Anything we couldn’t read is its own segment — a page that blocks our reader is our limitation, not a mark against you, and it never lowers your score.

Priorities

Fix these first

Ranked by revenue impact. Each one is something beginners — or an AI answer engine — need to see and currently can't. Fixing the top few moves your score the most.

01

Search engines can’t tell what you sell

Add structured data (LocalBusiness / Organization schema: address, hours, phone, ratings) so search engines show you with rich results.

02

No price anywhere on the page

Add explicit 'Free to start. No credit card. No subscription.' directly under the primary CTA to eliminate signup hesitation.

03

AI assistants have nothing to read

Publish /llms.txt with a concise machine-readable product summary, audience, pricing, and docs links.

What we read on your page

What a customer finds — and doesn’t

3 of the 8 things we could check are already on your page. We found only 3 of the 8 things a customer looks for before they act. Most visitors are leaving without enough reason to call, book or buy.

Below is the breakdown: what's already working (with the exact text quoted from your page as proof), and the highest-impact additions to win more software downloads — in priority order.

Scope: an automated scan of the 2 pages we could read across your site. Every “found” item quotes the exact text on your page so you can verify it. It doesn't judge copy quality or design.

Already on your page

  • A headline that says what you do — found: “Learn piano the easy way”
  • An obvious button that starts the thing — found: “Download for Windows”
  • An easy way to get in touch — found: “form field on page”

What to add, in order of impact

  • Reviews or proof from real customers — Add a testimonial, customer logo, star rating, or an 'N customers' proof point near the top.
  • A concrete number, not an adjective — Add a concrete number (result %, time saved, customers served). Specifics convert better than adjectives.
  • Something that removes the risk of trying you — Lower perceived risk: free trial, money-back guarantee, no credit card, or cancel-anytime.
  • A price, or at least a from-figure — Show pricing or a 'starting at' anchor so buyers can self-qualify without emailing.
  • Answers to the questions people ask before buying — Answer the top 3-5 buyer objections in an FAQ to remove hesitation before the CTA.

Deliverable

The full write-up

The full work-up for Lumikey — every fix, with copy and code ready to paste.

Complete fix plan (every issue, step by step)

1. Search engines can’t tell what you sell

Add structured data (LocalBusiness / Organization schema: address, hours, phone, ratings) so search engines show you with rich results.

  1. Add JSON-LD using the schema snippet below, edited with your real details.
  2. Validate it in Google's Rich Results Test before publishing.
  3. Keep it in sync with the on-page facts (name, address, phone, offers).

2. No price anywhere on the page

Add explicit 'Free to start. No credit card. No subscription.' directly under the primary CTA to eliminate signup hesitation.

  1. Show pricing, packages, or a 'from …' anchor so buyers can self-qualify.
  2. If pricing is bespoke, give a starting price or a typical range.
  3. Pair each price with what's included so it reads as value, not cost.

3. AI assistants have nothing to read

Publish /llms.txt with a concise machine-readable product summary, audience, pricing, and docs links.

  1. Publish /llms.txt with a plain-text product summary, audience, pricing and key links.
  2. Keep it concise — answer engines reward clear, factual structure.
  3. Update it when your offer or pricing changes.

Why it matters

The fastest beginners do not read every page. They scan the first screen, trust signals, pricing cues and how easy it is to download the app. Missing signals make the offer harder to understand and easier to ignore.
