1st type of Sourcing data – Website victors data, CRM data, Social channels, Search visitors, Display, Web Analytics, or any other source of data they own. This type of data used to call as 1st Party Data.

Suggestion from my end – Adobe Audiences Manager is the Best DMP tool for Us.
From the 2nd party data – I already said this 2nd party we receive from another company and it will come from various sources, like owned by 3rd parties or partner, offline sources, websites, apps or surveys etc… In this 2nd part, the date will get mostly into Location, interest, and behaviour.
How to use it:- Compare to 1st data this is a low-quality date but We know our business so we should collect related to our business from 2nd party data.
Note:- We should create a campaign based on user interests. and new offers on their interests.
From the 3rd party data – This data is related to online users and it looks like Gender, Age, Interests, and audience groups like ( Automobile, Travel, etc..)

15. How is the bounce rate calculated?
The definition of bounce rate is relatively simple to understand compared to other web analytics metrics. This does not mean that it is a superficial or unimportant fact since its analysis can reveal valuable insights.
The bounce rate offers information about the behavior of users of a website and shows their interaction on the page. Bouncing a web page consists of leaving it without interacting with the page in any way, such as writing a comment or clicking on a link. In other words, bouncing is about leaving the page before doing anything on it. The bounce rate is a parameter of Google Analytics to measure the interest of a website based on the visitor’s circulation through it, at a higher bounce rate, less content visited, which means that another page similar to yours with less rate Bounce will be classified as better quality.
Rb = Tv/Te
Where Rb is bounce rate
Tv is a total one-page visit
Te is total entrance visits
The formula for calculating the bounce rate is quite clear and can be summed up in a simple equation: the number of users who leave the page after just seeing the landing page (the first page they see on the website) and who do not interact on it divided by the total users of the site. Therefore, if 40 users leave without taking any action on a page and we have 100 users in total, the bounce rate is 40%.

Google Sandbox effect, also known as sandboxing and/or Google penalty is the name that is given to the observation of the system by which Google ranks a large number of web pages in the index of its own. Not everybody is sure of its existence but it is believed that this filter came in the Google algorithms more than a decade ago in 2004, somewhere around March.
When a website is active and working well at its level but still not showing in the Google search engine result pages then It might be in Sandbox. If you are trying to rank the newly-registered domain by using the best keywords and Google still not giving the exact value to search results than the Sandbox might be the reason.
The Google Sandbox Theory is that Google puts new websites into a “Sandbox” before they can rank well in a Google search and make their way to the top of a search result. Google wants to make sure that a website is legitimate and not just a fly-by-night website that was set up with bad intentions before it ranks it prominently on the SERP (search engines results page). The theory is used to explain why newly-registered domains or domains that change ownership hands frequently rank poorly no matter how well they are optimized.
