Hi YogitaBist,
You are looking at an old question so those links are dead now unfortunately. Actually, the correct answer is also old. That is for the legacy version of the Analytics & Target integrations. For recently implemenations you should be using the profile and audiences integration method. This is more robust. To target an activity off of Analytics data you can share a segment from Analytics to the Marketing Cloud, then it will automatically show up as an audience with Target. OR you can create an audience in the Audiences Library (Marketing Cloud > Profiles & Audiences > Audience Library). You can define an audience based off of Analytics evars or events.
Create and audience in help will give you the details.
