I am a novice to SEO, I am building a website, I need to include many links to external websites. While going through a couple of sites, when they are linking to external website in anchor tag link section they are linking to an internal link and again mapping to actual external website. I googled about this stuff but unfortunately I am not able to find the relevant stuff. please explain me how I can accomplish this.
EXample g.SITENAME dot com/details/0/2obr3ac
SITENAME dot com/details/popup/ as4ow34
