Amazon A9 is the name for Amazon’s search engine. The division that builds, does maintenance and makes improvements to the search engine is called the A9 division. They are a different company that provides “search engine and search advertising technology”. It is called A9 as a play on words of “Algorithms” as there are 9 letters after the letter “A”.

A9.com is a subsidiary of Amazon that develops search engine and search advertising technology. A9 is based in Palo Alto, California, with teams in Bangalore, Beijing, Dublin, Iași, Munich and Tokyo. A9 has development efforts in areas of product search, cloud search, visual search, augmented reality, advertising technology and community question answering.It considers keywords in deciding which results are most relevant to the search and therefore which it will display first.If you’re an Amazon seller (or aspiring to be one), you’ll need to understand the various ways to promote your products and Amazon page. But to make it more effective, you should tailor your promotional activities on Amazon based on how its algorithm works.

History of A9.com

A9 was created by Amazon.com in 2003 as an independent company aimed at producing technology for search and advertising. They moved into the building previously used by the DEC Systems Research Center in Palo Alto, California.Under the direction of its first president, Udi Manber, A9 focused on several areas, including the A9.com destination website, product search, and a search advertising platform. Some early A9 services such as “search inside the book” continued, while others have been discontinued. The A9 search engine powers product search for Amazon.com and several other eCommerce retailers.

In February 2006, Manber was replaced by David L. Tennenhouse as president. In September 2006, William Stasior, one of A9’s founders and a former AltaVista and Amazon.com executive, was named president. In June 2009, A9 acquired SnapTell, which developed smartphone-based visual search applications.

Stasior left in October 2012 to join Apple Inc. and work on Siri. Brian Pinkerton, who had developed WebCrawler in the 1990s, became general manager of A9 in 2012.

In 2019, after reporting from The Wall Street Journal revealed that Amazon had changed its search algorithm to favor more profitable products, Amazon took down the A9.com site and pointed the domain name to Amazon’s home page.

The Most Important Parts of Amazon Seller’s Product Listings

Amazon matches keyword searches against the information that seller provide for a product. Amazon Seller Central’s page on optimising listings explains. Sellers should include relevant keywords within their product listing title, product description, key product features bullet points and the backend search terms (the keywords hidden from customers that sellers can add to a product’s catalog data).Amazon provides a very simple-to-use interface where sellers can populate all the data relevant to their product.Once you know what to put in these fields, it makes it very easy to implement any changes.However, because A9 algorithm, frequent and unpredictable updates are a common point of frustration for many sellers on Amazon.

Seller should be more careful while updating their products.There are some factors which can help sellers to make their products in top rank in Amazon.

1. Product Title: Make a list of your most important keywords for your titles — including name variations that your customers are using (ex. “bedsheets and “bed sheets”). This doesn’t mean you should keyword stuff your titles. It’s a bad customer experience, and Amazon’s bots will likely catch on and suppress your listing.Number of Characters to include in title is for General 80–250, for Right rail ads 30–33 and forMobile: 55–63 characters. Capitalise each word of the title.Must include measurement like pound, inches, meters etc. Must use “and” keyword instead of using “&”. If its brand name then it’s okay to use it otherwise to use“and” is more preferable. Basic formula to make product title is:
   [Brand Name] — [Product Type] — [Feature #1] — [Feature #2] — [Feature #3] — [Size, etc.]

2. Product Features : Seller can use Merchant Tool to add keywords while adding Products. Product features are the second most important factor in surfacing your products. Number of Characters can be approximately 250. Typically, product features are formatted as a bullet point list as shown in the example below

Highlight the top five features that you want your customers to consider, such as dimensions, warranty information or age appropriateness. Begin each bullet point with a capital letter. Write in fragments and do not include ending punctuation. Write all numbers as numerals Separate phrases in one bullet with semicolons Spell out measurements, such as quart, inch, or feet. Do not write vague statements; be as specific as possible with product features and attributes. Do not enter company-specific information; this section is for product features only. Do not include promotional and pricing information. Do not include shipping or company information. Amazon policy prohibits including seller, company, or shipping information.

3. Product Descriptions : Product descriptions are typically several paragraphs long. They require detailed attention and some light HTML. If you’re selling products in a competitive or heavily regulated category such as health supplements, there are restrictions on what you can write. Make sure you read all requirements before you post your product descriptions. If that’s you, you may want to consider outsourcing this part. Do Hashtag research, when you place a hashtag before the main keyword. This allows you to get all the keywords that combine with the main keyword to form prefixes.

Amazon maintains a high standard when it comes to product information (as you saw in the sections above), so the integration between the two platforms features streamlined error handling to help identify specific product listing issues quickly and in easy-tounderstand terms.
