While there are some reasonable assumptions of how Search Generative Experience (SGE) might affect our sites, others are not so realistic.
This article highlights:
SGE will undoubtedly impact organic search, with both positive and negative consequences, if it launches as it currently stands.
But how big will that impact be?
It is reasonable to assume that we could see a decrease in organic traffic of up to 30% – similar to how featured snippets impact some search results. This depends on the niche, business model and keyword types.
With that said, there is no magic number that can be generalized.
If there is no AI overview for the query, the impact will be close to zero.
If users are prompted to create an AI overview, a certain portion will follow through and create one.
However, creating this overview takes time, and general users won’t immediately adopt this behavior.
If your site gets an auto-generated AI overview but doesn’t appear in the response, expect a negative impact on your traffic. If you do appear, the impact will be less severe.
However, the human eye focuses more on things that appear on the left side, at least in countries where people read from left to right. So, the left part of the overview is probably more important.
Currently, sources are displayed on the right side, and there are small dropdown arrows in the response itself to signal interaction, which also reveals sources used for the response.
As such, regular organic results will be pushed down just like if any other SERP feature (i.e., ads) appears above them.
It’s fair to say that Google has less pressure to release the SGE to the general public because ChatGPT is losing steam.
Google is known for sticking to plans and trying to make its products work. Google doubled down on SGE in their earning’s call. And, if Google+ is any indicator, it would take quite some time for Google to kill SGE.
Google is continuing to invest in cloud technology to find growth opportunities. But right now, search advertising revenue is too important to risk making mistakes.
Another theory: The EU will get SGE much later than other regions, just like Bard.
Bard was officially released in March, but it took almost five months later to become available in the EU due to data privacy concerns.
This will serve as an opportunity for a part of the SEO community to observe what happens in first markets and to adapt accordingly.
While a lot of talk focuses on the negative impact on traffic, there are definitely some benefits.

Those were a lot of theories, so let’s focus on things we actually know now.
While an SGE overview is similar to other SERP features, like a featured snippet, it takes up much more space.
For many queries, the auto-generated overviews often fill the entire screen on desktop and require the user to scroll on mobile.
However, as you can see in the example above (for the query “how to cure depression”), the regular search features and ads also take up considerable screen real estate.
I doubt that Google will just show fewer ads, but that is what we frequently see at the moment.
If ads are added to this, either above or below the AI overview, regular organic results will get pushed down more than they do now.
Just recently, Google started showing a new layout for SGE when an overview is automatically generated. There is only a small preview and a “Show more” button. It does not fill the entire above-the-fold area or show any images of the linked sources.
Compare this AI snapshot for “credit card risk” from two different dates:
The first overview from late September was about 780px high, while the new one from early October is about 230px high – not even a third of the original size.
The organic traffic impact of the latter layout would probably be less than that of the former.
Like good YouTube thumbnails, attractive images get a higher CTR than less attractive images.
For the cited sources, this has implications for not only getting an image to show up but also being attractive for users to click on.
Consider this an avenue for optimization: show exeption images in the overview that aim to stand out against the rest.
Assuming your site does not appear in the AI overview but is highly ranked in the regular organic results, your CTR will drop.
This is natural and a no-brainer, as everything above the fold is more important on both websites and in search results.
Like any SERP with many SERP features, the CTR is affected by their appearance and placement.
In my tests, I saw fewer ads in SGE compared to regular search. This is backed by other research from Moz and Insight Partners.
These tests and studies were conducted in September, but just like Google testing the new layout, I often saw more ads appearing over time.
You can be sure that Google is testing this as much as possible to not jeopardize their search ad revenue.
As recently as late August, it was confirmed that SGE would retain sources, due to user feedback.
But that is not the only thing that has changed. After watching SGE for months, here are some other developments I have observed:
This list could go on and on.
One important point about SGE is its dynamics. Overviews for the same query are rarely 100% similar.
This brings us to things we actually don’t know.
AI overviews change often, and most of the time, the changes are drastic. See the following examples (both screenshots were taken just two weeks apart):
If your site wasn’t part of the first overview, it wouldn’t be half as bad as in the second overview, which is more than twice as big.
We simply don’t know if this will be normal for SGE, so any concrete calculations are pretty useless, especially if Google changes to a different layout, as mentioned before.
This is a complicated question with big implications. I’m sure the SEO community will develop ways to track changes in SGE over time.
There are already some suggestions for what you can do, which I will discuss in this article’s last chapter.
Microsoft promised to bring Bing Chat data into Bing Webmaster Tools.
While they delivered on that promise – albeit later than first announced – what we got is quite disappointing.
Both web and chat data are merged together with no filtering capabilities, making this data useless.
Why would Microsoft do this? Perhaps Bing Chat numbers are negligible, which is bad for PR.
My guess is that it will be many months after launch before we get data on SGE in Google Search Console.
Yes, even without official data, I’m sure SEO tool providers and smart people in the community will find ways to make them accessible.
But once again, it will take some time.
No one can say this with 100% certainty. From my observations in looking at informational queries especially, a reverse-engineering approach seems to work.
Try to see what kind of content is in the overview and what angle is covered, then find a way to present that information as clearly as possible.
However, as mentioned before, SGE elements change constantly – the angle, the answer to the same type of headline/question, and even the sources.
Let’s hope Google will provide more detailed information soon. Until then, we SEOs will have to test and see what works.
This is a tricky one. If we assume that every query generates the same type of snippet – with the same size, layout, etc. – then I would think that the CTR will be lower than for featured snippets.
But this cannot be generalized. However, it’s safe to say that it would be lower than the current number one spots for informational queries, where the CTR often ranges between 25-30%.
There are quite a few things I would advise against, whether the reader is an SEO agency, freelancer, or even a company wondering, “What can I do to prepare for and/or mitigate the effects of SGE?”
A few things summarized from this article:
To illustrate how useless any model for measuring SGE impact can be, just look at the various screenshots I provided here.
To double down on this, a colleague and I did an experiment on volatility.
Imagine two people in the same VPN searching for the same query at the same time: The result should be the same, right?
We looked at 10 different queries and checked their SGE response three times on the same day at the same time.
Out of a total of 60 observations, here’s what we found:
*Differences
Here is a direct example of the query “pros and cons of electric cars.”
This was classified as “big differences” because:
This was a fairly small sample. However, we regularly monitor SGE queries and compare the results over time.
The results of this test are no different than our other observations – SGE is as volatile as some cryptocurrencies.
There is literally very little value in investing a lot of time in models and frameworks to project traffic loss. All you need to know is that SGE will have an impact.
If your business model and current organic traffic is mostly informational, you can expect a bigger impact than if you were an ecommerce site.
But no one knows how big that impact will be, and numbers ranging from -95% to +200% for the same site are not very helpful.
Focus on the things that have an SEO impact today.
While I always say to stay vigilant and keep an eye on new developments, we should not let shiny new things distract us from what is happening right now.
There are opportunity costs associated with things you do, and the opportunity cost of investing a lot of time in SGE is much higher than improving your SEO now and preparing for changes when we know more.
You can accurately measure what you pay by doing things later. This is one of the best arguments, in my opinion.
It’s like compound interest. If you publish valuable content today, it can start to work and bring in more revenue than if published later.

What I suggest you do instead of obsessing about the possible effects of SGE is the following:
The key takeaway?
Don’t become overly fixated on SGE. Avoid listening to people trying to sell you SGE-related solutions.
No one, except Google, knows the extent and impact SGE has on organic search.
