How AI reads this site

The first words an assistant reads on its home page.

What an assistant reads first

Home pageWhat it says
TitleCSHL DNA Learning Center
DescriptionNone in the HTML
First headingField Trips at a DNALC Near You
OpeningTeacher professional development in genetics and biotechnology

4 changes so it reads plainly as what it is

  1. Make the first heading say what the title says

    The title and the first heading share no word that says what the site does: “CSHL DNA Learning Center” and “Field Trips at a DNALC Near You”.

    Agent instructions

    On dnalc.org, 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 dnalc.org, 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 Cold Spring Harbor in the first words

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

    Agent instructions

    On dnalc.org, name Cold Spring Harbor 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 dnalc.org, 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.
