Hi @srividyavenkat
bear in mind that the last touch channel can also be overridden by other marketing channels. The marketing channel is not persisted for individual pages but globally for the visitor.
So, if the user came to your site through an email campaign (non-indexed page), and then later googled your site and came back through organic search to an indexed page such as the homepage, this will likely override the last touch channel with "Natural Search" and Google as referring domain.

"The ‘Last touch channel’ dimension reports the most recent marketing channel a visitor matches with during that visitor’s engagement period (30 days by default). This dimension is valuable in understanding which marketing channels drive traffic to your site that result in conversions, allowing you to focus marketing efforts in areas that are most effective."
It is also affected by how you set up your marketing channels in the Marketing Channel Manager and which channels are allowed to override the last touch channel.
By default, "direct" and "internal" are disabled.
