SEO brothers look over! Free Proxy Crawler without IP Blocking!
What's the biggest headache of doing website optimization?Crawlers definitely rank in the top three for blocked IPs.The first thing you need to do is to get the crawler to run on the target site! Hard-written crawler scripts, running on a break, or it is the target site blacklisted. Today, we will give the guys a trick, with the proxy IP this artifact with a free crawler tool, directly doubling the efficiency of SEO data collection.
I. Why is your crawler always blocked?
A lot of newbies tend to make a mistake--Use your own computer's IP to dislike it.The first thing you need to do is to visit a certain website 50 times in a row. For example, even visit a website 50 times, people's servers can immediately recognize the anomaly. Here is a real case: my friend last year to do e-commerce competitor analysis, single IP crawl data, the results of three days on the blocked 7 server IP, delayed the double eleven preparation period.
| the act of committing suicide | correct posture |
|---|---|
| Single IP High Frequency Access | Multiple IP Rotation Requests |
| Fixed User-Agent | Random request header |
| No visit interval | Dynamic Delay Setting |
Second, how did the proxy IP become a lifesaver?
Proxy IPs are, to put it bluntlyMasking the ReptilesIf you are not a good person, you will change your identity every time you visit. It's like going to the supermarket to try out food, if you always wear the same clothes, the clerk would have recognized you. Here I would like to emphasize the service of ipipgo, they have a particularly useful function - theDynamic IP pooling with per-minute billingThis is especially suitable for crawler scenarios that require high-frequency IP switching.
import requests
from itertools import cycle
API extraction link for ipipgo (remember to replace your account)
proxy_api = "http://api.ipipgo.com/getproxy?format=text&count=20"
proxy_list = requests.get(proxy_api).text.split('')
proxy_pool = cycle(proxy_list)
for page in range(1,100): proxy = next(proxy_pool)
proxy = next(proxy_pool)
try: response = requests.get()
response = requests.get(
url=f'https://目标网站?page={page}',
proxies={'http': f'http://{proxy}'},
timeout=5
)
print(f'Page {page} captured successfully')
except.
print(f'{proxy} failed, automatically switching to next')
Third, how to choose free tools do not step in the pit?
There are a variety of free tools on the market, but many of them have dark pits. It is recommended to focus on these points:
√ Support for customized request headers
√ Ability to set random delays
× Use caution if registration is not required(Many will sell user data)
Here's a recommendation for a program I'm using myself:Python + Scrapy framework + ipipgo proxy pooling. You have to write a bit of code, but it's super flexible and you have all the key data in your hands.
IV. QA time (a must for newbies)
Q: Do free proxies work?
A: Temporary test can be, long-term use is recommended on the paid. Before using free IP to crawl data, 8 out of 10 do not respond, in turn, delaying things!
Q: How often does ipipgo's IP change?
A: They are divided into two modes: dynamic IP is changed once per request, and static IP can last for 1 hour. If you are doing SEO, it is recommended to choose the dynamic one, which is not easy to be recognized.
Q:How many IPs do I need to allocate for crawlers?
A: There is a simple formula:Requests per hour ÷ Number of requests allowed for a single IP. For example, if a site is limited to 50 times per hour for a single IP, and you want to climb 500 times/hour, you need at least 10 IPs in rotation
V. Guide to avoiding the pit (blood and tears experience)
I stepped on a big mine last year while helping a client with local SEO optimization:Used an IP from an unreliable proxy service provider.The result is that the data crawled is all cached pages from competitors' websites. Later changed to ipipgoCommercial level agentsIt was only solved by the fact that their home has a dedicated web crawler channel that responds more than twice as fast as a normal IP.
Final rant: doing SEO data collection is like fighting a guerrilla war.IP is your bullet.The right proxy service provider can really do more with less, don't save a little money on tools. With the right proxy service provider can really get twice the result with half the effort, don't save a little money on tools to delay the big event. What do not understand can go directly to ipipgo official website to find online customer service, their technical staff is quite professional, according to the specific needs of the recommended IP package.
