Post Date Often Included in Google Search Title Links

Earlier this year, I noticed that when I googled the titles of some of your posts, the date was included in the title link: <details> <summary>Example</summary> <p> <img width="2077" height="870" alt="Image" src="https://github.com/user-attachments/assets/35549b88-85eb-49bf-8531-8a9abf525426" /> </p> </details> The issue is likely caused by the fact that the date is contained within the `h1` tag: ```html <main> <article> <h1> Effective Pull Requests <time class="meta" datetime="2018-05-03">May 3, 2018</time> </h1> .... </article> </main> ``` Looking at Google's [documentation](https://developers.google.com/search/docs/appearance/title-link#how-title-links-in-google-search-are-created), it does say that the contents of header tags are one of the sources used to create the title links. That still leaves the question of why some and not others, however. I tested all the posts and recorded the results in the table below. I don't see any patterns besides there being a solid run of unaffected posts near the beginning. <details> <summary>Results</summary> <p> | Post Title | Google Search URL | Title Link Contains Date? | |--------|--------|--------| font-size-adjust Is Useful | https://google.com/search?q=font-size-adjust+Is+Useful+site%3Amatklad.github.io | Not Found Inverse Triangle Inequality | https://google.com/search?q=Inverse+Triangle+Inequality+site%3Amatklad.github.io | Yes RSS Server Side Reader | https://google.com/search?q=RSS+Server+Side+Reader+site%3Amatklad.github.io | Yes Open Source Can't Coordinate | https://google.com/search?q=Open+Source+Can't+Coordinate+site%3Amatklad.github.io | Yes Profiling Challenge Results | https://google.com/search?q=Profiling+Challenge+Results+site%3Amatklad.github.io | No Scalar Select Anti-Pattern | https://google.com/search?q=Scalar+Select+Anti-Pattern+site%3Amatklad.github.io | Yes Performance Profile Visualization Challenge | https://google.com/search?q=Performance+Profile+Visualization+Challenge+site%3Amatklad.github.io | No Against Horizontal Scroll | https://google.com/search?q=Against+Horizontal+Scroll+site%3Amatklad.github.io | Yes A Fun Zig Program | https://google.com/search?q=A+Fun+Zig+Program+site%3Amatklad.github.io | No Things Zig comptime Won't Do | https://google.com/search?q=Things+Zig+comptime+Won't+Do+site%3Amatklad.github.io | No Underusing Snapshot Testing | https://google.com/search?q=Underusing+Snapshot+Testing+site%3Amatklad.github.io | No Random Numbers Included | https://google.com/search?q=Random+Numbers+Included+site%3Amatklad.github.io | Yes Tariffs | https://google.com/search?q=Tariffs+site%3Amatklad.github.io | No Deno Simple Server Side Rendering | https://google.com/search?q=Deno+Simple+Server+Side+Rendering+site%3Amatklad.github.io | Not Found A Debugger is a REPL is a Debugger | https://google.com/search?q=A+Debugger+is+a+REPL+is+a+Debugger+site%3Amatklad.github.io | Yes Use Long Options in Scripts | https://google.com/search?q=Use+Long+Options+in+Scripts+site%3Amatklad.github.io | No Comptime Zig ORM | https://google.com/search?q=Comptime+Zig+ORM+site%3Amatklad.github.io | Yes MacOS for KDE Users | https://google.com/search?q=MacOS+for+KDE+Users+site%3Amatklad.github.io | Yes What Is a dependency?

According to [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/header), because it would be nested inside a `main` tag, it would not have the `banner` role, and would be interpreted as just another `section`. ```html <main> <article> <header> <h1> Effective Pull Requests </h1> <time class="meta" datetime="2018-05-03">May 3, 2018</time> </header> .... </article> </main> ``` You would have to use some CSS to get the spacing between the title and date to stay the same, though.
