As you already might know, certain sites do their best to prevent automated tools (like Price2Spy) to monitor their prices. Tdotperformance.ca is Canada’s largest source of car performance parts and we have monitored this site for our clients for years, but recently this site has been putting in a lot of effort in preventing web-scraping tools like ours.
After we have exhausted all classic ban-avoiding techniques, we have resorted to our strongest weapon – Stealth IP.
(Why do we turn to Stealth IP only as a last resort? The reason is simple – this type of IP traffic is very expensive, and may cause additional costs for clients who are monitoring many URLs on such sites. That is why we keep trying conventional IP methods till we feel we have exhausted all available possibilities – and that’s when we turn to Stealth IP traffic.)
