Google & eBay
If you’ve seen a significant change in your Google search engine rankings over the past couple weeks, there’s a good chance you’ve been effected by Google's latest algorithm updates. One of the biggest impacts has been experienced by eBay which has seen an 80% drop off in Search Engine Traffic.
The motivation for Google to constantly adapt and improve its Search Engine Algorithm is to ensure they continue to provide the best search experience for the 6 billion daily user searches and stay ahead of their competition. This demonstrates that SEO can be very fragile when not deployed via a future-proof "content/user first" strategy.
