I Processed 2 Million Search Queries to See How Search Results Change Over Time

All SEOs talk about rankings and their volatility.
But few discuss how frequently these search results change.
That’s why I wanted to see for myself.
For several months, I studied over two million queries, analysing how results change over time. What did I want to learn? To discover some unique patterns in Google search results that not many people would pay attention to.
The conclusions I drew were revolutionary for my perception of keywords, rankings, and SEO.
The biggest revelation for me?
A large portion of search results is much less volatile than marketers expect.

Why I Decided to Analyze 2 Million Search Queries

Search ranking positions usually tend to be perceived as something permanent.
The page is ranked today; it will be ranked tomorrow.
This way of thinking leads to flawed conclusions.
Each day, Google handles billions of searches. As Google claims, over 15% of searches each day are absolutely new searches.
This means the search patterns are continuously evolving.
If the search pattern changes, it only makes sense for search ranking to change.
I did not want to base my conclusions on any assumptions. I needed real data.
For this reason, I developed a data set with over 2 million search queries from sectors like SaaS, e-commerce, finance, healthcare, local, technology, and education.
Next, I proceeded with tracking search ranking changes.

The First Discovery: Most Rankings Are More Volatile Than People Think

There is much greater volatility in search results than any SEO tool displays.
When one ranks a site only once per week, a great deal of volatility goes unnoticed.

One keyword may be considered stable when checked on both Monday and Friday.
However, during that time, that keyword may have seen dozens of rank changes.
Many first-page results across the data set would move their ranks consistently.
Certain sectors saw more volatility than others. Tech-related keywords tended to change often. Newsworthy topics changed even more rapidly. Local rankings showed constant movement in competitive markets.

The answer was clear.
Ranking alone does not tell the whole story.

Google Rewrites Search Intent More Often Than Most People Realize

Google is not the only thing ranking web pages.
Google always changes its mind about what users want.
This became one of the most dominant trends in the dataset.
A term that was showing blog posts back in January would be showing product posts by March.

While a search query that would return tutorials at first would later return comparison content.
The actual keyword wouldn’t have changed anything.
Only the intent behind the keyword was changing.
That’s why even websites that haven’t undergone any substantial change will see their ranking decrease.
There’s nothing to do with improved competition here.

It’s just Google realising that users want another kind of information.

Featured Snippets Appear and Disappear Constantly

Featured snippets seem to be a permanent feature when seen from outside.

However, what the data revealed was quite different.
Many featured snippets disappeared for some time and then resurfaced.
Several snippets had also switched hands multiple times.
Certain keywords completely lost their snippets.
This trend continued throughout thousands of informational queries.
In a study conducted by Semrush, it was seen that featured snippets affect the CTR in a big way. According to my findings, snippets tend to switch hands regularly.
For websites that have a high snippet-dependent organic traffic flow, this poses yet another problem.

While ranking on position one is one problem, retaining visibility in search features is another.

The Top Three Results Capture More Stability Than Lower Positions

A correlation was found between how high the page ranking was and its tendency toward stability.
It seemed to be consistent throughout.
Pages 8 to 10 experienced lots of change.
Pages 4 to 7 displayed moderate change.
The top three pages were most resistant to change.
Of course, this does not imply that top pages never change.
They certainly do.
However, Google seems to require better signals to shift the ranks of those pages.
SEO campaigns tend to target page one.
It would seem that the actual target should be the top three.

Search Features Are Taking More Real Estate Every Year

Organic results have taken up less real estate on screen compared to their past.
In countless searches, I've seen the increase in the number of SERP features.
Snippets.
People Also Ask.
Local pack.
Shopping features.
Video carousel.
Image pack.
Knowledge panel.
Each of these takes away from organic listings.
As reported by SparkToro, zero-click searches constitute a considerable chunk of Google searches.
What does this mean?
Rank #1 is still great.
But ranking organically in more than one SERP feature will be vital.

Some industries change dramatically faster than others.

Keywords don’t all perform in the same way.
The finance and tech sectors had some of the most volatile keywords within the sample set.
Healthcare keywords tended to exhibit a high preference for authorship.
Local business searches were quite dynamic based on geographic and behavioural information.
Educational keyword ranks were usually fairly stable.
This is important because SEO advice always tends to assume that all niches are alike.
Yet the results proved this wrong.
SEO strategies that worked well in one industry did not necessarily transfer to another.
Understanding industry nuances was essential.

The Most Unexpected Finding Wasn't About Rankings

And it wasn’t the volatility of rankings that mattered.
It was the freshness of the content.
While some websites maintained their ranking over many years,
Others disappeared rather quickly.
And it wasn’t due to backlinking and domain authority alone.
Many times, those who got to the top would just keep improving their content.
They kept updating information.
Provided new examples.
Expanded their horizons.
Answered more queries.
The winners never considered their content to be complete.

What 2 Million Search Queries Taught Me About SEO

Algorithmic SEO is a common theme in SEO conversations.
The statistics told a different story.
Google’s search algorithm keeps evolving for users.
Search intent evolves.
Search features evolve.
Your competitors evolve.
Users themselves evolve.
Sites that evolve in tandem tend to thrive.
Analysing 2 million search queries didn’t provide any clues about mysterious ranking signals.
They provided something even more valuable.
Search results are evolving targets.
The quicker you grasp how, the better off you’ll be.

Expert Perspective

"The goal of Google is to organize the world's information and make it universally accessible and useful."
Larry Page, Co-Founder of Google
This statement seems straightforward.
However, based on an analysis of millions of search results, this statement explains many things that take place behind the scenes with the help of the Google Search API.
Google does not optimise for websites.
Google optimises for users.
Sites that cater to the needs of users stand to do better than sites optimized merely for keyword optimization.

FAQ

2. Are first-page rankings consistent?
   Yes, some first-page rankings are consistent for a long time, while others are never consistent. The lower rankings are not as consistent as the top three rankings.

3. Why do Google rankings fluctuate?
   This happens due to an algorithm update, changes in search intent, emergence of new competitors, content updates, backlinking, change in user behaviour, and search engine result page features update.

4. Why do Google rankings fall when my site hasn’t changed at all?
   Because the search engine may be changing the interpretation of user intent, adding a new search function or recognising more suitable content for that query.

5. What is the most important SEO lesson we can learn by looking at millions of search queries?
   That search results keep changing, and long-term success requires adaptation to new search behavior trends.
