Page titles: Check if all page titles are optimized and none are duplicated. META description: Verify all page META descriptions are relevant and optimized. Custom search: Search and check all pages for custom text and code, e.g. Google Analytics. Spell check: Check websites for spelling errors using a variety of spell checker dictionaries.
