Welcome to the Q&A Forum

I'm working with a US client on the SEO for their large ecommerce website, I'm working on it from the UK. We've now optimised several of the pages including updating the meta-descriptions etc. The problem is when I search on the keyword iin the UK I see the new updated version of the meta-description in SERPs results. BUT when my client searches on the same keyword in the US they're see the old version of the meta-description. Does any one have any idea why this is happening and how we can resolve it? Thanks Tanya
