Sitemaps

Put whatever sitemap address you have into your browser. If it opens (without any errors), that’s the correct sitemap address to use.

If you’re still in doubt, please contact your SEO plugin’s authors: https://www.ads-software.com/support/plugin/wp-seopress/

In google search also , site tile, description are not working same as plugins.

Consider your site titles and descriptions as a “hint” to “influence” Google… but there’s no guarantee that Google will use them.

That doesn’t mean there’s any problem with your site. Please see Google’s own guidance on this: https://developers.google.com/search/docs/appearance/title-link

Good luck!
