SEO updates you need to know


๐Ÿ›’

โ€‹Google publishes a new help page for Universal Commerce Protocol. This documentation clarifies some implementation requirements for UCP and cements UCP as a core part of Google's agentic checkout.

๐Ÿ—บ๏ธ

โ€‹Yoast launches Schema Aggregation, a feature that maps all of your site's structured data. This new visualisation creates a 'schemamap' for your entire site at once, and, in theory, helps AI to understand your site's content.

๐Ÿ–ผ๏ธ

โ€‹Google clarifies how thumbnails are chosen for Search and Discover. Google updated documentation explains that it uses both schema markup and the og:image meta tag for image thumbnails in Google Search and Discover.

๐Ÿ‘

โ€‹Google says "Frequent crawling is a good sign!" The page, 'Things to know about Google's web crawling' explains that frequent crawling is an indication that "your pages have fresh or highly relevant content".

๐Ÿฅช

โ€‹Google adds a new visual presentation for recipes in AI Mode. This update adds clickable images and more links to relevant sites. Future updates will also include extra information like cooking times and related recipes.

๐Ÿคท

โ€‹Google appears unsure if Search and Gemini will converge or diverge over time. Liz Reid also stated that Google expects a future for the web where AI agents are regularly interacting with each other, not just humans.

๐Ÿ›๏ธ

โ€‹ChatGPT sources 83% of its carousel products from Google Shopping via shopping query fan-outs according to a new study, indicating OpenAI is heavily using Google results to power their answers.

๐Ÿ“ˆ

โ€‹LLM usage data (desktop) from SimilarWeb shows that Gemini is growing fast and closing the gap on a stagnent ChatGPT. However, both platforms are still dwarfed by Google Search usage.

There are two kinds of strategies, my friend

It is WILD the number of SEO practitioners that will provide a detailed SEO strategy after 30min of speaking to a client about their business. Some things I like to consider โฌ‡
โ€‹
Generally, we start with auditing to find out things like:
โ€‹
๐Ÿ’ป How much technical input will we need? Is there anything that will hamper our other efforts? Are we sitting on unrealised potential?
โ€‹
๐Ÿ“– What has the client tried before? What is currently working well? What is not working well? What currently exists? At what magnitude?
โ€‹
๐Ÿƒโ€โ™‚๏ธ What are successful competitors doing differently? At what scale? How far behind at we?
โ€‹
๐ŸŽฏ Does our plan complement business objectives? Does it work with the clientโ€™s brand?
โ€‹
โŒ› What resources do we have to execute? What is the budget? What internal resources and skills does the client have? What is the time frame?
โ€‹
There are a lot of things you won't know going into an engagement and it's likely there are a lot of things your client doesn't know about SEO.
โ€‹
This area of unknown unknowns is a dangerous place to make decisions from!

I've never seen so much SEO wasted so badly

Golden rule of SEO:

There is absolutely no 'SEO change' you should do on your site that will make the user experience worse.

None.

No exceptions. ๐Ÿ™‚โ€โ†”๏ธ

I'll keep the SEO, you can have the GEO

The biggest 'GEO' levers you can pull are nothing to do with 'chunking' or llms.txt. I get these all the time and I am doing no 'GEO'.

Most people aren't doing fundamentals in a coherent and consistent way.

Unpopular? Yes.

True? Also, yes.

You have a site beautiful enough to be worth two thousand dollars

How much should a site migration cost? There is actually a pretty easy answer to this, whether you are an SEO or a business owner ๐Ÿ’ธ
โ€‹
๐Ÿš— While opportunities can present themselves, a 'true' migration is primarily a risk mitigation activity, so think in these terms. You shouldn't invest a larger sum in a site migration than the value of the risk you are mitigating. It makes sense in the same way you wouldn't agree to $5,000 a year insurance on a car that you bought for $1,000.
โ€‹
โš–๏ธ Quantifying risk can be tricky, but a rule of thumb I apply is applying the chance of the risk happening against the value of the risk. This means if I decide I have $10,000 of value at risk, but there is a 50% chance, I simplify that to a $5,000 risk, as that is what I will lose on average.
โ€‹
๐Ÿ—’๏ธ At Candour we will conduct risk assessments for migration, which look at dozens of factors to try and calculate the risk. Here are just 3 things we look at that I think are important:
โ€‹
1๏ธโƒฃ Branded vs unbranded traffic split. In general branded traffic is very difficult to lose, so high percentage of branded traffic makes migrations less risky, whereas reliance on lots of unbranded traffic means it could easily go elsewhere.
โ€‹
2๏ธโƒฃ Traffic split over # of pages. If 90% of your traffic is landing on your homepage, the complexity and risk of the migration is likely low. If 90% of your traffic is spread over 9,000 pages, there is a lot more that can potentially go wrong.
โ€‹
3๏ธโƒฃ How closely the new site mirrors the current site. Multiple migrations (URLs, CMS, server, etc) carry a much higher risk than maintaining parity.
โ€‹
There is a lot to consider, but when you go through these factors you will soon realise that migrations are not a thing to be rushed! ๐Ÿฆ†

When you have to disavow, disavow. Don't talk.

I have seen lots of credible evidence from people like Martin McGarry that the disavow file is still effective at fighting particularly brutal link spam. (In almost all cases you shouldn't be touching it though)
โ€‹
