AI & SEO Trends Update - 18th September 2026

Since our last AI and SEO trends update, the search industry has recorded further volatility in Google’s rankings, including some significant changes that later reversed.

New data also suggests people are using longer, more specific search queries, while OpenAI has introduced conversational advertising tools that could change how customers research businesses through ChatGPT.

Recap: What We Covered Last Time

Our previous update focused on Google’s August spam update. Google introduced no new policies and did not identify AI-generated content as a specific target. The update instead strengthened the enforcement of existing policies covering practices such as scaled content abuse, scraping and doorway pages.

We also explored new research into Gemini citations, changes to ChatGPT’s source selection and Microsoft Clarity’s AI referral reporting.

Google Rankings Remain Volatile in September

Google’s organic search results have experienced further volatility during September, although Google has not confirmed a new ranking update.

Industry monitoring identified notable movement around 4th September. Some large websites experienced sharp declines across Search and Google Discover, before recovering suddenly around 13th September.

Search Engine Roundtable reported that the changes were visible across third-party ranking tools and, for some affected websites, within first-party analytics data. This suggests the movement reflected genuine traffic and visibility changes rather than fluctuations within individual tracking platforms.

Further volatility was recorded around 15th September, accompanied by increased discussion among website owners reporting changes to rankings, traffic and conversions.

However, Google’s Search Status Dashboard lists the August spam update as its most recent confirmed ranking update. The September movement should therefore be treated as unconfirmed volatility rather than a named Google update.

It is also unclear whether this activity was connected to the August spam update, a separate adjustment or routine changes to Google’s ranking systems.

What This Means For You

If your organic performance changed during September, note the following:

• 3rd–4th September: initial ranking movement
• 13th September: reversals and recoveries reported for some websites
• 15th September onwards: further volatility observed

Avoid making major changes in response to a short-term decline. Some websites affected at the beginning of September recovered without substantial action, demonstrating why it is important to wait for a consistent pattern.

Review whether changes affected individual pages, particular query groups or the whole website. Rankings should also be considered alongside clicks, conversions and enquiries, as movement within tracking tools does not always translate into a meaningful commercial impact.

We will continue monitoring performance and Google’s official communications for evidence of a broader update.

Search Queries Are Becoming Longer and More Specific

An analysis of Google Ads search-term data suggests that users are increasingly moving away from short, keyword-led searches and towards longer, more detailed queries.

Within the dataset, one or two-word searches fell from 42% of impressions in January 2025 to 24% in August 2026. Three or four-word searches increased from 33% to 48%.

Longer queries also generated a growing share of conversions. This indicates that people may be providing more context as they search, particularly when they are closer to making a decision.

The findings come from one advertising dataset and should not be treated as representative of every industry. However, they support a broader shift towards more conversational and specific search behaviour.

What This Means For You

Keyword research remains important, but individual keywords should not be considered in isolation.

Content and landing pages should answer the detailed questions customers ask while comparing providers, products or approaches. These could cover suitability, costs, limitations, implementation, alternatives and expected results.

This can strengthen visibility across traditional search while making content easier for AI systems to retrieve when responding to more complex prompts.

OpenAI Introduces Sponsored Agents

OpenAI has announced several additions to ChatGPT Ads, including Sponsored Agents.

These allow users to choose to begin a clearly labelled conversation with a business-sponsored agent after selecting an advert. They can then ask follow-up questions about a product or service before visiting the advertiser’s website.

Sponsored Agents are initially being tested with selected US advertisers. OpenAI has also introduced natural-language campaign management and integrations with HubSpot and Shopify.

Organic ChatGPT answers and sponsored conversations remain separate. However, the development shows how AI platforms could shorten the journey between discovering a business, researching its offer and taking action.

What This Means For You

Businesses should continue treating paid and organic AI visibility as distinct channels.

For both, clear product and service information will become increasingly important. Pricing factors, suitability, evidence, availability and next steps should be easy for customers and AI systems to understand.

Google Tests Payments for Content Used in AI Answers

Google is also testing an ‘AI contribution’ pilot that rewards selected publishers when their content significantly contributes to responses in Gemini, AI Overviews or AI Mode.

According to Digiday, participating publishers receive an additional section within Search Console showing monthly earnings. Google has not disclosed how contributions or payments are calculated.

The pilot is not currently available to most businesses. However, it provides another indication that original, accurate and regularly updated source material has value within AI search.

Conclusion

The latest developments show that search visibility is becoming more complex and less predictable.

September’s ranking volatility reinforces the importance of assessing sustained performance rather than reacting to individual daily movements. Meanwhile, longer search queries and conversational advertising demonstrate how customer journeys are becoming more detailed and interactive.

Businesses should continue investing in useful content, clear commercial information, technical accessibility and original evidence that supports visibility across search engines and AI platforms.
