My client is facing site:www issue in google.co.uk
When I type search query site:www.blinds4uk.co.uk
in Google SERP`s, the home page is not appearing. but with capital letters search query - SITE:WWW.BLINDS4UK.CO.UK
Google showing the home page.
Please let me know that why it`s happening and what is the solution.
Note: I already checked crawling, indexing, robots.txt and sitemap.xml - Everything is ok and working well.
