Sightline · product audits

What's wrong with your website, and the proof.

Sightline checks your live website and tells you, in plain words, what puts visitors off, what keeps you out of search and what in its setup needs tightening. Each problem comes with the proof we saw and the fix, so your team knows exactly what to change.

A hosted report and a PDF, with the evidence for every finding.

For site owners, agencies and portfolios.

Invite only until mid-November.

Example High Interface /contact

The contact form sends messages to an address that no longer exists.

Evidence: The form on /contact submits to /forms/contact.php, and that address answers "404 Not Found".
Why it matters: Visitors fill in the form, press Send and never hear back. Most won't try a second way to reach you.
Fix: Point the form at the address that receives your messages, then send yourself a test.

Evidence

/contact form: action="/forms/contact.php"GET /forms/contact.php: 404 Not Found

Fix for your developer

set the form action to the live handler, e.g. action="/api/contact"

Example finding.

Sightline · website analysis

An independent read of your live site: what works, what doesn't and the evidence for each.

Point Sightline at a URL. It reads the site across three lenses in a single pass, and returns a categorised report where every finding ships with the verbatim evidence behind it: the exact header, string or page, plus the fix.

Interface

UX, forms, accessibility

What we look at: Navigation, links and forms, layout on a phone, accessibility and claims that contradict each other, on the pages a visitor actually moves through.
What a visitor notices: A form that won't send, a button that's hard to find, text too small to read on a phone, a price that differs from one page to the next. Most people don't complain; they leave.
Usually fixed by: Your web designer or front-end developer, usually as layout and wording changes.

Search visibility

SEO, metadata, structured data

What we look at: Page titles, descriptions, headings, links, structured data and whether search engines can reach and read every page.
What a visitor notices: Your pages show up in search with a missing or wrong title, a blank description or not at all.
Usually fixed by: Whoever edits the site's content, sometimes with a developer for the structured data.

Technical

headers, cookies, HTTPS

What we look at: Security headers, cookies, the HTTPS certificate and what the site's responses give away. Read from what the site returns to any visitor.
What a visitor notices: Usually nothing at first. These are the gaps that make a browser warn, or make an account easier to take over.
Usually fixed by: Your developer or hosting provider, usually as a configuration change.

A Technical finding

Some fixes are for your developer. The finding still says in plain words what's wrong and why it matters, then gives the exact change to make.

What you get

Evidence on every finding: the verbatim string, header or page it came from, so nothing is a claim you have to take on faith.
A categorised report and a PDF: findings grouped by the area they concern and by severity, ready to hand to a team or a stakeholder.
Written for the owner: plain language for the team, the exact fix for the developer, method noted on every finding.

Example Medium Technical /checkout

Signed-in shoppers' sessions lack standard cookie protections.

Evidence: The checkout page sets its sign-in cookie without the three protections browsers look for.
Why it matters: One bad script on the page, or one visit over an unsafe connection, can be enough for someone else to act as that shopper.
Fix: A small settings change for your developer, shown below.

Evidence

/checkout response: Set-Cookie: sid=a1b2c3d4; Path=/

Fix for your developer

add Secure; HttpOnly; SameSite=Lax to the session cookie

Example finding.
