Here are a few more to consider adding:
Thanks for this list but can anyone please explain by adding all these URLs in WP-Rocket URLs to prefetch. How can it help our website? Is it safe? Or How it will help I tried it on my website and still page speed loading is very low. Please guide me if possible Thanks
Hi there, Should I copy-paste the list on the website even if I do not use those websites at all. For example, in the list, I do not use this service at all //s3.buysellads.com
So should I still add this URL in the list or do I have to cherry-pick from the list?
Or if I can copy-paste all the list it will not affect the performance? I am using the whole list on my own website https://www.khalsa-website-designers.net/ but I do not know if enabling or disabling effect on the performance and if I should copy-paste the full list given above or should I only copy-paste the services I use.
Hi brother Lukecav, Thank you very much. I have checked that website page test .org website and I found the list of domains I should add. Here is the screenshot = http://prnt.sc/sov9vv
But I have another question now. The question is that do I have to add these lines before the domain //
Hello brother Lukecav. You have helped me to get this issue nearly solved and those who had questions like me they will get the help for the lifetime from this post and comments.
Brother one last question. What about those domains which have www. before the domains?
Should we be adding these domains like this:
or like this:
Thank you in advance.
Only use the external site URLs that are being requested on your site and no it will not slow your site down, the idea is that the DNS requests that are external will be prefetched for the site user.
Brother Lukecav, Your replies are helping people like me who did not know anything about DNS Prefetching. Brother, I want to as you a question and this question may be hitting others mind too.
Let's say I have added nearly 8 domains in the Prefetching. When a user visits the website for the first time. Will all of those 8 domains affect the logging time for the first time user? I mean if someone is visiting for the first time from his device then do you think it will take nearly 1-3 seconds time to Prefetch the DNS for those domains as well and that will make the site slower for the new user?
Or does it work like this --> The user came for the first time. Once the full website is loaded then the browser sends the command to prefetch DNS for all the links on the page.
Another question related to this question:- I always add my website link in the footer of all the websites I create. For example, you can see here https://bestandcheapbondcleaning.com.au/ so on this best and cheap bond cleaning website should I add my domain in the prefetch DNS section too?
lukecav - I hope that you or someone else in this forum may be able to clarify this for me. I added //soundcloud.com to my dns prefetch list. I am still having issues (see attached file) Should all these be added too: //wave.sndcdn.com, //w.soundcloud.com
I also came across code.ionicframework.com when running a test - should this be added to my prefetch list as well?
Any feedback would be greatly appreciated!
First of Fall thanks to lukecav for this amazing list of DNS Prefetching list that includes all the latest domains that are used on almost all websites and reduces server response time on our website. I am currently using this list of my website and I've seen many other websites using preconnect now these days. what that means is it better than DNS prefetching.
