How AI reads this site

The first words an assistant reads on its home page.

What an assistant reads first

Home pageWhat it says
TitleGrammar That - Simple Grammar
DescriptionSimple Grammar
First headingNone in the HTML
OpeningNone in the HTML

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

  2. Rewrite the description

    Its description is 14 characters, too few to choose a site by.

    Agent instructions

    On grammarthat.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. 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.
