This morning, back on the bike after a few days in Madrid. Marcel Sembat, Boulogne. Destination Opéra, Paris 9th. About forty minutes, a full east-west crossing of Paris, and a collection of red lights that gave me plenty of time to think.
Because Google algorithm updates are exactly that. Red lights. Nobody wants them. Everyone deals with them. And yet.
The red light everyone runs
On a bike ride between Boulogne and Opéra, there are two types of cyclists. Those who respect the lights, who arrive maybe thirty seconds later, but arrive. And those who run them, who save time in the short term, and who sooner or later end up in a collision or with a fine.
In SEO it’s identical. Google Core updates, Helpful Content Updates, algorithm tweaks: these are red lights. Some sites pretend not to see them. They keep publishing duplicate content, buying dodgy links, optimising for crawlers rather than humans.
It works. For a while.
And then one morning, rankings collapse. Not gradually. Overnight.
Why the red light exists
The red light isn’t trying to slow you down for fun. It regulates flow, protects other users, makes the overall journey smoother for everyone.
Google doesn’t push updates to annoy webmasters on a Monday morning either. Each update responds to an observation: low-quality sites ranking too well, mass-generated content polluting results, manipulative practices distorting relevance.
The 2023 Helpful Content Update? A giant red light planted in front of content farms. Panda in its day? Same thing for duplicate content. These updates don’t punish SEO. They punish lazy SEO.
The good cyclist knows the route
What separates the cyclist who swallows Marcel Sembat-Opéra effortlessly from the beginner who struggles is terrain knowledge. They know where the long lights are, the bottlenecks, the sections to avoid at rush hour. They anticipate, adapt their pace, don’t sprint pointlessly between two obstacles.
In SEO, that’s called staying informed. Following Google Search Central announcements, reading post-update analysis from Semrush or Sistrix, understanding what shifted and why. Not to bend the rules. To ride with the traffic, not against it.
A site that produces useful content, answers real search intent, loads fast on mobile: that one sails through updates like a green light. It doesn’t even accelerate.
And the shortcuts?
Between Boulogne and Opéra, there are tempting pavements, wrong-way streets that would save a minute, lights you run when nobody’s around.
In SEO that’s called Black Hat. Keyword stuffing, bought links, cloaking, content generated at scale with no added value. It works until the next update. Which always comes.
Google has a memory. And unlike the driver who didn’t see you cut across the pavement this morning near Pont de Saint-Cloud, the algorithm keeps records.
Opéra, green light
I made it to the office. On time. No notable infractions.
SEO is the same. Build a clean route, respect the flow rules, adapt when the signals change. And you get there. Maybe not first. But you get there, and you stay.
Shortcuts are for days when you really can’t be bothered. On a bike and in SEO, they always end up costing you.
Quick glossary for the non-geeks
Google Core Update: a major update to Google’s algorithm, released several times a year. It reassesses the relevance and quality of websites in search results. Some sites rise, others fall, sometimes dramatically.
Helpful Content Update: an update launched by Google in 2022 to penalise content written for search engines rather than humans. If your site publishes useless content at scale, this is the one that deals with it.
Black Hat SEO: a set of practices that try to manipulate Google’s algorithm by bending its rules. Effective short-term, destructive medium-term. The digital equivalent of running every red light in Paris.
Keyword Stuffing: a Black Hat technique that involves repeating a keyword excessively in a text to try to rank better. Google detects it and penalises. It read badly in 2005, it doesn’t work at all in 2025.
Crawler: a bot sent by Google to browse and index your site’s pages. It decides what Google knows about you. A well-structured, fast, clear site: it loves it. A slow, poorly coded site: it might come back later.
