High-quality competitor analysis requires complete stealth, otherwise you risk receiving unreliable information or losing access to the resources you need. Using a regular browser de-anonymizes your visits, allowing competitors to track your interests. To conceal your actions and collect accurate data, it’s worth using an anti-detection browser with the ability to quickly change GEOs via built-in proxies. For confidential and accurate market research, I recommend link using reliable tools for anonymous surfing. This will allow you to explore any foreign websites as a regular local user, collect current prices and competitors' creatives, while remaining completely invisible to their analytics systems.
