What an assistant reads first

Home pageWhat it says

First headingNone in the HTML
OpeningDid you take part in a successful record attempt?

4 changes so it reads plainly as what it is

  1. Say what you do, for whom and where

    Its pages read only partly as Agencies and studios. An assistant matches a site to a question by what its pages plainly say.

    Agent instructions

    On guinnessworldrecords.com, rewrite the home page title and its first sentence to say plainly what the business does, for whom and where, so the site reads as Agencies and studios. Keep the title under 60 characters and lead with the service, not the name.

  2. Make the first heading say what the title says

    The home page has no first heading in its HTML.

    Agent instructions

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

  3. 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 guinnessworldrecords.com, add JSON-LD to the home page declaring the most particular schema.org type for the business (one that fits Agencies and studios), with its name, address, phone and sameAs links to its own profiles.

  4. Give each kind of work a page of its own

    It reads close to Nonprofits and charities as well as Agencies and studios. Mixed on one page, neither reads plainly.

    Agent instructions

    On guinnessworldrecords.com, find where the site mixes Agencies and studios with Nonprofits and charities, and give each its own page, linked from the home page, so each page is about one thing.

  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.
