March 2026 Google Discover Core Update Is Done Rolling Out After 3 Weeks https://www.seroundtable.com/february-2026-google-discover-core-update-done-41006.html Barry Schwartz brings you this news about Google’s latest Discover Core Update. This three-week overhaul finished with major changes for sites that depend on news content and the Discover tab. As a result of the update, local articles will be much more likely to be surfaced than those that are published in more distant regions. In particular, Google said the updates were likely to prevent non-US publishers (especially clickbaity ones) from showing up in the US. In a statement posted after the core update, Google stated the changes were meant to show more original content from sites with expertise. This update followed a series of others that penalized spam and general websites. You should check out the changes to the Discover documentation if you have a site in the news vertical. Also, check out the full article for discussions from top SEO communities on how these effects are being felt. Discover isn’t the only place where the SEO game is getting harder.

They also talk about the nuts and bolts of building agency SEO plans, and how AI can increasingly be used for some of the most tedious tasks, including internal linking and content optimization.

Next, there’s some new research on ChatGPT traffic, and it may be far more valuable than you thought. ChatGPT Traffic Converts 31% Better than Non-Branded Organic Search (94 eCommerce Sites Analyzed) https://visibilitylabs.ai/chatgpt-vs-organic-search-conversion-rates/ Jeff Oxford brings you this study of 12 months of Google Analytics data from 94 eCommerce stores (7-8-figure brands generating more than $30 million in revenue). In this massive test, Jeff and his team tracked organic and ChatGPT sessions that occurred across all tracked stores. They intentionally excluded homepage traffic and blog posts from the results. This kept the comparison focused on commercial intent. ChatGPT traffic beat organic traffic for 10 of the 12 months that the study lasted. Jeff and his team did their best to understand why. He suggests the difference appears because ChatGPT users refine their needs before clicking. ChatGPT users arrive ready to evaluate and purchase, not to browse. Check out the complete study to learn more insights the team uncovered, including extra stats on traffic, revenue per session, average order value, and other information that could inform your next big moves. Speaking of big moves, one team outsourced a marketing strategy to AI. In the next piece, you’ll learn what happened. I Outsourced our Digital Marketing to AI. Here’s What Happened https://www.youtube.com/watch?v=3iNJeArrUu4 Sam Oh brings you this look at the results when you just hand over the marketing strategy to agents. This was just a fun test, but it shows some of the amazing early potential of agents and gives you an idea of what they can really do. For the test, Sam fed ChatGPT a year’s worth of product update blog posts. He built a custom project around the library of information he provided, wrote instructions for the bots, iterated on tone and style, and then tested the system on three deliverables that actually ship. His team gave the agents responsibility for a product updates blog post, a YouTube script, and a newsletter that goes to tens of thousands of people. They evaluated where AI content shines for speed, where it breaks without context, and what happens when brand voice collides with generative outputs. Sam wasn’t aiming for perfection. He planned ahead to aim for “about 80% there”. He and Tim Soulo evaluated each one based on their team’s high standards. The results were mixed. Tim was able to identify most AI examples and provided some interesting insights on how he applied standards and recognized flaws. Check out the full video for a breakdown of how the AI performed across each content type. Are you building the right content? Search is being monetized in new ways, and the next piece can help you understand how. Search isn’t Just Turning to AI; it’s being Re-Monetized: Text Ads Are Taking a Bigger Share of Google SERP Clicks (Data) https://www.aleydasolis.com/en/search-engine-optimization/serp-shifts-ads-remonetized/ Aleyda Solis brings you this look at where the money in search is really going. While AI is often blamed, she argues that another cause lies in the data. Her hypothesis was that the increase in text ads (as well as organic SERP features) could also be responsible for the decrease in classic organic search clicks across different verticals, potentially even more so than AIOs. She used Similarweb data to analyze the SERP composition evolution across four verticals. She chose the top 5,000 queries for headphones, jeans, and online games (plus the top 956 queries for greeting cards & ecards in the US). For each vertical, she tracked click distribution for classic organic results, organic SERP features, text ads, PLAs, zero-click searches, and AI Overviews. In every vertical, she discovered major shifts. For example, in just headphones, she found that classic organic click share dropped from 73% to 50%. This was a 23% decline in a single year. She also discovered that: She breaks down who appears to be benefiting most from these changes in each vertical. For example, with headphones, she found that YouTube is the big winner. It jumped from #2 (178K clicks) to #1 (244K). Check out the complete article to get data and analysis for all four of the verticals she covered in her research. You’ll also find a lot more about who is winning and losing organic traffic, and who is buying these clicks. Next up, a social media marketer predicts the end of social media. AI is Ending the Social Media Era and What Comes Next https://www.youtube.com/watch?v=sUvWVF28CNM Sinead Bovell interviews and debates Gary Vee about the possible end of the social media era from the perspectives of creators who need to reach an audience. Their talk covers why social media marketers are saying the end is near, how pros are adapting to AI, and more. Both hosts agree that one of the biggest changes (AI) is here to stay. They acknowledge some struggles with AI creator tools but agree that new technologies are always clumsy before they transform everything. They also cover some trends that may doom social media. For example, they discuss how younger consumers’ habits are changing, turning away from social media toward real-life experiences or personality-led spaces online. The news isn’t all bad for creators who depend on social media. The host and guest have a lot to say about how brands and creators can continue to break through in a new AI-driven economy. They also speculate on the future of entertainment after social media and how creators can start crafting more immersive experiences. Check out the full video for a spirited discussion about what comes next and how creators should be preparing. If your future visibility depends on AI, you may be making some mistakes you can fix.
