Mobile optimization is no longer a \u201cnice to have\u201d for websites that want to rank well in search. Because most users browse, compare, and buy on phones, Google evaluates mobile experiences very seriously.

If your desktop site contains detailed content, structured data, internal links, and optimized images, but your mobile version hides or removes them, search engines may not fully understand the value of your pages. A mobile site should not be a weaker copy of the desktop experience. It should offer the same useful content in a format that works beautifully on small screens.<\/p>\n\"Google\n
