How AI reads this site

The first words an assistant reads on its home page.

What an assistant reads first

Home pageWhat it says
TitleInternational Space Station National Laboratory
DescriptionExplore the latest advancements in International space station research and discover how it impacts scientific progress.
First headingNone in the HTML
OpeningMore than two dozen ISS National Lab-sponsored investigations launched aboard NASA’s SpaceX CRS-35 mission, carrying research...

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

  2. Name Palm Beach Gardens in the first words

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

    Agent instructions

    On issnationallab.org, name Palm Beach Gardens in the home page title or first sentence, and in the description, where it reads naturally.

  3. 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.
