Is site:domain.com + keyword a good indicator of the quality of a page?

[nicole.healthline]

Are the results provided by site:domain.com + keyword a good indicator of the quality of certain pages?

For example, should the first result be more relevant, have a higher number of links, etc than the second result?

Ostensibly it's a good way to find out which are the strongest pages on your site for a particular keyword.  It won't be indicative of the strength of the page when compared to anything else on the web, but if any page from your site is going to rank for that keyword, it will probably be the first one that Google shows on that query.

It's not going to tell you exactly what factors are causing it (whether it be the on-page optimization, or the links), so any analysis you would want to do would be the same as you would have to do when looking at a regular SERP.  Google thinks that first page is the most relevant page on your site for that keyword.  Why?  You can get some ideas by comparing them, but it's never going to be 100% obvious.

It's a great idea - I actually never thought of doing that to check for keyword cannibalization within a site, make sure the page I want ranking to actually the first - thanks!.
