Website QA Checklist for Agencies Before Client Handoff

Agency website builds get judged on the final pass. A client who finds a typo in the hero, a stale year in the footer, or an inconsistent button label on the day of handoff will remember that more than any of the work that came before it. A repeatable QA checklist removes those moments from the process.

The checklist below is structured around the agency workflow: a single reviewer runs it on the staging URL, captures findings on the rendered page, and hands the client a clean punch list with screenshots attached.

Why a Dedicated QA Pass Matters Before Handoff

By the time a site reaches handoff, the team that built it has read the copy many times. Familiarity hides issues. The page that read perfectly in week three of a build will reveal three or four small problems on a fresh review in week six.

A separate QA pass, ideally done by someone who did not write the original copy, catches the issues that the build team has stopped seeing. Charging it into the project plan as a named step also gives the agency a clear artifact to deliver alongside the build.

Pre-QA: Confirm the Scope

Before touching the site, confirm:

• the canonical staging or production URL list, in priority order
• which pages are in scope and which are not
• which CMS or framework the client will own after handoff
• whether the client expects a single QA report or per-page reports
• which issues block sign-off and which are nice-to-have

A QA pass without an explicit scope tends to expand into a redesign. Pin the scope in writing before the review starts.

Page-by-Page Visible Copy Review

Open each in-scope URL and read the page top to bottom on the rendered version. For every page, check:

• hero headline and subheadline read as a clear promise, not a category
• primary and secondary calls to action use consistent labels
• pricing and package descriptions match what the client signed off on
• form labels, placeholder text, and error states are written in the brand voice, not framework defaults
• footer links resolve and point to the right destinations
• repeated components (cards, banners, testimonials) follow the same pattern on every page they appear

Flag anything that is technically correct but vague. "Streamline your workflow" copy in a hero is not a typo, but it is a handoff issue.

Trust-Critical Pages Need Extra Attention

Some pages carry more weight than others. Spend more time on:

• homepage hero and proof block
• pricing page and any plan comparison table
• contact and demo request flows
• legal pages (privacy, terms, cookies)
• security and trust pages, if present
• 404 and other error pages a client will not think to check

Mistakes in these areas reach buyers near the moment of decision. They are also the pages clients most often forward internally for review, which means issues here are the most visible after handoff.

Cross-Page Consistency Sweep

After the page-by-page pass, do a sweep that only looks at consistency across the site:

• product or feature names spelled the same way everywhere
• pricing numbers, plan names, and currency formats match across home, pricing, and any feature pages
• capitalization rules applied consistently to buttons, nav items, and section headings
• voice and tone do not drift between pages written by different team members
• legal entity name, address, and contact details match the footer on every page

Inconsistency is the kind of issue clients spot quickly because they read every page through the lens of their own brand standards. A consistency sweep catches issues that a per-page review misses by design.

Visual Regression and Layout Check

Copy QA on agency builds overlaps with layout QA, because copy length is the single biggest cause of layout drift. Check:

• hero and section headlines do not break awkwardly on common viewports
• buttons fit their labels without truncation in any locale the site supports
• cards and grids do not collapse or overflow when copy length varies
• images and screenshots are not stretched, compressed, or replaced with placeholders
• responsive breakpoints work on a real phone, not only the browser inspector

Capture a screenshot of any layout issue you find. A screenshot is faster for the client to act on than a written description.

Handoff Document Template

The QA report should be a short artifact a client can scan in five minutes:

• summary line: how many issues, how many blocking, how many cosmetic
• one section per page, with each issue on a single line and a screenshot
• a separate section for cross-page consistency findings
• a recommended order for resolving the issues
• a note on which issues, if any, are intentional and approved

Keep editorial commentary out of the report. The client wants a punch list, not a critique of the brand they signed off on three weeks ago.

Run the Final Pass on the Rendered Site

QA done in a CMS, a doc, or a design file misses the issues that only show up on the live render. Always run the final pass on the staging or production URL the client will see.

ProofScout is built for that pass. Submit the URL, get a screenshot-backed copy report, and attach those screenshots directly to the handoff document. It shortens the review cycle, gives the client a clearer artifact, and prevents the kind of late-stage typo a client never forgets.
