Welcome to the Q&A Forum

Thanks, yes I had read this article but can't find any websites using this technique. Has it been adopted as an industry standard, or is there another option?

Is delivering scaled images using srcset a good idea?

Thinking of delivering one image size to Mobile and another to Desktop. How can I do this for all browsers?

Thanks Mike

To preserve link juice should I "nofollow" links to about us and contact us pages that appear at the top of our navigation?

I read this article - but I am not familiar with the authenticity:

thanks - yes page speed has declined and I'll look into this
First Byte Time (back-end processing): 79/100
Leverage browser caching of static assets: 75/100
Both of these were over 90% before the inclusion of Live Chat.

For the last week we have hosted Live Chat on www.freedomltd.com desktop and tablet.

The latest MOZ ranking reports shows 4 increase, 86 decrease and 170 unchanged keywords.

Could Live Chat have anything to do with this?
