The “Perfectly Optimized” Page infographic states that there is no such thing as a “Perfect Page”. But don’t be discouraged! Moz.com presents 3 key points to be followed to increase user happiness and outreach.
One important takeaway from this post should be that modern on-page SEO is about juggling competing priorities. In general, my recommended ordering of those priorities is as follows:
Create a page that is uniquely valuable to your targeted searchers.
If at all possible, make the page likely to earn links and shares naturally (without needing to build links or prod people).
Balance keyword targeting with usability and user experience, but never ignore the critical elements like page titles, headlines, and body content at the least.
There’s no such thing as a “perfectly optimized” page, but I took a stab at drawing up the mythical beast anyway.
