- Task
- Check where the person who clicked on the product ad actually ends up.
- Solution
- A sample of 150 random product addresses of the site map with verification of the response code of each, measurement of the response time of the main and the card.
- Result
- 50 addresses out of 150 (33%) returned 301, and all 50 led to a different position — a different size or color: 70B→70A, L→XL, white→black. In the scope of the directory, this is about 37 thousand addresses. For paid advertising, this is the most expensive defect found: the click was paid for a specific product, and the person sees another. Main gives the first response in 1544.6ms vs. 391.4ms on the card, no cache, with 118 images and none delayed. At the same time, the remarketing module transmits the Facebook product_id — the dynamic is technically possible, but it must be recorded on the cards.
