Walmart is a household name around the country and for a good reason. It is home to anything and everything that you could possibly need. In recent developments, Walmart has decided to branch out on the online front looking into generating more traffic selling and distributing products on Walmart.com. 

Currently, Google still holds the largest ad market share in the United States. However, Amazon's market share is growing at a remarkable rate and is expected to dominate even Google only in a few year's time, as reported by the new eMarketer forecast. 
​
Amazon's advertising business has grown at an alarming rate over a few years. With its online ad business going up to 37%, making it $3 billion in the second quarter, and its digital ad business increasing up to 8.8% in 2019 from 6.8% in 2018 of the US's total digital spend. Amazon is now a contender of Facebook and even Google.  

If you are a regular customer of Amazon, you would know that if you search for a product on Amazon, you get multiple results, including products that are not even relevant. The search algorithm of the website has always been a complete mess. 

However, just recently, Amazon made some changes to its search algorithm. You might be thinking that the search will now be as per the relevance of the products, but unfortunately, it’s not. The search algorithm is now based on which of the products selling through Amazon would make Amazon more profit.
