Frequently asked questions
Can other sites on my IP affect SEO?
Google says shared hosting doesn't negatively impact rankings directly. However, if your IP gets blacklisted due to a spam neighbor, your email deliverability suffers. Server performance from noisy neighbors does affect speed metrics.
How many domains can share one IP?
No hard limit. Shared hosting commonly hosts 100-500 domains per IP using virtual hosting. Budget hosts pack thousands. Dedicated IPs give one IP per site.
Why check sites on my IP?
Email reputation mainly. If a neighbor sends spam, the entire IP can be blacklisted. For security, a compromised neighbor could be used to attack others on the same server.
Does a dedicated IP improve performance?
The IP itself doesn't — it's the dedicated resources (CPU, RAM) that matter. The main benefit is email reputation and SSL compatibility with very old browsers.
