Dartera contacted us with an offer for a free audit. At first I was very skeptical, but after our conversation with Dartera, the added value could no longer be overlooked. I look forward to working with you and thank you for the free preliminary work!

Amazing Service! Great passion and very SMART!

Spammer and scammer. Pretended to spend 6 hours over 3 days on an analysis "worth" 2'800 CHF, on a small static site that had 3 pages, one of them a simple contact form. Pretended that they could optimize a page that loads in under 700 ms, by saying it loads in 2.2 seconds and they can make it load in under 1 second. Keep away, go to serious companies and not someone who employs such tactics to try to scam people who are slightly less knowledgeable on the topic. Post reply edit: Owner admits in reply that "there has been no prior collaboration between us", I did not request this, they randomly spammed this, no 6 hours at a 460+ CHf hourly rate effort was done. Audit was teased, and not shared (prior to this review, which magically made them try to share it, but also only the "light" version). Even that contains everything free tools already give you, and even better and in more details then this fake audit. A 2.2 MB image which is indeed not optimized and wasn't meant to be either (the whole page is a placeholder) can be downloaded with about 25MBit/sec in under 700 ms, a bandwidth easy achieved even with mobile devices here. Again, showing either their utter lack of knowledge on the topic, or knowing this well and trying defraud less knowledgeable customers.
