What are the criteria for selecting an efficient and practical crawler agent?
In the process of data collection, web crawler needs to visit the target website frequently to obtain a large number of valuable data information. However, using a single IP address too frequently may trigger the restriction mechanism of the target server, resulting in the failure to complete the data collection task. To solve this problem, crawlers usually choose to use IP proxies to hide the real IP address, so as to achieve a smooth data collection. Choosing the right crawler agent is the key to ensuring efficiency and practicality, here are some important factors to consider when choosing a crawler agent:
1. Agent response speed
Proxy response speed is the time it takes to access the relevant web page using the proxy, usually measured in milliseconds. In the large-scale data acquisition task, the agent response speed directly affects the efficiency and performance of the crawler.
An efficient crawler agent should be able to provide a fast response speed, so that the crawler can quickly obtain the content of the target page. When the crawler needs to access a large number of web pages, if the agent response is slow, then the whole data collection process will become very time-consuming and affect the work efficiency.
A fast response proxy server can greatly reduce the waiting time of the crawler, making the acquisition of data more efficient. Especially in the case of frequent visits to the target website, the fast proxy response speed can significantly improve the speed of the crawler and accelerate the progress of data collection.

In addition, fast agent response speeds reduce data collection outages due to timeouts or connection failures and improve data collection stability. When the proxy server response speed is slow, it is easy to timeout or connection failure, resulting in crawlers cannot obtain data normally, affecting the integrity and accuracy of data collection.
2. Agent survival time
The proxy IP has a certain lifetime, that is, the proxy IP is still valid for a certain period of time. For crawlers, it is very important to choose proxy IP resources with a longer survival time, because it means that the proxy server is more stable and can continue to provide effective proxy services for a longer period of time.
Stable proxy IP resources are essential for data collection tasks. When the crawler needs to visit a large number of web pages, if the proxy IP survival time is very short, it needs to switch the proxy IP frequently, which will increase the complexity and instability of data collection. Choosing a proxy IP with a longer survival time can reduce the frequency of proxy switching and improve the stability and reliability of data acquisition. In addition, the longer survival time can also reduce the maintenance cost of the proxy server. If the proxy IP has a short lifetime, the crawler needs to frequently re-acquire and validate the proxy IP, which consumes time and resources. Stable proxy IP resources can remain valid for a long period of time, reducing the workload of obtaining and verifying proxy IP addresses frequently, and reducing the maintenance cost of proxy servers.
3. Quantity and regional distribution
When choosing a crawler proxy, you should also consider the number of IP addresses and regional distribution of the proxy server. Choosing a proxy server vendor with a wide IP distribution and a large number of ips will provide more options and resources for data acquisition. A widely distributed proxy IP can simulate users in different regions and obtain more comprehensive data information.

4. Cost effectiveness
Proxy services usually require payment, so when choosing a crawler proxy, it is also important to consider its cost effectiveness. Higher quality agency services may require higher fees, but also provide better service and support. According to the specific needs and budget, choose a cost-effective proxy server provider.
5. Privacy and security
Crawler agents are used to hide the real IP address and protect the privacy and security of users. Therefore, it is crucial to choose a proxy server with good privacy and security. Ensure that the proxy service provider has strict privacy policies and security measures in place to protect users' data and information.
To sum up, the selection of efficient and practical crawler agents requires comprehensive consideration of agent response speed, survival time, quantity and regional distribution, cost effectiveness and privacy security and other factors. Only under the agent services that meet these standards can the crawler workers carry out data collection smoothly and obtain efficient, stable and safe data support.
2023-08-07 13:55:03Can I only buy proxies from a specific country?
Using 1 proxy costs 1 proxy balance and you can use 1 proxy from any country, state or city without limit!
2023-02-01 09:39:18Why I cant login to your software? Why the proxy is very slow?
All our servers are located in the US, What happend to you its possiblely because your network is unstable or your network has connection issue to the US, You can use a VPN which is fast & stable to the USA first before using lumiproxy and our proxy.
2023-02-01 09:38:59How long can I use the proxy?
When you used a proxy, it cost 1 proxy balance from your acct, its paid up to 24 hours of use time. But our proxies are residential proxies, Please understand the alive time for residential proxies is from a few hours to a few days which is normal.
2023-02-01 09:38:31Why your soft is detected by Antivirus? Is it safe?
Yes, 101% safe. Its just false positive detection from the Antivirus because the soft has features like changing the UserAgent, Screen Resolution and Referer. We tried to submit to them for whitelisting, but it takes time. Just close the Antivirus or adding our soft into its whitelist manualy.
2023-02-01 09:38:09When I change a new proxy why my browser or soft is auto closed?
In "Settings" tab, Unselect "Auto close program when change proxy"
2023-02-01 09:37:45Is there any way that the target website can trace the origin to us?
No, we secure the traffic at the IP level. Traffic to websites originates at residential IP addresses that are not associated with your company or your location. All traffic is also encrypted. You are responsible to secure every other part of your system.
2023-02-01 09:37:10What are residential proxies used for?
You can theoretically use residential proxies for anything a regular proxy is capable of. The undetectable nature of residential proxies makes them ideal for media streaming, online shopping, and data scraping on sites that block normal proxy usage.
2023-02-01 09:36:34How long does it take to receive the proxy balance or get my new account activated after the payment?
If you paid by other payment methods than Bitcoin, you should get it instantly after the payment was made. If you paid by Bitcoin, you need to wait until the transaction has 1 confirmation from the Bitcoin network, for how long it takes to get 1 confirmation it depends on the Bitcoin network and the Miner fee you paid.
2023-02-01 09:35:50Do you provide trial or payment refunds?
We do not provide trial, you can order the smallest package to test. We do not make the refunds for any paid services. Please be aware that all payments are final. If you think the proxies or the software are not working correctly, We are always here to help you solve your problems. Thank you.
