Google preview showing outdated pages

Hello,

I am a beginner at Hugo and I managed to create and deployed my academic website.
Here is my repository: GitHub - valentinaruts/starter-hugo-academic
My issue is that when I google “Valentina Rutigliano” in incognito the google preview shows some outdated links that are part of the default Hugo Academic but I eliminated from my repository because I don’t need them, e.g. “Example Talk”, as shown in the screenshot.


What I tried: following online advice, I tried to add a robot.txt file under the static folder to disallow those files. I also unlinked and relinked the repository on Netlify and cleared cache before deploying. However, when I look at “Deploy file browser” on Netlify, I can still see the outdated files such as publication_types.
Related to this, the google preview also shows an outdated icon which is not even in my repository anymore.
I’m sure this is a very beginner issue but I’m trying to learn and I’m out of ideas on how to fix it.
Thanks!

1stly, nothing to do with Hugo.

2ndly, you don’t have control over how Google will display your site in search what preview will be there, and which pages will be picked.

Head to Google Search Console and re-index your site. Refresh sitemaps (check if sitemaps show correct pages) etc.

This is a general WebDev matter. Plenty of help is available over the internet.

ps.
as a hint, when looking into your netlify.toml file, you are building your website still with HUGO_VERSION = "0.97.3".
