Short answer
Which platform should a corporate site be built on?
The decision is not a technology preference but two questions: who updates the content, and how many external systems the site connects to. If a marketing team updates copy daily and integrations are few, WordPress is a reasonable choice. If page types change often, the site is multilingual and speed targets are measurable, a custom build ends up cheaper. W3Techs puts WordPress on 40.3% of all websites.
Key takeaways
- WordPress costs show up not at setup but in year two: plugin updates, version incompatibilities and security patches are a standing maintenance line.
- What slows a site down is usually not the platform but seven plugins doing the same job; plugin count is an architecture decision, not a preference.
- The real risk of a custom build is not technology but dependence on one developer — choosing a widely used framework removes it.
- The gap opens up on multilingual work: in WordPress multilingual arrives as a plugin, in a custom build routing and hreflang are part of the design.
- Whichever platform you pick, modelling the content around your actual page types matters more than the platform choice.
Which two questions does the decision come down to?
The argument is usually conducted in terms of technology, but the decision resolves on two operational questions. First: who updates the content, and how often? If a marketing team publishes several pages a week, the strength of the admin interface is a decisive advantage. Second: how many external systems does the site connect to? The more connections, the less an off-the-shelf platform bends.

Where does WordPress actually cost you?
WordPress's ubiquity is an advantage: per W3Techs it runs 58.8% of sites whose CMS is known and 40.3% of all websites. Ubiquity makes support easy to find and teams easy to swap. The cost sits elsewhere: setup is cheap, maintenance is continuous.
- Plugin maintenance: every plugin has its own update schedule and no guarantee of compatibility with the others. On a site with fifteen plugins, updating now needs a maintenance window.
- Security: being ubiquitous also means being a target; an unpatched plugin becomes the weakest link in the site.
- Speed: the extra scripts and stylesheets a theme and its plugins emit are the first obstacle you meet once you set measurable speed targets.
- Version lock: when one plugin does not support a new PHP release, the site stays on the old one and eventually becomes un-upgradable.
What is the risk of a custom build?
Most people look for the risk in the wrong place. The danger is not that it is custom but that only one person understands it. A widely used framework (React/Next.js, say), a standard data model and a readable repository take you out of dependence on a single developer. The clause to look for: source code, documentation and deployment configuration transfer on delivery.
Frequently asked
Is WordPress enough for a corporate site?
- For most corporate sites, yes. Where it falls short is when page types change often and the content is structural: if every service has different fields, if references need four separate templates, the data model starts being assembled from plugin on plugin and the maintenance cost overtakes that of a custom build.
Does buying a theme make sense?
- If the budget is tight and your content structure fits the layouts the theme offers, yes. The risk: purchased themes carry a great many features for every eventuality, and that code loads whether used or not. The question when choosing one is not how good the design is but how many plugins it depends on and how much of the page weight comes from features you will never use.
Can I move off WordPress later?
- Yes, but the cost depends on how the content is stored. If it sits in structured fields, moving is a data export; if it was produced by a page-builder plugin, markup and text are tangled together and every page has to be cleaned by hand. That is the part of a plugin decision that gets billed three years later, not today.
