Web analytics tools and metrics used for monitoring 
    performance are covered in Section 
    Metrics of Chapter Web Analytics. 
    The section outlines a list of metrics that are useful for assessing a website’s health and performance. 
    The key metrics relating to acquisition, engagement and conversion are as follows:
    - Unique Visitors: The number of users who visit the site over the reporting 
        period.
    
- New Visitors: The number of first-ever unique visitors (Assumes cookies

- Repeat Visitors: The number of unique visitors who visit the site more than 
        once during reporting period.
    
- Conversions: Number of visitors who complete a target action such as 
        purchasing something, subscribing to newsletter etc.
    
- Conversion Rate: Proportion of visitors who perform a target action.
    
- Bounce Rate: Proportion of visitors who leave the site without visiting any 
        page other than their landing page.
    
- Abandonment Rate: Proportion of visitors who start but do not complete a 
        target action.
    
- Cost per Conversion (CPCon): Cost of ad campaign divided by the total number 
        of conversions resulting from the campaign. (Inbound URL from ad is tagged).
Depending on your business imperatives and initiatives, certain metrics may hold 
    greater significance. For example, if your primary objective is to generate website traffic, it 
    is important to monitor metrics such as unique visitors, new visitors, repeat visitors, and 
    bounce rate. On the other hand, if your focus is on lead generation through gated offers, you 
    should track metrics such as conversions, conversion rate, and cost per conversion. It is 
    essential to identify the most relevant metrics for your specific objectives and regularly monitor 
    and analyse them to optimize your digital marketing strategy and improve performance.
