Which method of website ownership verification in Naver Webmaster Tools provides the *mostreliable and persistent verification?

DNS record verification provides the most reliable and persistent method. Unlike HTML tag or file upload verification, which can be easily removed or accidentally deleted during website updates or redesigns, a DNS record remains in place unless deliberately altered at the domain registrar level. This makes it significantly less susceptible to unintended verification loss. By adding a TXT or other specified record to the domain's DNS settings, you are establishing a permanent and authoritative link between your Naver Webmaster Tools account and your website. This ensures continuous access to website data and tools within Naver Webmaster Tools, even if the website undergoes significant changes.
