And here are the SEO tips for you.

#1: The sitemap location in robots.txt does not matter
John Mueller answers a question about whether it makes any difference in terms of SEO if you indicate the URL of your sitemap in robots.txt. No, it does not matter.
#2: The length of a URL is a very weak signal when it comes to canonicalization
The take-home message from this question asked on Twitter is that Google uses URL length very lightly for canonicalization purposes. 
#3: Google does not see the content behind Captchas
If parts of your content are only visible after a Captcha code is verified, then Google cannot see this content. This is the question from the Google SEO Office Hours with John Mueller.
