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 developers — 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

Include pricing information or a clear signal about the value of Protobuf.

03

No easy way to get in touch

Ensure there is a clear path for users to get support or more information.

04

AI assistants have nothing to read

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

05

Your page title doesn’t say what you do

Make the page title more descriptive to highlight Protobuf's benefits.

06

Search engines have no map of your site

Publish /sitemap.xml and submit it to search engines.

What we read on your page

What a customer finds — and doesn’t

4 of the 8 things we could check are already on your page. Your page has 4 of the 8 things a customer looks for. Adding the rest is the quickest way to get more out of the visitors you already have.

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 trial signups — in priority order.

Scope: an automated scan of the 5 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: “PROTOBUF EXPLAINED”
  • An obvious button that starts the thing — found: “Get Started”
  • Reviews or proof from real customers — found: “used by” (on /basics)
  • A concrete number, not an adjective — we found “01 M”, which points at it, but no actual number on the page we read (on /basics)

What to add, in order of impact

  • 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.
  • An easy way to get in touch — Give an easy capture path: short form, booking link, or contact route from the first screen.
  • 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 is ready

We've already done the full work-up for Protobuf.com, a visual, interactive guide to Protocol Buffers — every fix written out, with copy and code ready to paste. Here's what's inside:

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

Include pricing information or a clear signal about the value of Protobuf.

  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. No easy way to get in touch

Ensure there is a clear path for users to get support or more information.

  1. Add a visible booking link, short form, or tap-to-call number on the first screen.
  2. Keep the form to 3 fields max; every extra field drops completion.
  3. Confirm submissions with a clear success state, not a silent reload.

4. 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.

5. Your page title doesn’t say what you do

Make the page title more descriptive to highlight Protobuf's benefits.

  1. Write a 50–60 character <title> in the format: Primary outcome for [audience] — [Brand].
  2. Put the most-searched term first; keep the brand at the end.
  3. Make every important page's title unique — never reuse the homepage title.

6. Search engines have no map of your site

Publish /sitemap.xml and submit it to search engines.

  1. Publish /sitemap.xml listing every indexable URL with <lastmod>.
  2. Reference it from robots.txt and submit it in Google Search Console.
  3. Regenerate it automatically whenever pages change.

Why it matters

The fastest developers do not read every page. They scan the first screen, trust signals, pricing cues and how easy it is to start a free trial. Missing signals make the offer harder to understand and easier to ignore.
