In electronic commerce, conversion marketing is the act of converting site visitors into paying customers. However, different sites may consider a "conversion" to be some sort of result other than a sale. One example of a conversion event other than a sale is if a customer were to abandon an online shopping cart, the company could market a special offer, for example, free shipping, to convert the visitor into a paying customer. A company may also try to recover the abandoner through an online engagement method such as proactive chat in an attempt to assist the customer through the purchase process.
Measures
The efficacy of conversion marketing is measured by the conversion rate, i.e. the number of customers who have completed a transaction divided by the total number of website visitors. Since conversion rates for electronic storefronts are usually very low, conversion marketing can be a useful way to boost this number, online revenue, and overall website traffic.
Conversion marketing attempts to solve the issue of low online conversion through optimized customer service. To accomplish this it requires a complex combination of personalized customer experience management, web analytics, and the use of customer feedback to contribute to process flow improvement and overall site design.
The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example, the oxidative rusting of iron under Earth's atmosphere is a slow reaction that can take many years, but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second.
In internet marketing, conversion optimization, or conversion rate optimization (CRO) is a system for increasing the percentage of visitors to a website that convert into customers, or more generally, take any desired action on a webpage. It is commonly referred to as CRO.
History
Online conversion rate optimization (or website optimization) was born out of the need of e-commerce marketers to improve their website's performance in the aftermath of the dot-com bubble. As competition grew on the web during the early 2000s, website analysis tools started appearing and an awareness of website usability rose. This prompted internet marketers to become more measurable with their marketing tactics and focus on improving the website's user experience. In 2004, new tools were introduced which enabled internet marketers to experiment with website design and content variations to determine which layouts, copy text, offers and images would perform best. This gained more traction in 2007 with the introduction of the free Google Website Optimizer. A research study conducted among internet marketers in 2014 showed that 59% of respondents thought that CRO was "crucial to their overall digital marketing strategy".

In this video you are going to learn what the reaction rate is and some ways of measuring reaction rate.
Reaction rate is a measure of how quickly the reactants in a reaction change into the products of the reaction.
The rate of a chemical reaction can be measured in two ways:
1) The first way is to measure how quickly the reactants (the substances on the left of the arrow in the equation) decrease.
2) The second way is to measure how quickly the products (the substances on the right of the arrow in the equation) increase.
Example for 1: Measuring how quickly reactants decrease.
We will look at the reaction between marble chips (calcium carbonate) and hydrochloric acid.

Rates of Reactions - Part 1 | Reactions | Chemistry | FuseSchool
In this video you are going to learn what the reaction rate is and some ways of measuring reaction rate.
Reaction rate is a measure of how quickly the reactants in a reaction change into the products of the reaction.
The rate of a chemical reaction can be measured in two ways:
1) The first way is to measure how quickly the reactants (the substances on the left of the arrow in the equation) decrease.
2) The second way is to measure how quickly the products (the substances on the right of the arrow in the equation) increase.
Example for 1: Measuring how quickly reactants decrease.
We will look at the reaction between marble chips (calcium carbonate) and hydrochloric acid.
As the reaction proceeds, the reactants lose mass because carbon dioxide gas is given off. We can measure the decrease in mass of reactants by using this type of apparatus with a conical flask stopwatch, cotton wool plug and balance.
Based on our measurements, we plot a graph of ‘mass of reactants against time’.
The rate of reaction at point A is given by the gradient at A which is y/x and the rate of reaction at point B is given by the gradient at point B which is y’/x’ .
Example for 2:
Instead of measuring the loss of mass of the reactant we can also measure the gain in volume of the product carbon dioxide.

Rates of Reactions - Part 1 | Reactions | Chemistry | FuseSchool
In this video you are going to learn what the reaction rate is and some ways of measuring reaction rate.
Reaction rate is a measure of how quickly the reactants in a reaction change into the products of the reaction.
The rate of a chemical reaction can be measured in two ways:
1) The first way is to measure how quickly the reactants (the substances on the left of the arrow in the equation) decrease.
2) The second way is to measure how quickly the products (the substances on the right of the arrow in the equation) increase.
Example for 1: Measuring how quickly reactants decrease.
We will look at the reaction between marble chips (calcium carbonate) and hydrochloric acid.
As the reaction proceeds, the reactants lose mass because carbon dioxide gas is given off. We can measure the decrease in mass of reactants by using this type of apparatus with a conical flask stopwatch, cotton wool plug and balance.
Based on our measurements, we plot a graph of ‘mass of reactants against time’.
The rate of reaction at point A is given by the gradient at A which is y/x and the rate of reaction at point B is given by the gradient at point B which is y’/x’ .
Example for 2:
Instead of measuring the loss of mass of the reactant we can also measure the gain in volume of the product carbon dioxide.

This chemistry video tutorial provides a basic introduction into chemical kinetics. It explains how to calculate the average rate of disappearance of a reactant as well as how to identify the rate law expression using the initial rates method. It explains how to calculate the rate constant along with the appropriate units and how to calculate the initial rate of the reaction given the concentration of the reactants.

036 - The Rate Law
Paul Andersen explains how the rate law can be used to determined the speed of a reaction over time. Zeroth-order, first-order and second-order reactions are described as well as the overall rate law of a reaction. The rate of a reaction can be determined experimentally.

In electronic commerce, conversion marketing is the act of converting site visitors into paying customers. However, different sites may consider a "conversion" to be some sort of result other than a sale. One example of a conversion event other than a sale is if a customer were to abandon an online shopping cart, the company could market a special offer, for example, free shipping, to convert the visitor into a paying customer. A company may also try to recover the abandoner through an online engagement method such as proactive chat in an attempt to assist the customer through the purchase process.
Measures
The efficacy of conversion marketing is measured by the conversion rate, i.e. the number of customers who have completed a transaction divided by the total number of website visitors. Since conversion rates for electronic storefronts are usually very low, conversion marketing can be a useful way to boost this number, online revenue, and overall website traffic.
Conversion marketing attempts to solve the issue of low online conversion through optimized customer service. To accomplish this it requires a complex combination of personalized customer experience management, web analytics, and the use of customer feedback to contribute to process flow improvement and overall site design.
