What's so hard about G2 comment crawler development?
Engaged in data crawling old iron know, G2 this kind of platform anti-climbing mechanism than the cell gates are still strict. If you directly fight hard, you will be lightlyIP blockedIf it is not, the whole project will be paralyzed. Last week, a SaaS friend complained that they manually changed the IP five times or be recognized as a robot, angry technical brother almost smashed the keyboard.
Proxy IP is the key to breaking the mold
Trying to glean data from G2 and not get caught is at the core of two things:The server won't recognize you as the same person.(math.) genusMake access behavior look like a real personThe first thing you need is a proxy IP to play with. That's when you have to rely on proxy IPs to play with - as if you were playing a game of chicken and kept changing your landing site so that your opponents couldn't figure out your route.
| Program Comparison | Free Agents | ipipgo proxy |

| success rate | 30% or so | >95% |
| Degree of anonymity | Transparent Agent | High Stash Agents |
Four steps to build a stable crawler system
1. The IP pool should be wild enoughThe dynamic residential proxy with ipipgo automatically switches to a different city IP for each request, which is 10 times safer than using a data center IP. Tested with their U.S. + Germany mixed node, continuous capture of 500 pieces of data did not trigger the wind control.
2. There's something to be said for rhythmic control.Don't click like a hungry wolf. Set it.3-8 seconds random, mimics human browsing speed. There's a higher success rate for screwing around from 1 a.m. to 5 a.m. Don't ask me how I know that.
3. The request header should be able to disguise: User-Agent don't always use Chrome, put Firefox, Edge and these in turn, remember to remove the feature with the word Python.
4. Exception handling can't be understated: Stop immediately when you get a 403 error, switch IPs and cut in from another portal disguised as a new user. ipipgo's API automatically assigns new IPs in 5 seconds, much faster than switching manually.
A practical guide to avoiding the pit
- Don't write dead IP addresses in your code, use theProxy Pool PollingOtherwise, you'll have to change your IP address.
- Don't be hard-headed when it comes to CAPTCHA, it's less stressful to go to a coding platform than to build your own recognition model.
- Crawl paths are updated weekly, and G2's anti-crawl team is no slouch!
Frequently Asked Questions QA
Q: Why is it necessary to use a high stash proxy?
A: Normal proxies will expose the real IP, just like wearing a mask without covering your nose - for nothing. ipipgo's high stash mode will wash out all this X-Forwarded-For header information.
Q: How much IP volume is needed per day?
A: Depending on the size of the business, startups are advised to buy 5000IP/day packages. ipipgo's traffic packages can be stacked on demand, and use over automatic suspension without burning money.
Q: How do I get first aid if my IP is blocked?
A: Immediately deactivate the IP for at least 6 hours and use the ipipgo backend of theIP Health Detectionfunction to kick suspicious IPs out of the whitelist.
In the end, the proxy IP is well chosen, and the crawler gets off work early. With ipipgo's elastic IP service, it's equivalent to installing a proxy IP for the crawler.teleportation skillG2's anti-climbing system can't figure out your movement track at all.
