Optimizing Business Catalyst Templates with Dreamweaver: Best PracticesBusiness Catalyst was Adobe’s hosted CMS and e-commerce platform that integrated with Dreamweaver to let designers build, manage, and publish sites with CMS-driven content, forms, and online stores. Although Business Catalyst reached end-of-life and many sites have migrated away, projects still exist that require maintaining or optimizing Business Catalyst templates using Dreamweaver. This article covers practical, actionable best practices for optimizing those templates for performance, maintainability, and easier migration later.
Why optimize Business Catalyst templates?
Even if a site will be migrated soon, optimization pays off by:
- improving page load and user experience while the site remains live,
- making templates easier to understand and port to another platform,
- reducing server processing overhead for dynamic modules,
- lowering risk of content or layout breakage during edits.
Key focus areas: template structure, CSS and JS handling, Business Catalyst modules and tags, responsive layout, image handling, accessibility, testing and migration readiness.
1. Start with a clear template architecture
- Use Dreamweaver’s template (.dwt) system or a consistent include structure to separate content from layout. Create master templates for:
- Global header (navigation, logo, meta tags),
- Footer (analytics, footer navigation),
- Page shell (content regions, sidebars, module placeholders).
- Name files consistently (header.html, footer.html, shell.dwt) and keep a small number of global templates to minimize duplication.
- Keep Business Catalyst-specific modules and scripts centralized in the header or footer includes so updates apply site-wide.
Benefits: faster edits, fewer inconsistencies, simpler migration mapping.
2. Minimize and defer Business Catalyst server-side module rendering
Business Catalyst modules (e.g.,
Best practices:
- Cache outputs where possible: for repeatable lists that change infrequently, use Business Catalyst’s built-in caching features or reduce the frequency of dynamic calls.
- Limit items returned by modules with concise queries and paging. Don’t request entire catalogs or huge lists unless necessary.
- Use conditional logic to prevent rendering modules on pages that don’t need them. For example, wrap modules in simple server-side conditionals or include them only in templates used by those pages.
- Where feasible, convert large or static lists into flat pages or JSON files served as static assets (helps both performance and portability).
Result: reduced server load and faster initial rendering.
3. Optimize CSS and JavaScript management
- Consolidate CSS: combine framework and custom stylesheets into as few files as practical. Use Dreamweaver’s CSS features (or external build tools) to maintain modularity during development while shipping concatenated files for production.
- Minify and version assets: minify CSS/JS and append version query strings (e.g., styles.min.css?v=20250901) so caches update predictably.
- Defer non-critical JS: place scripts at the end of the body or use async/defer attributes to prevent render-blocking.
- Avoid in-template inline CSS and JS for maintainability. If inline code is necessary for Business Catalyst variables, keep it minimal and documented.
- Prefer progressive enhancement: make templates functional without heavy JS, then layer interactivity.
Example (pattern): load critical CSS in head, defer analytics and third-party scripts to footer, load non-essential widgets after DOMContentLoaded.
4. Use responsive design and fluid layouts
- Implement a mobile-first approach: design breakpoints and styles starting from smallest devices upward.
- Use CSS grid and flexbox for layout where supported; fallback gracefully or include simple float-based fallbacks if wide legacy browser support is needed.
- Make Business Catalyst module containers fluid: give module output wrapper elements flexible widths and avoid fixed pixel dimensions that break on small screens.
- Test responsive behavior in Dreamweaver’s device preview and on real devices. Check module-rendered content (like blog lists or product grids) for overflow, truncation, or misalignment.
5. Optimize images and media
- Serve appropriately sized images: don’t insert full-resolution originals into templates. Use multiple sizes or responsive srcset where possible.
- Compress images: use modern formats (WebP, AVIF where supported) and reasonable compression. Keep a balance between quality and size.
- Lazy-load offscreen images using loading=“lazy” when supported; for critical above-the-fold images, preload selectively.
- For Business Catalyst-managed images (e.g., from the file manager), ensure you reference versions sized for intended use rather than raw uploads.
Benefit: significantly smaller page weight and faster load times.
6. Improve accessibility and semantic markup
- Use semantic HTML5 elements (header, nav, main, article, footer) in templates.
- Ensure navigation uses proper ARIA roles and that interactive elements are keyboard accessible.
- Provide alt attributes for images and meaningful link text; avoid “click here.”
- Ensure forms (including Business Catalyst forms) have labels, error messages, and are accessible to screen readers.
- Test with automated tools (axe, Lighthouse) and manual keyboard-only navigation.
Accessibility increases usability and reduces future rework during migration.
7. Manage third-party scripts carefully
Third-party widgets (chat, analytics, ads) can bloat pages and slow rendering.
- Audit all third-party tags and remove unused ones.
- Load non-essential third-party scripts asynchronously and only on pages where they’re needed.
- Consider consent management for privacy compliance; place trackers behind consent when required.
- For critical tracking, use server-side or proxy approaches where feasible to reduce client-side impact.
8. Prepare templates for migration
Because Business Catalyst is deprecated, many sites will move to other platforms. Make templates migration-friendly:
- Separate content from markup: keep content regions clearly identified and avoid mixing content with layout or script logic.
- Document custom modules and data sources: create a migration map listing Business Catalyst modules used, what data they pull, and approximate equivalents on target platforms (e.g., CMS collections, headless APIs).
- Export sample content: generate exports of collections, product catalogs, and key pages to verify data mapping.
- Favor standard HTML/CSS/JS patterns rather than proprietary tags embedded throughout. Where BC tags are used, isolate them in includes so replacements are localized.
This reduces migration effort and cost.
9. Monitor and test continuously
- Use performance audits (Lighthouse, WebPageTest) to identify bottlenecks; test both mobile and desktop.
- Set up a QA workflow: use staging copies of templates and Business Catalyst sites for testing before publishing changes.
- Use browser devtools to profile load times, network requests, and rendering. Pay attention to Time to First Byte (TTFB) for server-side module calls.
- Track user metrics (Core Web Vitals) and regress after changes.
10. Practical Dreamweaver tips and tools
- Use Dreamweaver’s Live View to inspect dynamic Business Catalyst output and quickly tweak CSS around module output.
- Create code snippets for recurring Business Catalyst tags or common module wrappers.
- Use Find/Replace across the site to update repeated include references, asset links, or outdated module calls.
- Keep a site-wide CSS reset or normalize file to reduce cross-browser inconsistencies introduced by module HTML.
Example checklist (quick reference)
- Centralize header/footer/includes — done
- Reduce server-side module calls and add caching — done
- Concatenate and minify assets; use versioning — done
- Implement responsive, mobile-first CSS — done
- Resize/compress images; use lazy-loading — done
- Use semantic HTML and ARIA where needed — done
- Audit and defer third-party scripts — done
- Document modules and prepare migration map — done
- Run Lighthouse and remediate high-priority issues — done
Optimizing Business Catalyst templates in Dreamweaver is largely about reducing server-side overhead, cleaning up front-end assets, and structuring templates so they’re maintainable and portable. Even with Business Catalyst no longer a mainstream choice, applying these practices will yield faster, more accessible pages today and make future migrations far less painful.
