Anyone can tell me whether is there a way telling site is fully optimize or no? If there is a way, please let me know. Thanks
Best can be always made better, there is no way that you can come to know that your website is fully optimized or not, yes, you can come to know, whether it is poorly optimized or well optimized.
You cannot know if your site is fully optimize because you should have a great result before you can know that.. Just always optimize it and see if you are improving..
it can see in your Analytics results. if your website optimized then you can see better results otherwise you will find negative results.
