A Google update can take 40 percent of your organic traffic overnight. No warning. No explanation. Just a cliff edge in your analytics.
Your first instinct will be panic. Call the agency. Demand answers. Start changing things immediately.
And that's fair. You're paying them to manage this. But how your agency responds in the first few weeks tells you everything about whether they know what they're doing.
It's not about how fast they react. It's about how smart they react. Here's what a good response looks like. And what should worry you.
Start by Identifying Exactly What Hit Your Site
The first thing your agency should do is identify which Google update caused the drop. Not all updates are the same, and the type changes everything about the recovery.
Core updates. Google re-evaluates the quality and relevance of content across the web. Your site didn't necessarily do anything wrong. Google just decided someone else is now a better answer.
Helpful content updates. These target websites that publish content designed to rank rather than genuinely help people. If your site has a lot of thin or mass-produced content, this is the update that punishes it.
Spam updates. These go after deceptive tactics. Manipulative links. Keyword stuffing. Risky shortcuts.
I mention all three because I've seen agencies tell a client they were hit by a core update when it was actually a spam update caused by the agency's own link building. The diagnosis changes everything about the recovery.
Your agency should match your traffic decline to a specific update. Google publishes official announcements and rollout dates. If your agency can't do this, they're not doing the basic diagnostic work.
Nothing Changes Until the Rollout Is Complete
This is where a lot of agencies get it wrong. The traffic is dropping and they want to start making changes immediately. That's one of the worst things they can do.
Google updates take days, sometimes weeks, to fully roll out. During that window, the data is unreliable. Rankings fluctuate wildly. If your agency starts rewriting pages and changing titles in the middle of a rollout, they'll never know what caused the drop and what fixed it.
(If I'm being honest, this is where panic separates good agencies from bad ones. Good agencies hold steady and monitor. Bad agencies start throwing things at the wall.)
A good agency enforces a waiting period. They monitor Google Search Console for patterns. They track what's moving and what's stable. But they don't change anything on your site until the update has fully rolled out and the data has stabilized. That usually takes two to three weeks after Google announces the rollout is complete.
Diagnosis First. Fixes Second
Once the data has settled, your agency should run a proper diagnosis. I've seen too many agencies skip this and jump straight to "let's rewrite some content." That's guessing. Not strategy.
A proper diagnosis from your agency should answer three questions.
Which pages lost traffic? Not your whole site. Which specific pages or sections? Did the blog get hit while product pages stayed steady? This tells them whether Google is questioning your content, your authority, or your technical setup.
And this next one is something I always look for.
Which keywords dropped? Sometimes Google decides a different type of page is now the better answer. A search that used to show blog posts might now show videos or product pages. Your agency needs to identify this because the fix isn't better content. It's a different type of content.
Is it a content problem or a technical problem? These require completely different responses. Your agency should know the difference and explain it to you clearly.
They should present this diagnosis in plain language. What happened. Why it happened. What they recommend doing about it. If they can't explain it simply, they either don't understand it or they're hiding something.
The Recovery Plan. Not Guesswork
Your agency should come to you with a clear plan. Not "we'll try some things and see what happens." A structured plan with specific actions, priorities, and realistic timelines.
I've worked through this process with enough business owners to know that the best agencies follow a simple framework.
Improve. Your agency identifies pages that have potential but need work. Outdated content that needs fresh data. Pages close to ranking that need to be more helpful or thorough than the competition.
Merge. If your site has three or four thin articles covering the same topic, your agency should combine them into one comprehensive page. Multiple weak pages competing for the same keywords drag each other down.
I've seen this single step make a bigger difference than anything else in a recovery. One strong page genuinely does perform better than four mediocre ones.
Delete. Your agency should identify pages that serve no purpose, get no traffic, and add no value. Every low-quality page dilutes your overall authority. Sometimes the smartest move is to remove them.
This is especially important if your site was hit by a helpful content update. Google evaluates your site as a whole. If a significant portion of your content is unhelpful, it drags down the performance of your good pages too. Your agency should be proactive about recommending what to cut.
Content Quality Is Almost Always the Root Cause
I've seen a lot of sites get hit by updates. And in most cases, the root cause is content quality.
Not because the business owner did anything wrong. Usually because the previous agency published a lot of material designed to rank rather than designed to help. Blog posts written to hit a keyword target but offering nothing useful. AI-generated articles published without editing or expertise.
Your agency should audit every piece of content on your site. Not just the pages that lost traffic. Everything. They should identify which content is genuinely helpful and which content is pulling your site down. And they should be honest with you about what they find, even if some of the problematic content was created under their watch.
If I'm being honest, this is where you find out whether your agency has integrity. A good agency will own the problem and fix it. A bad agency will deflect and blame the algorithm.
Recovery Takes Time. And Your Agency Should Say That Upfront
Your agency should be upfront about something. Recovery is not instant.
Google typically needs to run another core update before it fully re-evaluates sites that were hit. Core updates happen roughly every three months. That means even if your agency does everything right, you might not see a significant rebound for 90 days or more.
What your agency should show you in the meantime. Steady progress on the recovery plan. Content being improved, merged, or removed. Technical issues getting fixed. Impressions stabilizing and then slowly growing. These are the leading indicators that recovery is underway.
What you should not accept. Silence. Your agency should be communicating clearly about what they're doing, why they're doing it, and what the realistic timeline looks like. If they go quiet after an update hits, that's a problem.
Red Flags in Your Agency's Response
An algorithm update is a stress test for your agency relationship. Here's what should worry you.
"Nobody knows why this happened." Your agency should know. Google publishes update announcements. The data shows what changed. If they can't diagnose the issue, they don't have the expertise.
They immediately start building links. Core updates and helpful content updates are about content quality. If link building is their first response, they're reaching for the only tool they have.
And here's one I see more often than I'd like.
They blame everything on Google. A good agency anticipated the direction Google was heading and built your site accordingly. If they're surprised by an update that rewards helpful content, they haven't been paying attention.
They make cosmetic changes and call it a recovery plan. Swapping stock images and tweaking meta titles is not a recovery. If the problem is content quality, the fix is content quality. Not window dressing.
Sound familiar?
Check Google's Status Dashboard Yourself
Your agency should tell you which update caused the drop. But here's something you can verify on your own in about two minutes.
Google publishes every algorithm update on their Search Status Dashboard. It shows the dates each update started rolling out and when it finished. You can find it by searching "Google Search Status Dashboard" in Google.
Compare the dates of your traffic drop to the dates on the dashboard. Do they line up with a confirmed update? If your agency says "it was an algorithm update" but Google shows no update during that period, the drop was caused by something else. Maybe a technical issue on your site. Maybe a competitor overtaking you. Maybe something the agency did.
Don't take their word for it when you can check it yourself in two minutes. The dashboard is public. It's free. And it gives you an independent way to verify what your agency is telling you.
Get a Second Opinion Before Approving a Recovery Plan
If your agency comes to you with a recovery plan that involves major changes to your site, pause before approving it.
I've seen agencies recommend deleting 200 pages from a website as part of an algorithm recovery. Sometimes that's the right move. Sometimes it's a drastic overcorrection that makes things worse.
Before you sign off on anything significant, a thirty-minute consultation with an independent SEO consultant can confirm whether the plan makes sense. It's a small cost compared to the risk of approving the wrong recovery strategy.
(If I'm being honest, this isn't about distrusting your agency. It's about protecting a major business asset. You'd get a second opinion before a surgery. You'd get a second opinion before a major renovation. Your website deserves the same.)
Your Monthly Reports Become Diagnostic Tools
(This is where all the documentation you've been collecting pays off in ways you might not have expected.)
Your Completed SEO Work reports show exactly what your agency did on your site over the past months. You can trace back and identify whether any of their recent changes contributed to the drop.
Your Proposed SEO Work plans show what the agency said they were going to do. If they proposed a content strategy that flooded your site with thin articles, you have documentation of that decision.
And your SEO Performance Report gives you the baseline data to measure the exact impact and hold your agency accountable for the recovery.
These aren't just accountability tools for normal months. They're your diagnostic tools when something goes wrong.
