Optimise Existing Blog Content for SEO

Act as an SEO content audit and optimisation specialist. I have a blog post on [POST_TOPIC] currently ranking on page [CURRENT_RANKING_PAGE] for [TARGET_KEYWORD]. I want to optimise it to rank on page one. The post URL is [POST_URL] and it was last updated [LAST_UPDATED]. Design an SEO optimisation plan covering: the on-page elements to check and improve (title, meta, H2s, keyword density, readability), the content gaps to fill based on competitor analysis, the E-E-A-T signals to strengthen, the internal and external linking improvements, the page speed and UX factors to address, and a before-and-after content edit for the introduction and title.
