How Does This Alternative Engine Affect Primary Search Engines?

Amazon is one of the strongest domains on the Internet. As such, its pages rank for an enormous number of search queries. Combine this with the fact that these pages are highly optimized for selling and you can see their incredible value.
If it makes sense for your or your client’s business model, it is a good idea to point relevant links to given Amazon product pages to help bolster the strong domain authority to make the page outrank your competition.
You may also want to look into leveraging Amazon’s platform for selling your or your client’s products rather than creating your own website. Though this will likely cut into margins, it may prove worthwhile in some cases.
Amazon can help some companies with reputationmanagement problems. If your company or product is plagued by negative sites populating the SERPs for product-based queries, a strong Amazon page will be a strong competitor to pages that disparage your product.
