While those are great tips, I think some of that is suseceptible to statistical analysis processes. If many SEOs trying to game the system are following the recipe on those pages where does that put you on the bell curve of sites likely to spam?

Martinibuster is right. Following well-intentioned guidelines that were written several years ago could lead to SEs seeing your site as over-optimized or spammy.

You asked "How will i able to know if my page if fully optimized for search engines and users?"

For users all that is needed is that the visual presentation immediately tells the user what the page is about. For instance a clear header, maybe an image, and some appropriate text. Users never look at the document title and are unaware of stuff like H1 tags.

To get users to your site the title and meta tag description have to be appealing when they see it in SERPS, but that's all. The URL hardly ever gets looked at.

The problem is SEs aren't visual and you have to tell them what the page is about by optimizing. The pitfall is to over do it. It's best to stay well beneath any spam threshold that SEs might set now or in the future. For instance make sure you don't have too much 'hidden' text, e.g., in alt or title attributes, or use too many H tags, in fact anything that makes the page stand out as abnormal from what would be expected in a 'normal' page.
