around 33%) in the first half of September. However, this doesn’t necessarily prove a behaviour change was responsible for the ranking drops, as GSC clicks were actually up 1.4% over the 28-day period we reviewed; we weren’t seeing the same decline across search performance. We suspected user behaviour not based on GA4/GSC data, but based on seasonality patterns observed in the past, industry insights from the client & competitor analysis.
Visibility has since recovered, so it’s a good example of why we look beyond algorithm timelines before deciding what action to take. This specific example shouldn’t have been automatically attributed to a Google update and, as we also investigated the changes across different data sources, we couldn’t establish a definite cause.” – Fiorela Imerai, SEO Account Director
Will My Rankings Come Back?
There’s no single recovery time because the causes are different. Fixing an indexing mistake is a different situation from improving content that competitors have overtaken. Google says changes to your website can take anything from a few days to several months to have an effect, and improvement isn’t guaranteed. A review after a manual action can also take several days or weeks.
Google also recommends avoiding radical changes to pages that are already performing well. Once you have identified a likely cause, prioritise the changes needed to address it and record what you changed and when. Avoid unrelated edits while you assess the result. Where several technical faults need fixing, address them together rather than leaving known problems in place simply to change one thing at a time.
