Avoid Multiple Page Redirects
According to Google's PageSpeed Insights, redirects trigger an additional http request response cycle which delays page rendering.
For example, when a mobile user visits your url (ex. webpage.com), but your site redirects them to a mobile mobile url (m.webpage.com), that will slow page load. In some instances, sites may redirect to www.webpage.com and then to m.webpage.com, increasing the number of redirects issued and slowing mobile usage to a near halt.
Reducing unnecessary redirects
Oftentimes, eliminating redirects can be done without changing the operation of the page.
The best advice is to immerse your site in responsive design. This can ultimately lead to one trip to the landing page with no redirects.
