I utilized a staging site provided by DreamHost to develop and try out new upgrades for their large financial site. Projects in progress include a theme change, testing a new mobile page creation plugin, and deciding between Yoast and MathRank for SEO. They learn from their initial errors on the staging site and plan to document their actions and streamline the plugins and ads on the site. They also note the challenges of designing mobile pages and testing SEO tools. For SEO testing, the author considers conducting tests on the live site, emphasizing the importance of site back-ups.
