My website is hosted in Texas and the top-level domain is ‘.in‘, so I always try to optimize the website so that Indian visitors can open it within 5 seconds. Everything was perfect and my website was taking 4-4.5 seconds to open from India. I had tested the speed of my website using webpagetest and dotcom-tools. After adding the tracking code of whos.amung.us, I tested my website again using webpagetest. This time webpagetest showed 10+ seconds to open the website from India. I was perplexed by the response time of the website. I thought something went wrong with my VPS, so I asked my hosting company to look into the issue. They did not find any issue and told me that the problem might be in the application codes.
The following two screenprints are with whos.amung.us code:
If you look at the above connection view, you will find that there are about 25 domains that were called by whos.amung.us code. The DNS lookup and data retrieval from these additional domains increased the response time of my website from 5 seconds to 10+ seconds.
The following two screenprints are without whos.amung.us code:
There is no call to those domains after removal of whos.amung.us code and the website was fully loaded in 4.5 seconds.
I have written this post just to help other webmasters who are using whos.amung.us code. Check the response time of your website on webpagetest.org and if you see suspicious websites in the details, it is time to remove whos.amung.us code from your website. The speed of the website is one of the most important criteria for search engine ranking, so webmasters must not overlook it.
