How AI reads this site

The first words an assistant reads on its home page.

What an assistant reads first

Home pageWhat it says
TitleScott Aaronson
DescriptionNone in the HTML
First headingNone in the HTML
OpeningI'm Schlumberger Centennial Chair of Computer Science at The University of Texas at Austin, and director of its Quantum Information Center. My research interests center around the capabilities and limits of quantum computers, and computational complexity theory more generally.

4 changes so it reads plainly as what it is

  1. Make the first heading say what the title says

    The home page has no first heading in its HTML.

    Agent instructions

    On scottaaronson.com, give the home page one first heading (h1) that says, in a reader's words, what its title says the site is.

  2. Write a description

    The home page has no description, so a search result and an assistant make one up from the page.

    Agent instructions

    On scottaaronson.com, write the home page a meta description of one or two sentences, 50 to 160 characters: what the business does, for whom, and where.

  3. Name Concord in the first words

    The site is in Concord, and its title, description, first heading and opening never say so. Questions to assistants often name a place.

    Agent instructions

    On scottaaronson.com, name Concord in the home page title or first sentence, and in the description, where it reads naturally.

  4. Say what kind of business it is in structured data

    Its home page declares no business or organization type, so a machine has to guess what it is.

    Agent instructions

    On scottaaronson.com, add JSON-LD to the home page declaring the most particular schema.org type for the business, with its name, address, phone and sameAs links to its own profiles.

  5. Read it again

    mttr reads the site again and says how it reads now.

An estimate made by mttr against 16 lines of work, from its home page before any script runs. It is not what any assistant says about the site. Rethink the direction with us.
