What an assistant reads first

Home pageWhat it says
TitleSummit Materials | Pathways for a Brighter Tomorrow
DescriptionSummit Materials is a leading vertically integrated materials-based company that supplies aggregates, cement, ready-mix concrete and asphalt in the United States and British Columbia, Canada.
First headingPathwaysfor a brighter tomorrow.
OpeningAt Summit Materials, we are creating a positive impact in all the places we call home.

4 changes so it reads plainly as what it is

  1. Say what you do, for whom and where

    Its pages read as two kinds of work at once as Nonprofits and charities. An assistant matches a site to a question by what its pages plainly say.

    Agent instructions

    On summit-materials.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 Nonprofits and charities. Keep the title under 60 characters and lead with the service, not the name.

  2. Rewrite the description

    Its description is 191 characters and is cut off in results.

    Agent instructions

    On summit-materials.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 Denver in the first words

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

    Agent instructions

    On summit-materials.com, name Denver in the home page title or first sentence, and in the description, where it reads naturally.

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

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

    Agent instructions

    On summit-materials.com, find where the site mixes Nonprofits and charities with Manufacturers and suppliers, 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.
