Hello, my site is pretty dang slow and I don't know how to administer the recommended changes. Is there an easy fix for any of these? My indexed URLs recently went from 70k down to 30k and I believe that speed could be one of the reasons as to why.
-Parallelize downloads across hostnames
-Combine external CSS
-Serve static content from a cookieless domain
-Leverage browser caching
Look forward to any type of feedback/solutions!!!!
Speed may definitely be an issue there. Studies show that 53% of visitors abandon a page if it doesn't load on 3 seconds (on mobile!), so that may very well be your case.
What you described sounds like something that you can easily fix. It's just a matter of finding the right way to access your files and make some adjustments. << Snipped >>
