Guide: AI-Powered UX Audit vs. Competitors

A UX audit used to mean hiring an agency, waiting weeks for a report, and spending thousands of dollars before you had a single actionable insight. AI tools have fundamentally changed that timeline. You can now run a structured, multi-site UX audit in a single session — comparing your site against three competitors simultaneously — and walk away with a prioritized roadmap the same afternoon.

This guide walks through using Gemini 3 (or a comparable reasoning-capable model) to conduct a professional UX audit. The output includes a competitive matrix, a SWOT analysis, friction point analysis, and a quick-win roadmap — all from one prompt.

What You'll Need

AI Access: Gemini 3 Pro or Ultra (with Deepthink/Reasoning Mode enabled). GPT-5 or Claude also work.

Your Assets: URLs for your site and three competitors. Full-page screenshots of your mobile homepage and checkout/contact page (JPEG or PNG).

Your Context: A defined target persona (e.g., "budget-conscious small business owner") and your site's primary conversion goal (e.g., "sign up for a free trial").

Step 1: Prepare Your Screenshots

NOTE: You can still get lots of insight with simply including the URLs, without screenshots. That said, with screenshots, you get even more insight and context.

Before running the prompt, take full-page screenshots of your website.

Why it matters: Gemini 3 is highly visual. While the model can browse live URLs, real sites often have pop-ups, cookie banners, and paywalls that block AI crawlers. Screenshots eliminate that problem and give the model a clean, complete view of what your visitors actually see.

Capture two views at minimum:

• Your mobile homepage (what a visitor sees first on a phone)

• Your checkout or main conversion page (where the decision happens)

Attach both images directly to the prompt in your next step.

Step 2: Run the UX Master Audit Prompt

Copy the prompt below. Fill in the bracketed fields — your industry, URLs, target persona, and primary conversion goal — then attach your screenshots before sending.

Role: You are acting as a Senior UX Strategist and Conversion Rate Optimization
(CRO) Expert with 15 years of experience in [Your Industry, e.g., B2B SaaS /
Luxury E-commerce].

Task: Conduct a deep-dive UX audit and competitive benchmarking analysis for my
website and three primary competitors.

Websites to Analyze:
1. My Site: [Insert URL]
2. Competitor A: [Insert URL]
3. Competitor B: [Insert URL]
4. Competitor C: [Insert URL]

Core Objective: Identify why users might choose a competitor over me and provide
a prioritized 90-day roadmap to make my site the market leader in usability and
conversion.

Instructions for Analysis:
1. Heuristic Evaluation: Evaluate all four sites based on Nielsen's 10 Usability
   Heuristics. Focus specifically on "Consistency and Standards" and "Aesthetic
   and Minimalist Design."

2. User Journey Mapping: Simulate the journey of a [Target Persona, e.g.,
   "Budget-conscious small business owner"] looking to [Primary Goal, e.g.,
   "Sign up for a free trial"]. Point out specific friction points on my site vs.
   the "happy path" on competitor sites.

3. Visual & Accessibility Check: Compare the visual hierarchy, use of whitespace,
   and mobile responsiveness. (Note: I have attached screenshots of my mobile
   homepage and checkout for better "vision" analysis).

4. Value Proposition Audit: Analyze the "Above the Fold" content. Is my UVP
   (Unique Value Proposition) clearer or weaker than the competitors?

Output Format:
* Competitive Matrix: A table comparing the 4 sites across 5 key UX metrics
  (Speed, Clarity, Trust Signals, Mobile UX, and Ease of Conversion).
* SWOT Analysis: A brief SWOT for my site specifically.
* The "Top 3 Friction Killers": Identify the 3 biggest things stopping my users
  from converting right now.
* Actionable Roadmap: A list of "Low Effort / High Impact" fixes I can implement
  this week.

Step 3: Interpret the Output

The prompt is structured to return four distinct deliverables.

Competitive Matrix — A table scoring all four sites across Speed, Clarity, Trust Signals, Mobile UX, and Ease of Conversion. Use it to spot where you're leading and where you're falling behind.

SWOT Analysis — A Strengths, Weaknesses, Opportunities, and Threats breakdown for your site only. This is useful for communicating priorities to stakeholders — it frames UX improvements in business terms, not just design feedback.

Top 3 Friction Killers — The three most significant barriers preventing users from converting, ranked by severity based on the AI's simulation of your target persona's journey. Focus on these before anything else.

Actionable Roadmap — A Low Effort / High Impact fix list you can begin implementing this week. Expect items like clarifying your above-the-fold headline, improving button contrast, or restructuring your mobile navigation.

Refinement Tip: The Cynical User Follow-Up

Once you have the initial report, send this follow-up to push the AI past polite observations into genuinely critical feedback:

"Now, act as a cynical user who is in a hurry. What is the one thing on my
homepage that would make you close the tab immediately?"

This single follow-up often surfaces the one insight the structured audit missed — usually something so obvious it was overlooked, but immediately recognizable once named.
