Could not fix issues reported by Smartcrawl SEO Checkup

Smartcrawl reports six issues that I have difficulty understanding. Like I have added focus keyword still Checkup shows:
‘We could not detect any keywords in your URL’
Also I have disabled and enabled the “Hide redundant canonical link tags”. Still SEO Checkup shows:
‘Duplicate content spread across multiple URLs can have a negative impact on your page rank. Using a canonical URL for products or content that is accessible under multiple URLs or websites can allow them to exist without harming your rankings.’
