Welcome to the week\u2019s Pulse: updates affect when you can start analyzing core update performance, how much you can trust your impression data, and what Google\u2019s CEO thinks AI will do to software security.<\/p>
Here\u2019s what matters for you and your work.<\/p>
Google\u2019s March 2026 core update finished rolling out on April 8. The Google Search Status Dashboard confirms the completion.<\/p>
Key facts:<\/strong> The rollout took 12 days, starting March 27 and finishing April 8. That\u2019s within Google\u2019s two-week estimate and faster than the December update, which took 18 days. Google called it \u201ca regular update\u201d and didn\u2019t publish a companion blog post or new guidance. This was the third confirmed update in roughly five weeks, following the February Discover core update and the March spam update.<\/p> You can now run a clean before-and-after comparison in Search Console. Google recommends waiting at least one full week after completion before drawing conclusions, which means mid-April is the earliest window for reliable analysis.<\/p> A ranking drop after a core update does not mean your site violated a policy. Core updates reassess content quality across the web. Some pages move up while others move down. Roger Montti, writing for Search Engine Journal, suggested the spam-then-core sequencing may not have been a coincidence, describing it as clearing the table before recalibrating quality signals.<\/p> Lily Ray, VP, SEO & AI Search at Amsive, noted on X that YouTube has gained visibility since the core update began rolling out:<\/p> \u201cJust checked a client that ranked in AI Overviews last week and now the top 4 links in AI Overviews are all YouTube.<\/p> Let me guess: the core update was another way for Google to boost YouTube, like it did with the Discover core update.\u201d<\/p> <\/blockquote> Aleyda Sol\u00eds, SEO consultant and founder of Orainti, is running a poll on LinkedIn asking how the update impacted peoples\u2019 websites. Currently, most respondants say the impact of the update with either positve or not noticeable.<\/p> Read our full coverage: Google Confirms March 2026 Core Update Is Complete<\/p> Google confirmed a logging error in Search Console that over-reported impressions starting May 13, 2025. The company updated its Data Anomalies page on April 3 to acknowledge the issue.<\/p> Key facts:<\/strong> The bug ran for nearly 11 months before Google publicly acknowledged it. Clicks and other metrics were not affected. Google said the fix will roll out over the next several weeks, and sites may see a decrease in reported impressions during that period.<\/p> If your impression numbers have looked unusually healthy since last May, this bug is likely part of the reason. The correction will change what your Performance report shows, but it will not change how your site actually performed in search. The impressions were logged incorrectly. Your actual visibility may not have changed.<\/p> Teams that reported impression-based metrics to clients or stakeholders since May were working with inflated numbers. Click data provides a cleaner signal for performance analysis while the fix rolls out. Treat May 13, 2025 as a data annotation point, similar to how you would mark an algorithm update date in your reporting.<\/p> Brodie Clark, independent SEO consultant, flagged the issue on March 30, four days before Google\u2019s acknowledgment. He wrote:<\/p> \u201cHeads-up: there is something bizarre going on with Google Search Console data right now.<\/p> Similar to the changes that came to light after the disabling of &num=100, impressions are again skyrocketing for specific surfaces on desktop.\u201d<\/p> <\/blockquote> Clark documented impression spikes across merchant listings and Google Images filters on multiple ecommerce sites and called for the Search Console team to investigate.<\/p> Chris Long, co-founder of Nectiv, wrote on LinkedIn: \u201cHoly moly SEOs. It turns out Google has been accidentally inflating impressions in Search Console reports for ALMOST A YEAR.\u201d Long noted that Google did not indicate how much impressions would decrease, and that the profiles he checked appeared stable so far.<\/p> Source: Google Data Anomalies in Search Console<\/p> Google CEO Sundar Pichai said AI models are \u201cgoing to break pretty much all software out there\u201d during a podcast conversation with Stripe CEO Patrick Collison. The interview covered AI infrastructure constraints and security risks.<\/p> Key facts:<\/strong> Pichai framed software security as a hidden constraint on AI deployment alongside memory supply and energy. When investor Elad Gil mentioned hearing that black market zero-day prices were falling because AI was increasing the supply of discoverable vulnerabilities, Pichai said he was \u201cnot at all surprised.\u201d<\/p> The security conversation may feel distant from daily SEO work, but it connects to the infrastructure your sites run on. If AI accelerates the pace at which vulnerabilities are found and exploited, the window between a flaw existing and an attacker using it gets shorter. That puts more pressure on maintaining current patches and auditing dependencies.<\/p> Pichai\u2019s comments were conversational, not a formal Google policy statement. But they came from someone who oversees both the company\u2019s AI models and its threat intelligence operation. Google\u2019s threat teams have been warning about software security risks tied to faster vulnerability discovery.<\/p> Read our full coverage: Pichai Says AI Could \u2018Break Pretty Much All Software\u2019<\/p> Google\u2019s John Mueller responded to a blog post by SEO professional Preeti Gupta about how the word \u201cguru\u201d is misused in the SEO industry. Mueller shared his view on Bluesky.<\/p> Key facts:<\/strong> Mueller wrote:<\/p> \u201cTo me, when someone self-declares themselves as an SEO guru, it\u2019s an extremely obvious sign that they\u2019re a clueless imposter. SEO is not belief-based, nobody knows everything, and it changes over time. You have to acknowledge that you were wrong at times, learn, and practice more.\u201d<\/p> <\/blockquote> Gupta\u2019s original post explained that in India the word guru carries deep cultural and spiritual meaning that is trivialized when SEO practitioners use it as a self-applied label.<\/p> The core of what Mueller said is that SEO changes over time and that nobody has it all figured out.<\/p> Just look at what happened this week. Core updates continue to happen without a clear explanation of what changed. A basic logging bug in Search Console went unnoticed for nearly a year. The tools and signals we rely on every day are imperfect, and treating any methodology or perspective as settled knowledge is how mistakes get made.<\/p> Read Roger Montti\u2019s full coverage: Google\u2019s Mueller On SEO Gurus Who Are \u201cClueless Imposters\u201d<\/p> The speculation about where search is going has never been louder. But this week\u2019s events were a core update finishing, a data bug getting patched, and a Google Search Advocate reminding people that nobody has all the answers.<\/p> The future Pichai describes may be coming, but it hasn\u2019t arrived yet. Right now, the job is still reading your Search Console data, waiting for a core update to settle, and staying honest about what you do and do not know.<\/p> Mueller\u2019s comment that SEO \u201cis not belief-based\u201d and \u201cchanges over time\u201d is as good a summary of this week as any. Those who will succeed in the next version of search are probably the ones paying attention to this version first.<\/p> Top Stories Of The Week:<\/strong><\/p> Here are the main links from this week\u2019s coverage.<\/p> More Resources:<\/strong><\/p> For more context, these earlier stories help fill in the background.<\/p> Featured Image: [Photographer]\/Shutterstock<\/em><\/p> <\/div> SEO,SEO Pulse#Core #Update #GSC #Bug #Fixed #Mueller #Gurus #SEO #Pulse #sejournal #MattGSouthern1775827169<\/p> ","protected":false},"excerpt":{"rendered":" Welcome to the week\u2019s Pulse: updates affect when you can start analyzing core update performance, how much you can trust your impression data, and what Google\u2019s CEO thinks AI will do to software security.
