Hiring the wrong developer costs more than the project fee — it costs you months of delays, a site that breaks on every update, and a codebase nobody else can maintain. The difference between a good hire and a bad one usually comes down to the questions you ask before signing a contract. Here are the 9 questions that separate competent WordPress developers from the ones who will cost you twice: once to build it, and again to fix it.
Why These Questions Matter
WordPress is easy to start with and hard to build well. That low barrier to entry means the market is flooded with developers who can install a theme and configure plugins but can't write custom code, handle security, or build for performance. The questions below test for the skills that matter after launch — when updates break things, traffic spikes, or a security vulnerability is disclosed. For a detailed cost breakdown by project type, see our guide on .
在雇佣 WordPress 开发者之前要问的 9 个问题
1. Do You Build Custom Themes or Customize Existing Ones?
This is the most important question because it reveals their actual skill level. A developer who only customizes pre-built themes (Astra, Divi, Avada) using page builders is a different hire from one who codes custom themes from scratch. Neither is inherently wrong — but the project requirements should dictate the approach, and you need to know which one you're getting. If your project needs a unique design converted from Figma or XD, you need a developer who can write theme code, not one who drags widgets. Ask to see examples of both.
2. Can I See a Live Site You Built — Not Just a Screenshot?
Screenshots hide problems. A live site reveals everything: how fast it actually loads (test it in PageSpeed Insights while you're talking), whether it's responsive on mobile, how the navigation works in practice, and whether the code is clean under the hood. Open the browser inspector and look at the source — is it clean semantic HTML or a wall of bloated page-builder divs? A confident developer will share live URLs without hesitation.
3. How Do You Handle WordPress Security?
If the answer is "I install Wordfence" and nothing else, that's a red flag. Security is layered: it includes security headers, login protection, file permissions, and monitoring. A good developer should be able to explain their hardening process without prompting. Ask specifically about brute-force protection, wp-config.php security, and what happens if a vulnerability is discovered in a plugin they installed.
4. What's Your Approach to Site Speed and Core Web Vitals?
Speed isn't something you bolt on after launch — it's an architectural decision made during development. Ask how they handle image optimization (do they use WebP?), render-blocking scripts (do they defer or async?), and caching strategy. A developer who can name LCP, INP, and CLS and explain how they optimize for each is someone who builds for performance, not someone who installs a caching plugin and hopes for the best. See how we approach this in our WordPress speed optimization services.
5. Do You Follow WordPress Coding Standards?
WordPress has official coding standards for PHP, HTML, CSS, and JavaScript. Following them means the code is readable, maintainable, and compatible with future WordPress updates. A developer who doesn't follow standards is building technical debt into your site — the kind that surfaces six months later when a core update breaks everything and nobody can figure out why.
6. How Do You Handle Staging and Testing Before Launch?
If a developer builds directly on your live server, walk away. Professional WordPress development uses a staging environment — a private copy of the site where changes are built and tested before being pushed live. Ask about their deployment process: do they use staging? How do they handle database migrations? What's their rollback plan if something breaks? "I'll be careful" is not a deployment strategy.
7. What Happens After Launch — Do You Offer Maintenance?
A WordPress site needs ongoing updates, security monitoring, and occasional fixes. If the developer disappears after launch, you're on your own when a plugin conflicts with a core update or a security patch needs testing. Ask whether they offer ongoing maintenance and care plans, what they include, and what the response time is for urgent issues.
8. How Will My Site Appear in Google Search Console?
This question tests whether the developer thinks about SEO at all. A surprising number don't. Ask about their approach to: meta titles and descriptions, heading structure (proper H1/H2 hierarchy), schema markup, XML sitemaps, and robots.txt configuration. A developer who sets up Google Search Console and walks you through it during handover is one who understands that a site exists to be found, not just to look nice.
9. What Does Your Handover and Documentation Look Like?
When the project ends, you should receive: all login credentials and hosting access, a documented list of installed plugins and their purpose, a training session or video walkthrough, and ideally a brief technical document covering custom code and configurations. If the developer can't describe their handover process, you risk being locked into a dependency where only they can maintain your site — which gives them leverage and leaves you vulnerable.
Red Flags to Walk Away From
They can't show a live site they've built (only screenshots or Behance mockups)
They quote a price without asking about your requirements first
They build directly on your live server with no staging
They can't explain their security practices beyond "I install a plugin"
They don't mention SEO, speed, or Core Web Vitals at any point
They use nulled or pirated plugins to save costs
Frequently Asked Questions
How much should I expect to pay a WordPress developer?
It depends on project scope. A simple business site, a WooCommerce store, and a complex membership platform have very different requirements and budgets. We break down the ranges by project type in our WordPress development cost guide. Get a fixed-scope quote before work begins so there are no hourly surprises.
Should I hire a freelancer or an agency?
Freelancers are typically less expensive and work well for straightforward builds. Agencies bring broader skill sets (design, development, SEO, security), accountability, and continuity — if your main contact leaves, the project doesn't stop. For mission-critical sites or those needing ongoing maintenance, an agency is usually the safer investment.
How long does a typical WordPress project take?
Most business websites take 4–8 weeks from kickoff to launch. Complex builds with e-commerce, membership systems, or large-scale data migration can take 8–12 weeks. Be wary of developers who promise a full custom site in under two weeks — speed at that pace usually means shortcuts.
What should I prepare before hiring?
A clear brief helps both sides: your goals for the site, 3–5 competitor or inspiration sites, a rough sitemap (which pages you need), your content (or a plan to create it), branding assets (logo, colors, fonts), and your timeline. The more defined your brief, the more accurate the quote and the smoother the build.
概括
Before hiring a WordPress developer, ask about custom vs. template builds, request live site URLs, test their security and speed knowledge, confirm they use staging environments and follow WordPress coding standards, ask about post-launch maintenance, verify they think about SEO, and get clarity on handover documentation. These nine questions expose whether you're hiring someone who builds sites that last — or someone who assembles templates that break.
