SERP + competitor scrapers getting flagged

SharkyDarky · Monday at 10:11 AM

I run scrapers to pull ranking data and competitor pages at scale and it's gotten rough, a lot of targets flag the scraper as a bot within a handful of requests now, even on residential IPs. Just trying to keep a data pipeline alive without babysitting it.
Is it the headless-browser signals giving it away, request pacing, or the TLS/fingerprint side?

Feel your pain bro. My scrappers ball hard also. Always assuming its tls handshake screwing my shit up......Try rotating tls fingerprints as well as ips?

It could be a combination of factors rather than one issue many sites have improved bot detection so even legitimate data collection gets flagged
Have you noticed whether the problem is consistent across different websites or only specific platforms?

In my experience, it's usually a combination of request patterns and browser fingerprinting rather than just the IP. Slowing the request rate, rotating sessions naturally, and respecting crawl limits tends to improve reliability morre than focusing on a single factor.

From what I've noticed it is usually a combination of factors rather than one specific thing sites seem to be getting much better at detecting automated traffic so even setups that worked before can get flagged now it feels like this has become much more common over the past year.

Ye you are totaly right ... It seams a combination is the key... For your question about site wide consistency I noticed it bout more frequent on sites using Cloudflare and those doing aggressive bot detection with javascript . What kind of JS tricks u guys got that really screw scrape ?

From what I've seen, it's usually not just one thing. Modern bot detection looks at a combination of signals—browser fingerprints, TLS/JA3 fingerprints, request patterns, cookie behavior, JavaScript execution, and IP reputation. Even residential IPs can get flagged if the overall behavior looks automated.

Honestly at this point my scraper gets made as a bot faster than I get made at family gatherings. Nine times out of ten it's the TLS fingerprint giving me away, not the IPs — a shiny Chrome user-agent riding a Python handshake is basically wearing a "hi I'm a robot" name tag. What target are you hitting, and is it flagging you on the first request or only once you speed up?

Residential IP alone wont fix it. If the browser fingerprint, TLS and request pattern are the same, changing IP just gives them another signal to connect.

I would slow it down first and test with a normal browser profile. Also check if the residential provider is giving you repeated or already abused IPs. Some pools look big on paper but the same IPs come back very often.
