​AI Overviews reduce clicks by 34.5% according to a new study of 300,000 keywords by Ahrefs. The test backs up reports of site owners suggesting a 20-40% reduction in clicks as AIOs rolled out.

πŸ“‘

​Site Stats Database has released a free version with data on 10,000 domains, allowing you to find low DA/high traffic sites, filter for HCU/Core Update recoveries, sort by monetisation, language, niche and more.

🌳

​Highlighting the inaccuracy of AIOs, it was discovered adding "meaning" onto the end of any query will generate a definition for any fabricated saying - with Google saying "fish fingers up a tree" was a common British English phrase.

πŸ‘Ž

​Google's John Mueller downplayed the usefulness of LLMs.txt, comparing it to the keyword meta tag, which accuractly reflects the experience of webmaster that have used it. Not sure what you were expecting.

πŸ“Ή

​Google has been testing showing an animated/playable video in the shopping block card, a feature which they launched as a test several months ago. In full screen, it shows related products and topics which launch new queries.

πŸ“Š

​Google Analytics is rolling out major updates aimed at sharpening marketing insights – boosting data completeness, adding richer context, and flagging issues before they become problems.

🌎

​Google has begun a project rolling all of its ccTLDs into their dot com domain. This means local versions such as .co.uk, .de, .au will no longer exist. Google has confirmed there should be no impact for SEOs/webmasters.

πŸ€–

​The Agent2Agent protocol was announced at Google's Cloud Next 2025 event, which could radically change how the web works, with Google saying "every enterprise will soon rely on multi-agent systems".

πŸ›οΈ

​New code in ChatGPT’s public web bundle indicates they are poised for a Shopify partnership to bring in-chat shopping, with references to price, shipping, and "shopify_checkout_url" snippets.

How to start an SEO agency

Season 4: Episode 16

This week, Jack Chambers-Ward is joined by returning guest Matt Kohli.

Together they discuss Matt's journey from being a freelancer to founding Fortitude Marketing.

The conversation covers the challenges of transitioning roles, the importance of building a reliable team, learning to trust others, and strategically planning for long-term success. They also highlight the importance of not overpromising to clients and focusing on delivering results.

This week's solicited tips:

​

City-level searches now available on AlsoAsked

⭐HUGE⭐ new feature on AlsoAsked today: the ability to specify city location, on a worldwide basis! πŸ™οΈ

Big credit to user Arnout Hellemans who showed me that Google appeared to be doing some quite precise geographic targeting (for US searches on 'food trucks') - and further investigation showed this seems to be happening on a much more widespread basis.

So, the R&D began and we've finally rolled out the ability to specify city with your search to ensure you are getting the highest quality data. πŸ”₯

😎 I believe this makes AlsoAsked the only PAA research tool on the planet that offers live PAA data on a city level (and still the only one with async API to this data) - just in time for brightonSEO!

....new AIO features coming soon!

Sometimes, you just need to wait...

This is a one page experiment website. Do you want to know the ranking secret that took it from 800 to 9,000 clicks a month? πŸ™ƒ
​
After seeing a niche I thought might work, I wrote 1 page of content, I secured 3-4 links and then......
​
Nothing. I waited for 6 months πŸ¦—πŸ¦—πŸ¦—
​
A component of SEO is time. ⏳
​
I knew it provided value, and Google would learn this over time. As Daniel Foley Carter highlighted in his brightonSEO talk, and as I've discussed with people like Arnout Hellemans - Google sometimes just wants an assessment period, and if you keep chopping and changing things, you can sometimes shoot yourself in the foot.

Advanced SEO really can defeat the HCU

Content is assessed in context to the site it is delivered on. Good content is table stakes, not an SEO differentiator. 🀌
​
This is why you can take content that isn't ranking - or has even been specifically supressed by the "Helpful Content Update" and transplant it to another website, where it will immediately rank number one. πŸ“ˆ
​
The content is not as important as you think in regard to the wider ranking picture. Too many clients coming to us with traffic decline obsessing over fiddling with content when there are much larger bits of the jigsaw missing. 🧩

​Here is a fun example from a couple of months ago of a site that had 99.9% traffic loss because of the HCU - was it the content? ‡️

What are LLMs saying about you?

While I am sceptical on "GEO", it is certainly a fact that search behaviour is fragmenting and shifting with many LLM-powered systems being used. One of the key problems that I know people like Emilia Korczynska have encountered is these kind of systems returning false information about their products/services. ❌
​
I am currently slowly experimenting with the features on Waikay (What AI Knows About You) that Dixon Jones introduced me to.
​
One of the cool things it can do is fish out some "facts" from various LLMs about your product so you can get a sense for what kind of imprint as been made.
​
While some of these will be a product of training data, I can see particularly bad ones being "solved" during a grounding process if new content was published on trusted sites that contradicts these statements.
​
I've been impressed so far - the link is https://waikay.io/​
​
[I'm also experimenting putting links in posts as Nikki Pilkington showed me some data this will apparently be fine!]
​
Here is some AlsoAsked facts from LLMs ‡️

XML Sitemap can make indexed URL comparison easy

I would always recommend having an external XML sitemap as it provides an easily audible list of indexable/canonical URLs. This makes it much easier to spot when rogue URLs are either linked to or are present in the index and getting traffic.
