The conditions to meet are: Use Google’s Mobile-Friendly Test to evaluate the responsiveness of your site. Avoid pop-ups that block the mobile viewing experience. Make sure that elements are big enough and easy to tap on mobile screens.

3. Crawlability and Indexing
Search engines need to crawl your site to rank it. Ensure you’ve: Created and submitted an XML sitemap via Google Search Console.
Configuring robots.txt to allow indexing of the most necessary pages while blocking the sensitive ones. Using Hreflang tags for multilingual sites so that they properly communicate the URL to the search engines.
4. IP Address and NAT Optimization
Efficient IP management can reduce site downtime and provide smooth access to the site. Private IP Address: It is used within internal networks which would be best for security.
Public IP Address: Allows external to the system; however, it requires good firewall protection. NAT (Network Address Translation): Static NAT: A technique that enforces a strict pairing between a private and a public IP so that the network is not needed.
Dynamic NAT: Provides the necessity to reserve IPs from a set and allows to handle bigger traffic better. Port Address Translation (PAT): Manages more devices such that they all use the same public IP by optimizing it.
5. Structured Data Implementation
Structured data (Schema Markup) gives your website more of a richer appearance in the search results through what we call rich snippets.
For the addition of schema types, use JSON-LD format. For Example FAQ, How-to, or Product. With Google’s Rich Results Test tool, check your implementation.
