When I typed site:example.com in Google's search box, it's displaying a different title and meta description, but the thing puzzling me is the site URL is being displayed correctly and redirected to my blog page.However when I type only brand name example in the search box and click on the first result, it's redirecting me to different site.Note: This issue is not limited to Google. It also for all major search engines. Also this is regarding my home page only, all other post pages are working well.I don't know what's going on here. Anyone else have the same issue? How do I fix this?Update:When I fetch as Google, it shows me wrong data shown in following image:Info: My website is in WordPress and hosted on Windows shared server. I'm using the SEO by Yoast WordPress plugin for SEO before that I was using Basic SEO plugin.When I was using Basic SEO plugin I was working perfectly but when I moved to SEO by Yoast plugin after that I come to know this issue. Not sure if that upgradation causing this issue.
