Sitecore to WordPress CMS Migration

Seattle Foundation WordPress website

Committed to Accessible WordPress Websites for Nonprofits

This project involved cloning the existing Seattle Foundation visual layout and design from a website powered by Sitecore into a new more accessible, performance-optimized site powered by a WordPress Content Management System.

Foundation staff wanted a CMS that was simpler and easier to maintain. Project challenges included poorly structured Sitecore-exported XML data files, a low contrast color palette, and a short timeline. Content management was the primary dependency for the new website launch, since hundreds of posts needed to be migrated.

The site is working great! We love it and you did a fantastic job.

Performance

Mobile speed index improved 69%, from ~9.5 to 2.5 seconds [source: WebPageTest]. This was achieved by reducing overall homepage size 89% – from 5.7 Mb to 639 Kb, and significantly reducing Javascript 95% – from 2.2 Mb to 112 Kb. Overall, web server requests, the primary contributor to slow page loads, decreased 49%. Finally, DNS management was moved to a Cloudflare CDN for better performance, redundancy and security.

Accessibility

Improvements include higher contrast colors to better adhere to Web Content Accessibility Guidelines (WCAG); increased font sizes; a navigation skip link; and removal of auto-rotating content sliders.

Seattle Foundation manages over $1 billion in philanthropic investments. 2022 marks the 1-year anniversary of the Foundation’s REPAIR initiative (Racially Equitable Philanthropy Aimed at Initiating Relationships), with a minimum investment of $25 million to Black-led organizations around Seattle; and its Center for Community Partnerships striving to achieve greater racial and economic equity in the region. The Foundation also incubated SkillUp Washington – a workforce funders collaborative connecting employers, post-secondary training and low-income adults.

WordPress Consulting for Private Companies and Nonprofit Organizations

A website conversion from Joomla into WordPress for SoundEarth Strategies, a professional services firm that provides environmental and engineering consulting services in the Pacific Northwest. The marcom staff wanted to clone the existing Joomla website into a more intuitive, user-friendly WordPress CMS, already in use by a subsidiary.

Like WordPress, Joomla is a PHP-based open source Content Management System. With an estimated 2.5% share of market – it is estimated to be the fifth most popular CMS after WordPress (65% market share), Shopify (6.5%), Wix (3.4%) and Squarespace (3%). There are approximately 6,000 extensions available for Joomla vs. over 60,000 for WordPress.

WebPageTest Speed Index shows a 62% improvement in mobile page load speed by reducing web server requests almost 20% and reducing page size from 3 Mb to 2 Mb.

Google Lighthouse accessibility benchmarks also improved markedly from 79 to 98/100. This is important for federal contractors who
must legally follow Web Content Accessibility Guidelines (WCAG) level AA under the American Disabilities Act. Improvements included accessible form fields, increased font sizes, and higher color contrast ratios.

Developing Outstanding WordPress Websites for 12 years

Presenting my latest website overhaul for Early Music Seattle, a nonprofit presenting classic concerts at venues around the city – including Benaroya Hall, Bastyr University Chapel, Federal Way Community Performing Arts Center, Langston Hughes Performing Arts Institute, and Town Hall.

This project involved converting a custom-built WordPress Theme and migrating content into a new performance-optimized Theme (_Underscores). The Block Editor was integrated for more robust layout and styling. Accessibility improvements included higher contrast colors, navigation skip links, keyboard accessible menus, and mobile-clickable phone numbers. A new branded event calendar was also integrated, with the ability for community organizations to submit third-party events. By reducing server requests 45% and reducing page size 85%, page load speed now ranks in the upper 10th percentile of sites.

Building WordPress Websites with Equity and Accessibility in Mind

Sometimes a website with reasonable benchmarks can still perform poorly. This dental foundation website is a perfect example. The former site’s 2.2 Mb page size was well within the industry median; and 84 server requests is above optimum, but certainly not atrocious. Still, migrating from a custom-coded Theme to a WordPress-approved Theme (_Underscores) significantly improved perceived page load speed, despite server requests increasing and page size decreasing nominally.
