Google makes thousands of changes to its search algorithm every year, averaging somewhere between nine and twenty adjustments per day, but only a handful of those are named core updates that produce noticeable ranking shifts. Google typically confirms three to four broad core updates annually, along with periodic spam updates and occasional system-specific changes.
Those two numbers describe completely different things, and confusing them is why business owners panic about the wrong events. The daily changes are refinements you will never detect. The core updates are the ones that can move your traffic 40% in either direction over a two-week window.
There is also a third category worth naming upfront: traffic drops that get blamed on algorithm updates and have nothing to do with Google at all. In my experience, that category is larger than most people would guess, and diagnosing it correctly saves an enormous amount of wasted effort.

The Difference Between Continuous and Core
Google’s search system is not a single algorithm. It is a stack of many systems working together, and different teams adjust different pieces constantly.
Most of those adjustments are invisible. A minor improvement to how one language is parsed. A tweak to spam detection in a specific vertical. A refinement to how a particular SERP feature triggers. If you rank third for your main keyword, you will still rank third tomorrow.
Core updates are different. These are broad reassessments of how Google evaluates content quality and relevance across the entire index. They roll out over one to three weeks, they get announced publicly, and they produce visible movement. Sites that gain and sites that lose both tend to notice.
Spam updates are narrower. They target specific manipulation tactics, meaning link schemes, scaled content abuse, expired domain abuse, and similar patterns. If you are operating legitimately, these usually pass without incident. If your traffic drops during a spam update, that is worth an honest audit of your backlink profile and content practices.
What Updates Have Consistently Rewarded
Here is something the update-tracking coverage tends to obscure. Despite the volume of changes, the direction has been remarkably stable for a decade.
Every meaningful update has pushed toward the same set of preferences. Content that satisfies what the searcher actually wanted. Sites that demonstrate genuine credibility. Pages that provide original value rather than restating what already exists. Experiences that work quickly and cleanly on mobile.
The tactics that get penalized have also been consistent. Thin content produced at scale. Keyword manipulation. Manufactured links. Pages built for algorithms rather than people.
This consistency is the practical takeaway. You cannot predict what the next core update will emphasize, but you can predict the general direction, because it has not changed. Sites built around the most important Google ranking factors tend to gain during updates rather than lose, and they do so without anyone having to react to anything.
The 2022 addition of Experience to Google’s quality framework fits this pattern exactly. It formalized something the algorithm had been drifting toward for years, which is a preference for content from people who have actually done the thing. If you had been building the credibility signals covered in our guide to E-E-A-T, that update was a tailwind.
Before You Blame an Update
This section is the one worth bookmarking, because most traffic drops attributed to algorithm updates turn out to be something else entirely.
When traffic falls, work through these in order before concluding Google changed something.
Check whether an update was actually running. Google announces core updates on its Search Status Dashboard and its Search Central account. If your traffic dropped on a Tuesday and no update was rolling out, look elsewhere. This takes two minutes and eliminates a surprising percentage of false alarms.
Rule out tracking problems. A broken Analytics tag, a duplicate tag firing, a consent banner change, or a migration that dropped the tracking code will all produce a traffic cliff that exists only in your reporting. Compare Analytics against Search Console clicks. If Search Console shows normal traffic and Analytics shows a collapse, your data is broken, not your rankings.
Check for technical breakage. A deployment that introduced a noindex tag, a robots.txt change, an expired SSL certificate, a server outage, or a redirect that went wrong can devastate traffic within days. Run the URL Inspection tool on your top pages. Confirm your money pages are still indexed. Problems with how Google crawls and indexes your site look identical to an algorithm penalty from the traffic graph alone, and they are far more common.
Checking those one page at a time is slow, and the point of this step is to rule the category out quickly. A crawl from Seobility flags noindex tags, redirect chains, broken links, and pages that have dropped out of reach in a single pass, which turns a morning of manual inspection into a report you can scan in a few minutes. If it comes back clean, you have eliminated the most common non-algorithm explanation and can move down the list with more confidence.
Account for seasonality. This one catches Florida businesses constantly. HVAC searches in Tampa Bay do not behave the same in October as they do in July. Roofing spikes after storms. Tax services collapse in May. Compare year over year rather than month over month, or you will misread a normal seasonal pattern as a penalty.
Look at the SERP itself. Google frequently changes what appears on a results page without changing rankings at all. If an AI summary now occupies the top of the page, or a Map Pack was added, or a competitor started running ads, your position can be unchanged while your clicks fall significantly. Search your keywords and look at what the page actually looks like now.
Check what competitors did. Someone publishing a genuinely better resource, launching a targeted campaign, or fixing a long-standing technical problem can push you down without any algorithm change. Rankings are relative.
Only after all six come back clean is an algorithm update the likely explanation.
What to Do During a Rollout
The instinct is to start changing things immediately. That instinct is wrong, and acting on it usually makes recovery harder.
Core updates roll out over one to three weeks, and rankings fluctuate throughout that window. Traffic can drop in week one and recover in week two without you touching anything. Making rapid changes during the rollout means you will have no idea what caused the eventual outcome, and you may have introduced problems that persist after the volatility settles.
Wait for the rollout to complete. Google announces the finish. Then compare your post-update numbers to your pre-update baseline over a comparable period, not to the chaotic middle.
If you did lose ground, analyze at the page level rather than the site level. Which specific URLs lost impressions and clicks? Do they share a pattern? Thin content, outdated information, mismatched intent, weak credibility signals, and pages that duplicate each other are the usual suspects. A site-wide panic response is almost never the right answer when three pages caused the problem.
The Recovery Reality
This part gets soft-pedaled elsewhere, so here it is directly.
Recovery from a core update is not fast, and it is not guaranteed. Google has been explicit that sites affected by a core update often will not see recovery until a subsequent core update processes, which can mean waiting three to six months even after you fix the underlying issues.
That timeline compounds the general patience SEO requires, which we cover in our breakdown of how long SEO takes to work. The businesses that handle this well are the ones that treated the fundamentals seriously before anything went wrong, because they have less to fix and more buffer to absorb the hit.
There is no reconsideration request for core updates. That process exists only for manual penalties, which are a separate mechanism and come with a notification in Search Console. If you have no manual action notice, you have an algorithmic assessment, and the only path forward is genuine improvement plus time.
Why Conversion Rate Is Your Best Insurance
Here is the angle nobody applies to this topic, and it changes how you should think about volatility.
You cannot control Google’s algorithm. You can control what happens to the traffic you have. That asymmetry makes your conversion rate the most reliable protection available against ranking turbulence.
Run the math. A business gets 2,000 organic visits a month converting at 1.5%, producing 30 leads. A core update costs them 35% of their traffic, dropping them to 1,300 visits and 19 leads. That is a painful quarter.
Now take the same business having done conversion work first, converting at 4%. The same 2,000 visits produced 80 leads. After the same 35% loss, 1,300 visits still produce 52 leads, which is well above where the first business started before anything went wrong.
Identical traffic, identical update, completely different business outcome. The conversion work did not prevent the ranking loss. It made the ranking loss survivable.
This is why I push conversion optimization early in every engagement rather than treating it as a later phase. Ranking gains are real but they are borrowed; Google can adjust them at any time without warning. Conversion improvements are owned. They persist through every update, they compound with every visitor you earn afterward, and they are the reason some businesses absorb a bad update while their competitors panic.
There is a defensive ranking benefit too. Pages that satisfy searchers tend to weather quality-focused updates better, because satisfying searchers is precisely what those updates are measuring. Building pages that match intent and convert well, as covered in our guide to search intent, aligns you with the direction updates consistently move.
Should You Track Every Update?
For most businesses, no. Following algorithm update coverage closely tends to produce anxiety rather than action, and much of the commentary published within days of a rollout is speculation.
A reasonable middle ground: keep an eye on Google’s Search Status Dashboard so you know when something is running, watch your own Search Console data monthly, and pay attention when your numbers move meaningfully. Skip the daily volatility trackers unless SEO is your full-time job.
What deserves your attention instead is the steady work. Publishing content that answers real questions with real expertise. Keeping the site technically clean. Earning legitimate links. Improving how well your pages convert. That work compounds regardless of what Google ships next month.
The Bottom Line
Google changes its algorithm thousands of times a year, but only three to four confirmed core updates annually produce the kind of movement worth reacting to. Spam updates target manipulation. Everything else is invisible refinement.
Before attributing a traffic drop to an update, rule out tracking errors, technical breakage, seasonality, SERP layout changes, and competitor activity. Those explain more drops than algorithm changes do.
The direction of updates has been consistent for years, which means the defense is consistent too. Build genuinely useful content, prove your credibility, keep the technical foundation solid, and optimize what happens after someone lands on your page. That last piece is the one Google cannot take away from you, and in a market like Tampa Bay where competition keeps intensifying, it is often what separates the businesses that survive a rough update from the ones that spend six months recovering.
