It is easy to see that the decline in both organic and paid traffic had a negative impact on sales. After the settings were optimized, traffic gradually began to recover, but it took some time to return to its previous levels.
The bottom line
The negative impact is best illustrated by Google Analytics data. The language was changed on January 15, and the original settings were restored on January 29. To clearly demonstrate the decline in traffic and sales, we compare the data from January 15 with the data from January 23 — one week after the language change.
Comparing January 15 and January 23, organic traffic dropped by half.
Organic traffic
The decline was even more significant for paid traffic: it dropped by 3.1 times.
Paid traffic
The number of orders decreased eightfold.
Sales
When it comes to sales, the situation was as follows. Sales from paid traffic dropped by 7.1 times, while sales from organic traffic decreased by 2.3 times.
