LinkedIn now runs 40% AI-generated content. Google may ignore your robots.txt, and search rewards creator authority over domain authority. Here is what changed.
Hi Marketers,
Welcome to the new issue of HighDegree*: Cutting Through the Noise in SEO & Digital Marketing.
This week we have data, a technical gotcha, and a model shift that reframes everything else. LinkedIn is more AI-saturated than any other social platform, and the numbers are not close. Your robots.txt file may be silently ignored by Google for a reason most site owners never catch.
Google’s CMO of 22 years shared the three principles that have held up through every product shift the company has made. Ahrefs laid out 10 ways to actually use AI for writing without producing slop. And Moz made the case that Google is now running on creator-platform logic, which changes what visibility means at a structural level.
Let’s jump in.

➞ LinkedIn Is Drowning in AI Content, and the Data Proves It
Pangram Labs scanned over one million social media posts across LinkedIn, X/Twitter, Reddit, Medium, and Substack using opt-in data from their Chrome extension. The average AI-generation rate across all platforms was 13.8%. LinkedIn was worse: more than 40% of longform posts flagged as fully AI-generated. LinkedIn made up a third of scanned posts but accounted for nearly two-thirds of all AI content flagged in the study.
The counterintuitive part is that identity-tied professional content is the most AI-saturated, not the least. LinkedIn nudges this along with a built-in writing assistant, now labeled “Enhance post.” Replies look different: on Reddit, 98.1% of replies were fully human-authored, while top-level Reddit posts hit 11.6% AI saturation. If you write original, specific, personal content on LinkedIn, you are the exception now. That gap is real, and it will not last forever.

The AI slop problem in your feed is one issue. The harder question is whether there is a right way to work with AI that does not make you part of the problem.
➞ Write with AI Without Wrecking Your Voice: 10 Methods That Actually Work
Ahrefs’ Mateusz Makosiewicz argues AI has been almost universally misused for content, then lays out 10 methods his team runs in production. None of them are “paste a keyword and hit generate.” Vibewriting means steering a rough draft through iterative feedback rather than prompting a finished piece in one shot. The Living Draft method keeps a topic permanently open, feeding new links and ideas as you find them until the structure reveals itself. The AI interview method asks the model to question you like a journalist, one question at a time, surfacing ideas you had not yet organized.
Other methods include pointing AI at your existing published content to assemble new articles from knowledge you already have, and running 100-angle brainstorms to find angles nobody in your niche has covered. For repeatable formats like release notes or landing pages, a staged pipeline where AI handles each step and you approve at checkpoints keeps quality consistent. Every method requires you to stay involved. The output quality tracks how much thinking you put in.

Knowing how to use AI well is one skill. Knowing which marketing philosophy survives every platform shift is another, and Google’s own CMO has been stress-testing that for over two decades.
➞ Google’s CMO Has Run Marketing for 22 Years: Here’s What She Learned
Lorraine Twohill joined Google in 2003, before Gmail, Maps, or YouTube existed. Interviewed live at Cannes Lions, she shared three principles that have held through every shift the company has made. First: be the voice of the user. She pushed for Google’s first major ad budget to fund an emotional brand campaign for Chrome rather than pure performance spend. The campaign ran country by country and turned an unknown browser into the dominant one. Work that makes people feel something, she argues, outperforms work that only prompts them to act.
Second, treat agility as a personal skill, not a team process. She describes careers as a jungle gym, not a ladder. Third, hire for attitude over resume. She looks for “quick twitch” generalists with high curiosity who can pivot fast rather than specialists with deep domain expertise in one vertical. She does acknowledge that specialists are now essential for AI-specific roles like media measurement and research. But her default hire is someone who can rewrite the playbook when the tools underneath it change.

Strategy and hiring principles hold at every level. But there is a technical issue right now that is quietly tanking SEO work regardless of how good the strategy is.
➞ Your Robots.txt May Be Lying to You About What Google Can Index
Google’s John Mueller explained a robots.txt quirk that is catching site owners off guard. A Shopify store getting hit by search box spam had added a disallow rule under “user-agent: *” to stop Google from indexing spammy search-generated URLs. Google ignored it. Mueller found why: the file also had a separate “user-agent: Googlebot” block. When Googlebot has its own section, Google reads only that section and skips the wildcard rules entirely. The more specific rule wins, every time.
To fix it: copy all shared rules into the Googlebot-specific section, or list every user-agent you want covered together before a single set of directives. Worth knowing too: robots.txt controls crawling, not indexing. Google can still index a URL it cannot crawl if other sites link to it. For Shopify, adding a noindex meta tag directly to search result templates is more reliable, which is what Shopify’s own documentation recommends. WordPress users with Yoast, Rank Math, or AIOSEO already have search pages set to noindex by default.

Technical SEO mechanics are shifting fast, but the bigger disruption may be at the model level: how Google decides what to surface and for whom is starting to look less like a search engine and more like a content platform.
➞ The TikTokification of Search: Why Creator Authority Is Replacing Domain Authority
Moz’s Mikael Araújo spent years at a creator-led company where marketing ran through influence, not traffic. He now sees Google building that same model. The evidence is already in production. Google Creator Profiles are live, public, and followable, pulling together a creator’s content from LinkedIn, X, YouTube, and Instagram into one indexed entity. Barry Schwartz, editor of Search Engine Roundtable, has over 670k followers on his Google Creator Profile. That is not a minor feature: authority is migrating from the domain to the individual.
AI Overviews now pull grounding content from social platforms directly, with lower-DA sources getting cited over authoritative domains when they answer a specific query better. Search sessions are getting longer too. Google’s own data shows follow-up queries climbing more than 40% month over month in the US, as AI Mode keeps users inside Google rather than sending them out to websites.

➞ What This All Means for Your Strategy
Read together, this week’s stories share a common thread: the things that look fine on the surface are changing underneath. LinkedIn reports look normal, but 40% of what people see is AI-generated. Robots.txt looks configured, but Google may be reading a different section of it.
Google Creator Profiles exist and are already indexed, but most marketers have not checked theirs. The CMO who turned Chrome from zero to the dominant browser did it by staying close to the user, not by chasing the tactic of the quarter. That still holds.
Until next week, Nishat from HighDegree* Marketing.
