Is Your Rank Tracker Actually Tracking Accurately?

Intro

Rank tracking looks simple from the outside.

You enter a keyword. You select a location and device. Your tracker tells you where you rank.

But there is an important question most SEO teams rarely ask:

Did the rank tracker actually collect enough of the Google SERP to find your ranking?

Recent changes to Google search results have made that question much more important.

At Ranktracker, we began noticing significant changes in SERP behaviour around September 17, 2026. The situation became considerably more disruptive around Google's September spam update.

While adapting our own infrastructure, we tested more than 20 other rank tracking platforms.

What we found was concerning.

Some trackers were returning incomplete SERPs.

Others were returning a different number of results from one request to the next.

In some of our tests, trackers that were supposed to be collecting dozens of search results returned only a handful.

We even saw cases where only 1–3 results from the first page were successfully collected.

The problem is not simply that fewer results are displayed.

It can make the ranking data itself wrong.

Your Keyword May Not Have Dropped at All

Imagine one of your keywords ranks at position 38.

Yesterday, your rank tracker successfully retrieved enough of the SERP to find it.

Your dashboard reports:

Position 38

The following day, Google returns an unusual SERP or the crawler encounters a problem.

This time, the tracker only manages to retrieve the first 20 results.

What happens next depends entirely on how the tracking platform handles that failure.

A poorly designed system may report the keyword as:

• Lost
• Not ranking
• Outside the Top 50
• Outside the Top 100
• Down 60+ positions

But nothing necessarily happened to your Google ranking.

The tracker simply failed to reach position 38.

That is a very different problem.

Yet from the customer's perspective, both situations can look identical in a ranking dashboard.

Incomplete SERPs Can Create False Ranking Volatility

This becomes even more problematic when the number of results collected changes from one search to another.

Consider this pattern:

Day 1: 50 results collected Day 2: 20 results collected Day 3: 7 results collected Day 4: 50 results collected again

A keyword ranking at position 32 could appear to:

Rank → disappear → disappear → reappear.

Your SEO team might assume Google is heavily moving the page around.

In reality, the page could have remained around position 32 the entire time.

The volatility came from the rank tracker rather than Google.

That can affect far more than one keyword.

If thousands of keywords are being tracked, incomplete collection can distort:

• Visibility scores
• Position distribution
• Lost keyword reports
• Ranking movement
• Competitor analysis
• Client reports
• Historical ranking graphs
• SEO performance decisions

It can make a perfectly healthy campaign look like it has suffered a major ranking decline.

Showing Data Is Not the Same as Collecting Accurate Data

This is an important distinction.

A rank tracker can still have a beautiful dashboard.

It can still display charts.

It can still calculate movements.

It can still tell you that 500 keywords dropped yesterday.

But all of those calculations depend on the quality of the SERP data underneath them.

If the underlying crawl is incomplete, the reports built from that data can also be inaccurate.

That is why we believe the real question should not simply be:

"Does my rank tracker show my rankings?"

It should be:

"How does my rank tracker behave when Google does not return the expected SERP?"

Why Ranktracker Retries Incomplete Searches

At Ranktracker, we do not want an unsuccessful crawl to automatically become a ranking loss.

There are situations where Google does not return the expected number of search results on the first attempt.

That happens.

The important part is how the tracking system responds.

If we have historical evidence that a keyword has appeared deeper in the search results, we know that stopping after the first few results may not be enough.

So we retry.

For keywords that we have historically detected across many pages of Google results, our system continues trying to retrieve the SERP rather than immediately assuming the ranking has disappeared.

This is particularly important for our Top 100 tracking.

If we tell a customer that we track the Top 100, our infrastructure needs to make a genuine effort to retrieve that depth of data.

Why Full Top 100 Tracking Matters

Some ranking platforms have reduced their standard tracking depth.

You may see Top 20, Top 30 or Top 50 tracking offered instead.

That makes the infrastructure easier and cheaper to operate, but it also removes valuable information.

A keyword moving from position 71 to position 48 can be an important SEO signal.

So can a keyword gradually improving:

82 → 69 → 54 → 41 → 27 → 18

If you only begin tracking the keyword once it reaches the Top 20 or Top 50, you lose much of that journey.

Ranktracker continues to provide Top 100 tracking across desktop and mobile.

And we have continued doing so without introducing an additional charge simply because Google's infrastructure became harder to track.

This Isn't the First Major Google Change We've Seen

Ranktracker has been tracking search rankings since 2012.

We are not a new platform that entered the market during the recent AI boom.

During that time, Google has changed enormously.

Search result layouts have changed.

Personalisation has changed.

Local results have changed.

Mobile SERPs have changed.

Google has introduced featured snippets, knowledge panels, AI Overviews and countless other SERP features.

One of the biggest technical changes for rank tracking came when Google removed support for retrieving 100 results using num=100.

That dramatically changed the economics and technical complexity of collecting deep search results.

We adapted.

Customers continued receiving Top 100 tracking.

The recent SERP changes have been another major challenge — arguably one of the most significant changes the rank tracking industry has faced since the removal of num=100.

And once again, we adapted.

What We Found Testing More Than 20 Trackers

During our testing, we saw several recurring behaviours across different platforms.

Some successfully retrieved the expected results most of the time.

Others struggled significantly.

We observed examples of:

• Search requests returning only part of page one
• Result counts changing significantly between requests
• Crawls stopping after one or two pages
• Platforms advertising deeper tracking than the SERP data we could observe being returned
• Rankings disappearing when deeper pages could not be retrieved
• Inconsistent results between repeated searches

We are deliberately not naming individual platforms here.

The purpose is not to attack competitors.

Google changed something fundamental about how SERPs were being returned, and the entire rank tracking industry has had to react.

We experienced the problem ourselves.

The difference comes down to how each platform responds to incomplete data.

Our Recovery After the September Changes

The impact was clearly visible in our own tracking data.

Around September 17, we began seeing an increase in keywords being placed into the 101+ category.

As the disruption increased, that number rose significantly.

Once our changes were deployed, the trend began reversing.

Every day since, coverage has continued improving as more keywords are successfully retrieved at their correct ranking depth.

That recovery is particularly important to us because we did not want to simply hide the problem in the interface.

We wanted to fix the underlying SERP collection.

Today, Ranktracker is again collecting:

• Full Top 100 results
• Desktop rankings
• Mobile rankings
• Daily ranking history
• Deeper SERPs through retry logic
• More reliable position distribution data

How to Check Whether Your Rank Tracker Is Accurate

You can test this yourself.

Take several keywords that your tracker recently marked as lost or that experienced unusually large drops.

Then manually search deeper into Google or compare them using another source.

Pay particular attention to keywords that previously ranked between positions 20 and 100.

If your tracker says a keyword disappeared completely but you can still find it around its previous position, the issue may not be your website.

It may be the data collection.

Also look for strange patterns such as large groups of keywords disappearing and then reappearing the following day.

Sometimes that represents genuine SERP volatility.

Sometimes it represents an incomplete crawl.

The two should not be confused.

Rank Tracking Is Only Useful If You Can Trust the Data

SEO teams make important decisions using ranking information.

Agencies send it to clients.

Companies use it to measure campaigns.

Content teams use it to decide which pages need improvement.

Management uses it to understand organic performance.

That makes data quality more important than ever.

A rank tracker should not tell you that a keyword disappeared simply because its crawler stopped too early.

At Ranktracker, we have spent more than a decade adapting our infrastructure as Google has changed.

The latest changes have been difficult for the entire industry.

But our approach remains the same:

Collect as much accurate SERP data as possible, retry when necessary, and give customers the full Top 100 without charging them more simply because tracking became harder.

If you are unsure whether your current rank tracker is still accurately collecting your rankings, compare the data yourself.
