07 / FREQUENTLY ASKED QUESTIONS

Client Intent & FAQ Guide

Hiring a Developer

Look past the portfolio screenshots. Check for real, verifiable projects (live sites you can actually visit), a stack that matches your project (WordPress/WooCommerce vs. custom-coded), and evidence they handle what happens after launch — site speed, SEO, conversion tracking — not just design. A developer who also understands marketing will build something that performs, not just something that looks good.

For most small businesses, a specialized full-stack freelancer is faster to reach, costs less than agency overhead, and often covers more ground hands-on (development, SEO, DevOps, ads) than a single agency department. Agencies make more sense at larger scale or when you need a dedicated team across many channels at once.

Builders trade long-term flexibility for short-term speed — fine for a simple landing page, but slow and hard to optimize once you need an online store, custom features, or real SEO/ad tracking. A custom WordPress or PHP build costs more upfront but gives full control over performance, schema markup, and integrations that actually move rankings and conversions.

Building an Online Store

Conversion comes from three things working together: fast load times (Core Web Vitals), a frictionless checkout (single-page/AJAX instead of multi-step), and accurate conversion tracking so ad spend targets people who actually buy. A WooCommerce build with custom schema markup, page caching, and server-side conversion tracking typically outperforms an out-of-the-box store on all three.

It depends on catalog size and custom features, but a well-built WooCommerce store on optimized shared hosting — with custom checkout flows, schema markup, and server-side conversion tracking — typically runs 1–3 weeks of development. Get a scoped quote based on your product catalog and integrations rather than a flat number.

A standard WooCommerce build takes 1–3 weeks depending on feature complexity (custom checkout, product variants, payment gateways). Adding server-side conversion tracking (CAPI) for Meta, Google, and TikTok is usually a 1–2 day add-on once the store itself is live.

SEO & Site Performance

Beyond keywords, real SEO work covers technical audits (site speed, crawlability, mobile usability), on-page optimization (schema markup, content structure), and off-page authority building. A 90+ PageSpeed score and clean JSON-LD schema are two concrete signs it's being done right — not vague promises.

Common causes are bloated themes/plugins, unoptimized images, no caching layer, and poorly configured shared hosting. Most WordPress/WooCommerce speed issues can be fixed within 3–5 business days through caching, image optimization, and hosting-level tuning — without migrating off shared hosting or rebuilding the site from scratch.

Technical fixes (site speed, schema, crawl errors) can show up in Search Console within days to a few weeks. Ranking improvements for competitive keywords typically take 2–4 months of consistent on-page and content work — anyone promising overnight #1 rankings isn't describing real SEO.

Ad Tracking & Lead Generation

Browser-based tracking (the Meta Pixel alone) loses a large share of conversion events to ad blockers, Safari's ITP restrictions, and cookie consent blocking — often 25–40%. Server-side conversion tracking (CAPI) sends events directly from your server instead of the browser, recovering most of that lost attribution.

CAPI sends purchase/lead events from your server directly to Meta, Google, and TikTok instead of relying only on browser-side pixels, which ad blockers and Safari increasingly block. If you're running paid ads on a WooCommerce or WordPress site, it's close to mandatory now — the difference between optimizing campaigns on real data or on a partial sample of it.

Lead quality comes from accurate audience targeting (custom/lookalike audiences built on clean pixel + CAPI data), tight ad creative testing, and continuous A/B optimization based on real conversion data rather than platform estimates. Fixing your tracking setup before scaling ad spend is usually the highest-leverage first step.

SaaS & Software Licensing

You need a licensing backend that can issue, validate, and revoke keys in real time via a REST API, a client dashboard for subscription management, and webhook-based automation for renewals and access control. This runs efficiently on PHP/MySQL even on shared hosting — it doesn't require expensive cloud infrastructure to start.

Portfolio & Developer Selection

Look for someone who treats your site like a product, not just a design exercise — it should load fast, use clean schema markup, and be structured for search visibility from day one. A developer who also understands SEO and conversion tracking makes different build decisions than one who only cares about visuals.
