Last week, our agency experienced a typical conflict for this year. Client Oleg invested substantial money in comprehensive SEO promotion your online store of building materials. We did an excellent job: we ousted our competitors and secured our position in first place for all commercial requests. According to the old rules of the game, this meant a stir at the box office. But Oleg looked at the analytics with horror - traffic not only did not grow, it fell by 30%.

“Are you deceiving me? I type my request in Yandex, and the first result is you! But for some reason people don’t cross over!”

He was right and he was wrong. We didn't cheat. Simply, the rules of the game have changed forever. What he witnessed was the greatest disruption of search marketing in the last 15 years. If you still think that SEO website promotion - it’s easy to write texts and build links, you urgently need to understand the difference between three letters: SEO, AEO and GEO.

SEO: Good old classics that are slowly dying

Let's start with the base. What is SEO (Search Engine Optimization)? It is the art of making your website crawler friendly so that they rank you in the top 10 blue links.

For many years it was an unchanged formula: found keywords, wrote texts, set up internal website optimization, increased authority external website optimization (links). It worked flawlessly. A person searched for “buy concrete M500”, saw you in the first place, clicked, went to the site, read, called.

SEO is not dead yet, it is foundational. Without a competent technical base, your site will not be indexed at all. But now turnkey SEO promotion became just a ticket to enter the building. You are at the top, but you are standing in an empty hall, because the audience has gone to another hall, where a new presenter is working.

AEO: War for Zero Position (Quick Answers)

While you and I were fighting for a place in the top 10, search engines realized one thing: a person most often does not need a whole website. He just needs an answer to the question.

Then it came on stage what is AEO (Answer Engine Optimization - optimization for response engines). You've probably seen this: you enter a query, and above the first links there is a block with the text “Quick answer” or a table.

When a user searches for “how much does a cube of concrete cost,” they don’t need to go to your website to scroll through the price list. The Yandex neural network has already pulled your number directly into the search. If you haven't optimized your content for get into Yandex quick answers, you may be first in the search results, but they won’t click on you.

At the DOM-Marketing agency, we began to change our approach: we force clients to put exact prices and characteristics in tables and lists right at the beginning of the article. We use markup to indicate to the robot: “Hey, here is the exact answer, take it!” If you are planning order website development from scratch, this architecture should be laid out at the design stage.

GEO: The Monster That Eats Clicks

And now we come to 2026. The AEO era is just a warm-up compared to what's going on now.

What is GEO (Generative Engine Optimization)? This is adapting your content for generative search. Have you noticed a huge block with an answer from YandexGPT that appeared in the search? This is GEO.

The neural network no longer searches for a site for the user. She reads thousands of sites, synthesizes information and produces its own unique answer, writing at the bottom in small print: “Based on data: site A, site B.”

For business, this is a blow below the belt. You can do it for years website promotion in search engines, to be an ideal resource, but if YandexGPT decided that two of your competitors are enough to generate an answer, you will simply be thrown out of sight. Promotion in neural networks - this is now a battle not for a click, but for the algorithm to generally recognize you as a source of truth. This requires a completely different approach to expertise (E-E-A-T), structuring data, and even introducing new standards, like the LLMS.txt file, which tells the neural network exactly how to use your content. If you need implementation of AI in business, you must start with GEO.

How we returned traffic to Oleg

Let's return to our builder. The problem wasn't that we didn't do a good job of SEO. The problem was that his website looked like a structureless sheet of text to the AI.

We stopped writing watery 5,000 word articles. We divided product cards into rigid logical blocks. We've added Frequently Asked Questions (FAQs) with direct answers to common pain points. We have added the LLMS.txt file. Two months later, a miracle happened: the click-through rate began to increase. Why? Because we got into the responses of neural networks. YandexGPT began citing Oleg’s store in its blocks, and people, seeing his name there, still clicked on the link to find out more details.

The world of search has changed. SEO no longer exists in a vacuum. If your seo agency are still selling you only “link profile building”, they are leading you into the abyss.

IN DOM-Marketing we rebuilt all our processes. We integrate classic technical optimization with new AEO and GEO rules. You can see how we adapt businesses to the new reality in our completed cases. And remember, any complex system needs constant monitoring so as not to fall out of generative output - for this we provide reliable technical support.

Stop playing by yesterday's rules. Make neural networks work for you.
