im using a new real ip from my isp and anti detect browser , yet site still detects im not a unique visitor. How is that possible? also tried it with a residential proxy and anti detect browser. Unique visitor means first time visiting site

Are you using a fresh instance of the browser so there's no cookies?

When a site detects you are not a unique visitor, even though you are using a residential proxy and anti-detect browser, it may be because:

Cookies: Websites use cookies to track users' browsing history and behavior. If you have previously visited the site, cookies may have been stored on your device, allowing the site to recognize you as a returning visitor. To prevent this, you can clear your cookies and browsing data before using the proxy and anti-detect browser.

IP address reputation: Your residential proxy's IP address may have been previously associated with suspicious or malicious activity, causing the website to flag you as a potential threat. This can happen if the IP address has been used by others for spamming or other nefarious purposes. To avoid this, choose a reputable proxy provider that maintains a clean pool of IP addresses.

Shared IP addresses: If you are using a shared residential proxy, your IP address may be shared with other users. This means that if another user engages in suspicious activity, it may affect your ability to access the website. To avoid this, consider using a dedicated residential proxy or a proxy provider that offers sticky IP addresses.

Website's anti-fraud measures: Some websites have sophisticated anti-fraud measures in place to detect and block automated traffic or suspicious behavior. These measures may include analyzing your browsing patterns, mouse movements, and other factors to determine if you are a real user. To bypass these measures, you may need to use more advanced anti-detection tools and techniques.

You could appear as an outlier in their traffic, it's especially easy to detect if said website doesn't normally get visits. This is irrespective of what data you bring to the table.

Imagine looking at a picture of white noise, you shouldn't be able to distinguish any patterns. But if you start putting black dots in one area, it becomes noticeable very quickly.

You're essentially painting these black dots unless you articulate traffic with respect to the probability constraints.

I came across this topic quite late, but I'd like to add to the answers.
There's something called a TCP/IP fingerprint. It's a collection of characteristics from the source of an internet request (network characteristics of the device, operating system, and many more TCP/IP parameters). When using a proxy, this fingerprint is "pulled" from your proxy server. It's a rather complex, multifactorial thing, some components of which you can check online at https://browserleaks.com/ip and https://www.deviceinfo.me/.
