It’s been an interesting year for SEO. In 2025, search habits rapidly shifted, AI-driven answers became an increasingly normal part of how people look things up, and major platforms like Google rolled out some big updates.

All of these changes gave marketers plenty to keep up with! Here’s a look at the top SEO developments from the past year.

1. AI-Powered Search Moves Into the Mainstream

Everyday search habits have undergone a massive shift over the past year, with consumers increasingly defaulting to AI-powered search as their go-to. Just a few stats that illustrate this change:

• Half of consumers – spanning all ages and including a majority of baby boomers – now opt to use AI-powered search engines, with a majority of them saying it’s their top digital source when making buying decisions.
• AI summaries already appear in about 50 percent of Google searches today, with that number projected to reach 75 percent in the next few years.
• By 2028, $750 billion of U.S. consumer spend will funnel through AI-powered search.
• Brands unprepared for this shift may see traffic decline from traditional search channels – anywhere from 20 to 50 percent.

These changes happened fast. And now, with AI-powered search becoming a primary entry point for online discovery, space has opened up for new tools and platforms to compete for user attention. In 2025, that competition became a lot more visible.

2. ChatGPT Search Emerges

Google is still unquestionably the king of search, but there’s a new kid on the block. ChatGPT Search officially debuted one year ago, offering a way to search the web directly within its chat interface. The feature blends live web results with model-generated context, providing clickable links to sources, and it can refine searches through follow-up questions and answers. 

ChatGPT Search is a perfect example of the ongoing shift in how people interact with information online. Its conversational format is easy to use – a lot more intuitive and accessible than relying on your “Google-fu” skills to get the results you’re looking for!

But at the same time, the rise of AI-led search is changing the game for marketers. Google’s AI Overviews, Bing’s Copilot Search, and true answer engines like Perplexity all expect content to do more. It has to appeal to human readers and traditional search engine algorithms as well as to AI models that decide which pieces are pulled into an answer.

3. The Rise of AEO and GEO

In 2025, Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) became a crucial area of focus for marketers. They involve optimizing for AI-friendly formats – keeping in mind how large language models interpret content and shaping information so it’s more likely to appear in AI-generated answers. 

In other words, you want to be the answer rather than just get the click.

What’s the best way to do this? Well, just like with traditional SEO, there’s no exact formula for AEO and GEO. However, some best practices include:

• Focusing on user intent in natural language rather than exact phrase matching.
• Providing clear and concise answers to granular questions, with self-contained ideas that make it easier for models to extract the right snippet.
• Incorporating citations or statistics that models can reference. And don’t forget authoritative sourcing!

Visibility depends on how well AI systems can understand and trust your content. The catch is that even perfectly optimized pages can be summarized by AI before anyone clicks through.

4. Zero-Click Behavior Accelerates

Clicks don’t carry the same weight anymore. As AI-generated answers became more accurate and more common in search this year, users increasingly got what they were looking for without actually clicking through to a website. 

A recent study found that since Google rolled out AI Overviews a year and a half ago, organic and paid click-through rates (CTRs) have dropped 61 percent and 68 percent respectively. 

Even when a page is cited in an AI Overview, click-throughs are still much lower than they used to be. On the plus side, cited brands consistently outperform those that aren’t. And interestingly, AI Overviews don’t just reinforce the usual winners: only about 15 percent of Overview citations overlap with the top ten organic search results.

In this new reality, marketers need to rethink how they measure performance. Getting content pulled into an AI-generated answer can make a big difference – and that’s an advantage that smaller brands can use to their benefit.

5. Google Updates Raise the Bar on Quality

Google released a series of updates this year, starting with the March and June core updates. These brought improvements to Google’s ability to surface relevant content and comprehensively interpret patterns of trustworthiness. Brand authority signals may also influence rankings more than before.

The August update was aggressive, designed to cut down on bulk AI-generated pages and overly templated content. Google has long emphasized people-first content, but as AI tools flood the web with look-alike material, the bar for originality and quality is getting higher. 

Users are also increasingly looking for authenticity as the “dead Internet” theory no longer seems so far-fetched. Google’s updates reflect this shift: content that displays real-world signals and that feels human is more important than ever. 

6. Instagram Content Now Searchable on Google

Starting in July, public content from professional Instagram accounts became searchable through Google and other search engines. This change offers a whole new path to visibility for creators and brands. Before, Instagram posts were basically walled off from the open web, whereas now they can contribute to a brand’s broader search presence.

Visually driven content is also becoming more important in search results as visual and voice-led discovery continues to rise. People increasingly search using their camera, for instance, and Instagram’s image-heavy posts are well suited for that kind of intent.

It’s a reminder for marketers to treat social content as a search asset and not just a standalone channel.

Final Thoughts

If 2025 has shown us anything, it’s that SEO is a constantly moving target. 

But even with all of the past year’s changes and new trends – in user habits, AI-driven search, new features, and more – the old principles still apply. Useful, people-first content still matters just as much as it always has. The challenge now is to adapt it to how and where people look for information today. 

And with how fast things are moving, next year should be a fun one to watch!
