The redesigned Images homepage is a browseable gallery of images from across the web that updates in real time, tailored to your interests when you’re signed in, with saved collections appearing as tabs above the gallery. Both roll out over the coming weeks.\n\n### Why This Matters\n\nAI Overviews already answer plenty of queries without a click. Generated images give that surface one more thing it can produce on its own, in a spot that has pointed people toward images from the web. The redesigned homepage adds a starting point that isn’t a query at all, a personalized feed sitting alongside the search box.\n\nRead our full coverage: [Google Adds Image Generation To AI Overviews, Revamps Images](https://www.searchenginejournal.com/google-adds-image-generation-to-ai-overviews-revamps-images/582242/)\n\n## Mueller Answers A Plan To Hide A Homepage Link\n\nGoogle Search Advocate John Mueller responded to a plan to stop a homepage button from being a link, so a better-worded link further down the page would count instead. He suspects the person behind it is overthinking it.\n\n**Key facts:**\n\nThe [r/bigseo thread](https://www.reddit.com/r/bigseo/comments/1uwb1el/comment/oxi1l3t/) describes a homepage that links to the same services page twice: once via a Services button near the top and once via an FAQ link worded the way the poster wants Google to read it. The plan was to make the button stop being a link while it still worked when clicked, leaving the FAQ link as the only regular link pointing there. Mueller said he wouldn’t expect to see any visible change, and suggested using CSS or JavaScript to position things on the page instead.\n\n### Why This Matters\n\nInternal anchor text has been an optimization technique for years, which is why a plan like this sounds reasonable. What it costs is a homepage whose main button is no longer a link. What it buys, by Mueller’s reading, is nothing you could measure. His alternative keeps both links and moves only their order in the code.\n\nRead our full coverage: [Google’s Mueller On First Link Priority & Link Obfuscation](https://www.searchenginejournal.com/googles-mueller-on-first-link-priority-link-obfuscation/582316/)\n\n## Mueller On Long A/B Tests\n\nSEJ’s Roger Montti looked at Mueller’s answer on A/B tests that run for six to twelve months and found that it seems to contradict Google’s own written guidance.\n\n**Key facts:**\n\nAsked on Bluesky how Google handles long-term holdouts on a marketplace with tens of millions of pages, Mueller said that, depending on the setup, one version or the other is used for indexing, and that variants sufficiently different from each other could appear in search results. Pressed on whether constantly changing HTML could get pages dropped, he said that, as far as he knows, there’s no penalty or demotion for having varying content, though it can make the content harder to debug and monitor if it changes constantly.\n\n### Why This Matters\n\nMontti’s read is that Mueller answered the indexing question twice, and that the question actually asked, about tests running most of a year, went untouched both times. That leaves a Googler’s reply and Google’s own documentation pointing different directions, and only one of the two is published guidance. The guidance is also the more specific of the two, warning against running an experiment longer than necessary, especially when one variant reaches a large percentage of users.\n\nRead our full coverage: [Google Says No SEO Penalty For Year-Long A/B Tests?](https://www.searchenginejournal.com/google-says-no-seo-penalty-for-year-long-a-b-tests/582349/)\n\n## Google Says Content-Based Canonical Fixes Can Take Two Weeks\n\nGoogle added a section to its canonicalization troubleshooting guide setting expectations for how long a content fix takes to show up in Search.\n\n**Key facts:**\n\nThe guide says pages may stay in a duplicate cluster for up to two weeks after you fix the content, and that they can split out faster when the new content is more distinct from the rest of the cluster. Google groups pages it reads as having the same or very similar main content, then selects one as the canonical. The two-week window covers content fixes rather than redirects, a rel=”canonical” correction, or a server misconfiguration, which the guide lists as separate issues.\n\n### Why This Matters\n\nThe number gives you something to say to a client asking why the fix hasn’t landed yet, and it scopes the wait to content changes rather than to every canonical problem. Two weeks is the outside edge, not the standard wait. Whether Google comes around to your preference by the end of it is a separate question.\n\nRead our full coverage: [Google Says Canonical Re-Evaluation Can Take Up to Two Weeks](https://www.searchenginejournal.com/google-says-canonical-re-evaluation-can-take-up-to-two-weeks/582053/)\n\n## Theme Of The Week: You Get A Vote, Not A Veto\n\nThree of this week’s four stories land on the same thing. You supply an input, and Google keeps the final say over how it gets read.\n\nThe canonicalization guide’s starting position is that Google’s pick might be the better one, and it asks you to weigh that before you troubleshoot anything. Mueller’s answer on the homepage button came down to a change he wouldn’t expect anyone to see. His answer on A/B tests was that one version or the other may be used for indexing, depending on how the test is set up.\n\nThe Images announcement sits beside that rather than inside it. It’s a product change, not a statement about how Google reads your pages. It points the same way, though, since generated images give Search one more thing it can make internally alongside what it finds on the web.\n\nThe lever you still hold is the quality of what you provide. Pages can split out of a duplicate cluster faster when the content is clearly different, and proper `<a href>`\n\nelements give Google links it can crawl. Google still decides what to do with both.\n\n**Top Stories Of The Week:**\n\n[Google Adds Image Generation To AI Overviews, Revamps Images](https://www.searchenginejournal.com/google-adds-image-generation-to-ai-overviews-revamps-images/582242/)[Google’s Mueller On First Link Priority & Link Obfuscation](https://www.searchenginejournal.com/googles-mueller-on-first-link-priority-link-obfuscation/582316/)[Google Says No SEO Penalty For Year-Long A/B Tests?](https://www.searchenginejournal.com/google-says-no-seo-penalty-for-year-long-a-b-tests/582349/)[Google Says Canonical Re-Evaluation Can Take Up to Two Weeks](https://www.searchenginejournal.com/google-says-canonical-re-evaluation-can-take-up-to-two-weeks/582053/)\n\n**More Resources:**\n\n[Google Says It Can Handle Multiple URLs To The Same Content](https://www.searchenginejournal.com/google-says-it-can-handle-multiple-urls-to-the-same-content/571424/)[Google Updates JavaScript SEO Docs With Canonical Advice](https://www.searchenginejournal.com/google-updates-javascript-seo-docs-with-canonical-advice/563545/)[Chrome Updated With 3 AI Features, Including Nano Banana](https://www.searchenginejournal.com/chrome-updated-with-3-ai-features-including-nano-banana/566134/)\n\n*Featured Image: PeopleImages/Shutterstock*", "url": "https://wpnews.pro/news/google-on-canonical-fixes-mueller-on-hidden-links-and-a-b-tests-seo-pulse", "canonical_source": "https://www.searchenginejournal.com/seo-pulse-google-on-canonical-fixes-mueller-on-hidden-links/582671/", "published_at": "2026-07-17 12:30:33+00:00", "updated_at": "2026-07-17 12:36:24.159196+00:00", "lang": "en", "topics": ["generative-ai", "ai-products", "ai-tools"], "entities": ["Google", "John Mueller", "AI Overviews", "Google Images", "Nano Banana"], "alternates": {"html": "https://wpnews.pro/news/google-on-canonical-fixes-mueller-on-hidden-links-and-a-b-tests-seo-pulse", "markdown": "https://wpnews.pro/news/google-on-canonical-fixes-mueller-on-hidden-links-and-a-b-tests-seo-pulse.md", "text": "https://wpnews.pro/news/google-on-canonical-fixes-mueller-on-hidden-links-and-a-b-tests-seo-pulse.txt", "jsonld": "https://wpnews.pro/news/google-on-canonical-fixes-mueller-on-hidden-links-and-a-b-tests-seo-pulse.jsonld"}}
