Can you help me find the right word/s? [See details].

As a Yahoo! Store developer, I get lots of calls from existing store owners who either did it themselves to get started, using the Yahoo! cookie-cutter look, or who had their site done professionally a decade ago—and have seen sales decline as the site looks ever more dated and as the Google Panda algorithm downgraded the site’s search ranking.

I have a word .DOTX template for a makeover proposal. After talking through their needs, taste and budget; I fill it in with the particulars that suit them, and fire it off to them. The very first item in the deliverables list is what is troubling me. It reads:
    1.   Home page with hard-hitting text and graphics to sell SITENAME products.
The text in bold sounds lame and, well, dated like the sites it’s intended to update.

It needs to get across this point. Internet usage researchers have determined that users shopping on the Web form an opinion about whether a site that a search sends them to is it (has what they are looking for, is trustworthy, and worth exploring) or is not it in one-twentieth of a second. They will stay on a page longer than 50 milliseconds, but if that first instantaneous impression doesn’t convince them; they almost always back button to their original search and try another link.

I’m looking for a succinct way to say in my proposal that we understand this and will build them a site with a home page crafted to win that critical instant approval. Can anybody help me distill it down? Or should I first explain the one-twentieth of a second rule and then refer to that explanation in the deliverables list when describing the home page makeover?
