WordPress runs roughly 40% of the web — and it's the right tool for some businesses. For most small businesses, it's overkill, slow, and expensive to maintain. Here's the honest comparison so you can decide which fits your situation.
Custom-coded PHP websites ship a fraction of the code WordPress requires, score perfect on Core Web Vitals out of the box, and don't need 47 plugins to do what WordPress users assume is normal. WordPress wins when you publish dozens of blog posts a month or need a large editorial team. Custom wins for small business marketing sites where speed, security, and AI-search visibility actually matter.
| Dimension | WordPress | Custom-coded by Suncoast Local |
|---|---|---|
| Average page weight (KB) | 2,000–5,000 KB | 50–300 KB |
| Typical Lighthouse score | 40–70 (mobile) | 95–100 (mobile) |
| Plugins required | 15–50 typical | 0 — features built into the code |
| Plugin update frequency | Weekly, sometimes daily | Never — no plugins |
| Common attack surface | Plugins, themes, core | Tiny — only what you actually use |
| Hosting requirements | PHP + MySQL + caching | PHP + MySQL (or static) |
| Schema markup | Plugin-dependent, partial | Full linked graph, ships by default |
| AI search readiness (GEO) | Depends entirely on plugins | Built in: llms.txt, entity schema, IndexNow |
| Editing for non-developers | Built-in WP admin (Gutenberg) | Custom admin tuned to your specific content |
| Customization ceiling | Limited by theme + plugin compatibility | No ceiling — code does exactly what you need |
| Long-term maintenance cost | Compounds (plugin licenses, security patches) | Predictable monthly hosting |
| 5-year total cost (typical) | $8,000–$25,000 | $15,000–$40,000 then steady state |
We're not in the business of trashing other platforms. Here's where WordPress is genuinely the better fit.
If your business generates 4+ blog posts per week and you have multiple editors, WordPress's editorial workflow (Gutenberg, multi-author roles, scheduling, taxonomies) is genuinely good. Few small businesses are actually in this category — but if you are, WordPress is reasonable.
Some niche functionality has only a WordPress implementation (certain LMS plugins, specific membership systems, particular WooCommerce-only integrations). If your business depends on that specific tool and migrating off it isn't viable, stay on WordPress.
WordPress's universality means any developer can pick up your site. If you anticipate switching agencies every 12–18 months, that portability is real value. Custom code is less portable — though good custom code is well-documented.
Magazines, news sites, and content-first publications make sense on WordPress. The CMS was originally designed for blogging and excels at it. If your website IS the product (rather than a sales tool for an offline product), WordPress is appropriate.
Where the trade-offs go the other direction — these are the situations where custom code outperforms WordPress.
Custom code loads in 0.3–0.8 seconds. The average WordPress site loads in 2–6 seconds. For a Sarasota or Bradenton plumber competing in the local pack, that speed gap directly translates to better rankings and more leads.
Every WordPress site we've audited has 15–50 plugins. Each one is a maintenance touchpoint and a potential security hole. Custom code ships the features your business actually needs and nothing else.
Generative Engine Optimization (GEO) — being cited by ChatGPT, Perplexity, Claude, Gemini, and Google's AI Overviews — depends on rich, linked schema markup, llms.txt, and clean structured data. WordPress can get there with the right plugin stack. Custom code ships with it by default.
A WordPress site goes down at 11pm because a plugin auto-updated and broke compatibility. A custom site doesn't have that failure mode. The code we wrote on day one is the code running at year five.
WordPress is cheaper to start. Custom is cheaper to run year-after-year. By year three, total cost of ownership crosses. By year five, custom is dramatically more cost-effective for a marketing site that doesn't need WP-specific features.
Specific business types we work with, and which platform actually fits each.
Custom wins easily. The site is mostly evergreen content (services, attorneys, locations, contact) with occasional blog posts. WordPress's plugin overhead is pure dead weight. Custom ships full E-E-A-T compliance, schema for attorney profiles, FAQPage schema for service questions — out of the box, no plugins.
Edge case. WordPress could work, but a simple custom admin with one form ("What's today's special?") performs better and is dramatically faster on the customer-facing side. Most restaurants we work with run on custom + a simple daily-update workflow.
Custom wins. The gallery is a simple media table; service pages are evergreen. WordPress's image-handling and gallery plugins (Modula, Envira, etc.) add 200KB+ per page for features the custom version handles in 10 lines of native code.
Depends. If the listings come from an IDX feed (real estate MLS data), custom can integrate the feed directly and outperform WordPress's IDX plugins on speed. If the agent manually edits each listing with rich custom fields, a WordPress + ACF (Advanced Custom Fields) setup might be more efficient to maintain.

Not for routine content edits. Every Suncoast Local site ships with a custom admin tuned to your specific content — hero text, service descriptions, FAQs, photos. The admin is simpler than WordPress's Gutenberg editor because it only shows the fields YOUR site has, not a generic content editor with 200 settings you never use.
You own the code and the database. We ship plain PHP that any developer who knows PHP can read and maintain — no proprietary frameworks, no custom build systems, no compiled binaries. The hosting is your account, not ours. Worst case, you hand the code to any PHP-literate developer and they can take over. (We've also never gone anywhere in 25+ years.)
Yes, with care. Every URL on your old WordPress site needs a 301 redirect to its new equivalent. We map old URLs to new URLs as part of the migration. Content gets carried over (we extract from your WP database). Rankings typically dip 2–4 weeks post-migration then recover and exceed pre-migration levels within 8–12 weeks if the new site is faster + better-structured (which it always is).
WordPress core is free. The actual cost of a WordPress site is hosting ($30–$200/month for anything decent), plugins (many $50–$300/year each, dozens total), theme licenses, security maintenance, and developer time when something breaks. The "free" sticker masks $5,000–$15,000 of annual operating cost on a real WordPress site. Custom sites have higher upfront cost but lower lifetime cost.
Yes, but for serious e-commerce we typically recommend Shopify (see our Shopify comparison) over either WooCommerce or fully-custom PHP. WooCommerce inherits all of WordPress's plugin overhead PLUS the complexity of e-commerce. For 5–50 products, custom PHP works fine. For larger catalogs or active stores, Shopify is the right tool.
A 15–30 page WordPress site typically migrates in 3–5 weeks: one week of content extraction and URL mapping, two weeks of design and build on the new platform, one week of redirect setup and QA, then launch. Larger sites with hundreds of posts take 6–10 weeks.
