The SEO assessment found that the website needed optimization of its title, meta description, images, internal and external links, and keywords. The plan was to shorten the title to 70 characters or less, reduce the meta description to 300 characters, add meta keywords and image alt text, increase internal links to at least 30 and external links to 50 or more, and optimize content with keywords like online bookkeeping, tax, Xero accounting, virtual assistance, and social media management.
