It's one of the most honest questions a business owner can ask an SEO provider: if I stop paying you, what happens to my rankings? The answer you'll often get is a scary one, and it's usually wrong in both directions. Your rankings don't fall off a cliff the day the invoice stops. They don't stay put forever either.
I won't give you a timeline, because nobody can source one: it depends on your competitors, your industry, and how much the search results you appear in are changing. What I can give you is what decays, what doesn't, and why.
What doesn't disappear when you stop
Good one-time work keeps working. If your provider did any of these, you keep the benefit after you cancel:
Fixing technical problems: broken pages, slow templates, pages Google couldn't index.
Rewriting page titles and descriptions to match what customers actually search for.
Building proper pages for your real services and service areas.
Setting up and verifying your Google Business Profile with the right categories.
Earning genuine links and mentions from other sites in your community.
A published page holds its place until something displaces it. Nothing in Google's systems reads your cancelled contract.
What decays, and why
What erodes rankings after you stop isn't Google punishing you. It's everyone else continuing to move.
Competitors keep publishing. If the business down the road keeps adding useful pages and earning reviews, its pages can overtake yours on the searches you both want, without yours getting any worse.
Content goes stale. Prices, hours, rules and services change. Google uses systems designed to show fresher content for searches where freshness is expected (sourced from Google Search Central), so a page that's quietly out of date can lose ground on exactly those searches.
Your Google Business Profile goes quiet. No new photos, no review replies, hours that are wrong over the holidays. I've written about what happens to a profile nobody touches, and it's often the first place a lapse shows.
Small technical problems pile up. A plugin updates, a page gets deleted without a redirect, someone uploads photos the size of a billboard. Each one is minor. Left unchecked for a year, they add up.
Which part of your retainer was actually doing the work?
This is the useful question hiding inside the scary one. Look at what you've been paying for each month and sort it into two piles.
One-time work dressed up as ongoing. If the same audit arrives every month with nothing new in it, that isn't maintenance. It's padding.
Genuinely ongoing work. New content, profile updates, review responses, and watching for and fixing what breaks. This is the part that stops when you stop paying.
If the second pile is thin, cancelling may cost you very little. If it's substantial, the question is whether you can do it yourself, and plenty of businesses can: a fifteen-minute monthly SEO routine covers the basics for a lot of local businesses.
If that doesn't fit your week, that's when ongoing help earns its fee. When it's worth paying for, what that work actually involves is written out, so you can compare it with what you've been getting.
Before you cancel, take what's yours
Whatever you decide, make sure you leave with:
Owner access, in your own name, to your Google Business Profile, Search Console and analytics.
A list of what was done, and when.
Any content, images and reports you paid for.
The logins for your website and domain, if your provider holds them.
Then keep an eye on the Performance report in Search Console over the following months. If clicks on the searches that matter start drifting down, you'll see it early and can decide whether to act. No one can promise how your rankings will move, in either direction, but you'll be looking at real numbers rather than guessing.
So which pile is bigger in your current retainer: the work that lasts, or the work that has to keep happening?
