Hi ALL,
first of all Shopify stopped to use Lighthouse to calculate the speed score, this is why the sudden drop of speed score in Shopify in comparison with Lighthouse or Xmetric.
Now the why: some developers do ZERO work on performing your store, they only add a hacking code that detect speed checkers. When it detect speed checkers, it serve an empty page, with no content. That’s why your Lighthouse or Xmetric speed score it is so high. Now that Shopify stop linking its speed report with such speed checkers, the scam it become clear to all.
The code contain such lines document.write / document.open and are inserted in the theme.liquid (use ctrl+g to locate them). If you find such lines, you been scammed.
I suggest everyone who got this scam to reply to my post here and add the name or data of the developer to help others to do not fall in the same scam.
My scammer was hired on Fiverr:
It is taking 2 weeks of work and lot of money to fix this issue. Cause it also damage how the store works.
Please everyone, spread the voice as much as possible because Shopify still did not made any official statement on this, and many store owners have no idea at all about this.
Let’s make sure those scammers get banned and get no more money from store owners.
