A 2026 redesign should prioritize composable structure, speed control, accessibility support, admin security, privacy workflows and built-in personalization. A CMS, or content management system, is the software that stores, assembles and delivers pages and structured content. Marketing and engineering both live with the choice. The right features reduce rework, protect visibility and reduce legal and security risk.
Official resources:
- Check Core Web Vitals thresholds for LCP, INP and CLS — Verify Google's good thresholds to benchmark CMS theme performance before redesign.
- Verify WCAG 2.2 accessibility success criteria — Check the testable criteria to require in CMS templates and content workflows.

Can you reuse content across channels without rework?
Look for a composable CMS built on MACH: Microservices, API-first, Cloud-native SaaS and Headless. According to the MACH Alliance, teams can assemble, replace and scale capabilities independently and deliver structured content omnichannel via APIs, as described in MACH principles explained.
That matters when one product update must feed the site, app, kiosk and partner feed. Marketing gains faster launches while engineering gains independent scaling. The limit is higher integration governance, so assign owners for APIs, contracts and version changes.
Will the design stay fast under real traffic?
Ask how the theme, templates and plugins protect Core Web Vitals. Google defines good scores as LCP up to 2,500ms, INP up to 200ms and CLS up to 0.1 at the 75th percentile of real views, noted in Google's threshold guidance.
Choose themes that limit blocking JavaScript, stabilize layouts and support caching and CDN use. Failing pages risk lower search visibility and higher bounces.
- Block heavy scripts from the critical path
- Reserve space for images, embeds and banners
- Cache pages and serve static assets from a CDN
Will the site meet accessibility duties?
Plan for the EU European Accessibility Act, Directive 2019/882, which applies from 28 June 2025 to consumer services including e-commerce, banking, e-books and communications. The EU summary says services must be perceivable, operable, understandable and robust, while microenterprises providing services are exempt.
Use W3C WCAG 2.2 of 12 December 2024 as the build target. The W3C says it provides testable, technology-agnostic criteria across desktop and mobile needs, and content conforming to 2.2 also conforms to 2.0 and 2.1, explained in WCAG 2.2 guidance. That makes policy upgrades simpler because one test set covers earlier versions.
Can you prove who changed what and handle consent?
Require strong admin controls and usable records. CISA Secure-by-Design guidance urges products to make MFA opt-out for admins, support standards-based SSO and provide high-quality audit logs at no extra charge, detailed in CISA Secure by Design guidance. Logs alone do not stop attacks without monitoring and patching.
Pair them with least-privilege roles, timely updates and alerts for control bypass. EU visitor data needs consent and lifecycle workflows. EU Regulation 2016/679, Articles 6-7, allows processing only under six bases including consent and requires proof of freely given, specific and informed consent with withdrawal as easy as giving it. Your CMS should store consent records, minimize collection and support retention and deletion.
- Enforce MFA and SSO for staff and vendors
- Keep tamper-evident logs for publishing, access and consent events
- Add retention rules and simple deletion for EU requests
Can marketing launch variants without copy-paste?
Shortlist platforms with built-in localization, variant generation, audience segmentation and experimentation under brand and governance rules. Contentful's 2025 personalization reporting describes these generative actions inside the CMS, letting teams test messages faster.
Use them to localize offers, test headlines and tailor blocks by segment. Keep human review for accuracy and bias before publishing.
