Finding a web agency is easy. Finding one that delivers — on time, on budget, with results you can measure — is harder than it should be.
The industry is full of agencies with polished portfolios, confident sales calls, and a habit of overpromising. After building dozens of business websites, we've seen what separates good agency relationships from expensive mistakes.
These 7 questions cut through the noise. Ask every agency you shortlist. The answers will tell you more than any proposal.
1. Can I See Live Examples of Sites You've Built?
Every agency has a portfolio page. Not every portfolio links to real, live websites. Ask for URLs you can actually visit and test.
Open the sites on your phone. Run them through Google's PageSpeed Insights. Check if they load in under 2 seconds. Look at the mobile experience. A beautiful screenshot means nothing if the real site is slow.
Red flag: Agencies that show only mockups, screenshots, or Dribbble images — not live URLs.
2. Who Actually Builds My Website?
Many agencies sell the work, then outsource the execution. You get sold by a senior account manager and handed to a junior freelancer in a different timezone.
Ask directly: who will be doing the design, the development, and the quality control? Are they employees or contractors? Will you have a single point of contact throughout the project?
Red flag: Vague answers like "our development team" or "we work with vetted partners." These are often outsourcing euphemisms.
3. What Technology Do You Build On, and Why?
Technology choice shapes your website's performance, security, and future costs. A good agency will explain their stack and the reasons behind it — not just use whatever is cheapest or most familiar.
Ask: Do you use WordPress, Webflow, a custom framework? What are the trade-offs? Who maintains it after launch?
| Answer | What it means |
|---|---|
| WordPress | Flexible, widely supported. High maintenance overhead — frequent plugin updates, security vulnerabilities. |
| Webflow | Fast to design. Limited customisation ceiling, monthly SaaS cost, no code ownership. |
| Custom React / Next.js | Best performance and flexibility. Higher initial investment, developer required for changes. |
| "Whatever you prefer" | Red flag — no clear technical opinion means no technical accountability. |
4. How Do You Handle Content Changes After Launch?
This is where many business owners get stuck. The site goes live, and then they discover that every text change requires emailing the agency, waiting for a quote, and paying a developer hourly.
Ask specifically: what does the post-launch editing process look like? Is there a CMS? What's included in the retainer? What gets charged separately?
What good looks like: A clearly defined process for routine changes, transparent pricing, and either a self-service CMS or a retainer with predictable costs.
5. What Does Your Launch Timeline Look Like?
"We'll have it done in 4–6 weeks" is almost always optimistic by week three. Not because agencies are dishonest — because projects expand, feedback rounds take longer than expected, and agencies juggle multiple clients simultaneously.
Ask for a milestone-based timeline: when will you see the first wireframes? First design? First staging site? What happens if a feedback deadline slips?
What good looks like: A specific, milestone-based schedule with clear ownership at each stage. Agencies that have built enough sites have templates for this.
6. What Happens If I'm Not Happy With the Result?
Almost no one asks this before signing. It's one of the most important questions.
Ask: How many revision rounds are included? What's the process if the design direction isn't right? Is there a satisfaction clause in the contract?
What good looks like: A defined revision process, a contract that specifies deliverables clearly, and an agency that has thought through how disagreements get resolved.
7. How Do You Measure Success?
A website is not a deliverable — it's a business tool. An agency that considers their job done at launch has missed the point.
Ask: How will we know if the site is performing well? Do you track Core Web Vitals, conversion rates, organic traffic? Will you share performance reports after launch?
What good looks like: The agency talks about metrics. They have opinions on what success looks like for your specific business. They track results, not just aesthetics.
The Shortlist Scorecard
After your conversations, score each agency on these criteria:
| Criterion | What you're checking |
|---|---|
| Portfolio | Live URLs, mobile speed, relevance to your industry |
| Team transparency | Clear who builds and manages — no outsourcing surprises |
| Technology choice | Justified decision, not just convenience |
| Post-launch process | Editing clarity, retainer or CMS, transparent pricing |
| Timeline rigour | Milestone-based, not just a single deadline |
| Revision clarity | Process defined in contract before you sign |
| Metrics orientation | They talk about performance, not only design |
The Red Flags Worth Repeating
- No pricing on their website — you're always priced as the most expensive sale
- Generic, copy-paste proposals that don't reference your business, your competitors, or your goals
- Promises of first-page Google rankings by a specific date
- Contracts vague about what "a website" includes
- They can't explain why they use the technology they use
