This piece goes alongside our web design and SEO work.
Do you know how current the code is in the JS, CSS and HTML files a web page uses? As browsers update over time, old coding structures can stop working or start behaving differently. In our SEO work we noticed that the standard tools, and the assumptions we reached through our own observation, were not giving us enough data; something was being missed. That something was how current the CSS and JS files themselves were.
We came to think that judging the quality of a website by page speed, content quality and its feature set was not enough to read it properly. Not long ago one of our clients told us their website had just been built and was up to date, and we found that the code on the site was not modern at all. We reported it. The libraries in use were extremely old, and that is when we decided to turn this into an automatic tool and call it Sitelab.
Try it: turksem.com/sitelab
Sitelab is an analysis tool. For page speed data on your site, go to the pagespeed change page.
The Hidden Danger on Your Site
Your site can look fast in the analysis tools and be excellent on that first connection. Once a user starts actually using it, though, they may run into problems. Understanding that with a tool is very hard. So we focused on those hidden problems and put this in front of site owners free of charge. It is the ideal way to solve that hidden problem on their sites.
The tool finds every internal and external .css and .js file on the site, opens a separate connection to each and downloads them to our server. We then examine the code inside those files one by one and find the date the code was written. That is how you can discover your site’s libraries on turksem.com/sitelab.

Sitelab Is Live in English
Because our site analysis tool is so complex, we unfortunately ran into problems while building its multilingual structure. The Turkish integration did not work out. Since the inner voice of the system is English, constructing a different language structure became extremely difficult. For that reason we have published it in English for now, and we will bring in Turkish and the other languages later.
In terms of what it does, Türk SEM Sitelab puts data in front of users that they will not find elsewhere. We can say our tool is unique in the world in its own field. We will keep developing it according to how it gets used and carry out even broader analyzes. For now we separate the code into three periods, Legacy, Transitional and Modern, but in future versions we plan to split it into 5 or even 6 separate periods. We will publish these improvements and additions on the Version page.
