Nevertheless, their utility depends on the info source characteristics, job scale, required elements’ type, and more.\u003C/p>\r\n\u003Cp> \u003C/p>\r\n\u003Ch3>\u003Ca name=\"anchor2\">\u003C/a>1. Give new browser automation tools a try\u003C/h3>\r\n\u003Cp>Selenium has served as a versatile information gathering tool for almost two decades. Its high user actions’ emulation abilities come with slow, resource-hungry online page processing and require substantial programming knowledge. Puppeteer is great at running concurrent tasks and is often unsuitable for acquiring insights with methods not involving JavaScript and Chromium-based browsers.\u003C/p>\r\n\u003Cp>\u003Ca href=\"https://dev.to/wisdomudo/the-ultimate-guide-to-scalable-web-scraping-in-2025-tools-proxies-and-automation-workflows-4j6l\" target=\"_blank\" rel=\"noopener\">Scraping experts recommend choosing browser automation software considering new solutions.\u003C/a> Playwright is faster than the developments mentioned above due to isolated browser contexts, and implements useful features for HTML handling by default, including autowaits, custom selector engines, persisting in authentication state, and more. After a team buys residential and mobile proxies, these IPs are implemented with Playwright easily via browserType.launch and configured in Python or Node.js.\u003C/p>\r\n\u003Cp> \u003C/p>\r\n\u003Ch3>\u003Ca name=\"anchor3\">\u003C/a>2. Choose an HTTP client according to goals\u003C/h3>\r\n\u003Cp>Preferred language and programming skills level, webpage type, budget and objectives scale are among the factors determining the choice of an HTTP client. Python’s killer features for scraping make its urllib3, requests, httpx, and aiohttp libraries relevant for most tasks.\u003C/p>\r\n\u003Cp>Ruby’s fast requests processing, Ruby on Rails technology, and SSL verification make Ruby HTTP clients (Faraday, Net::HTTP, HTTParty) suitable for large amounts of information. And using Java for web data harvesting through HttpURLConnection or HttpClient seems logical for multithreading projects. Keep in mind that the chosen HTTP clients base on different SSL libraries and require different TLS parameters.\u003C/p>\r\n\u003Cp> \u003C/p>\r\n\u003Ch3>\u003Ca name=\"anchor4\">\u003C/a>3. Prepare the scraping session\u003C/h3>\r\n\u003Cp>Those who prepare to collect crucial online insights \u003Ca href=\"https://dexodata.com/en/residential-proxies\" target=\"_blank\" rel=\"noopener\">buy residential IP addresses\u003C/a> to act as a regular visitor, not an automated algorithm. Experts recommend other same-purpose measures before running requests to HTML server:\u003C/p>\r\n\u003Cul>\r\n\u003Cli>Change the User-Agent header to present info retrieving actions as an end-user device.\u003C/li>\r\n\u003Cli>Set up all possible cookies on your side instead of rely on dynamically generated parameters on servers. These are geolocation, Accept-Language, Referer, etc.\u003C/li>\r\n\u003Cli>Reuse session parameters for headers and cookies configurable on client side (e.g. system language).\u003C/li>\r\n\u003C/ul>\r\n\u003Cp>Experts sometimes do that in headless browsers and transfer parameters to more lightweight browser list scripts.\u003C/p>\r\n\u003Cp> \u003C/p>\r\n\u003Ch3>\u003Ca name=\"anchor5\">\u003C/a>4. Apply DevTools\u003C/h3>\r\n\u003Cp>\u003Ca href=\"https://developer.chrome.com/docs/devtools?hl=ru\" target=\"_blank\" rel=\"noopener\">Chrome DevTools\u003C/a> and its analogs provide technical information on sites and elements experts are going to work with. Here is what the distinct DevTools tabs are useful for:\u003C/p>\r\n\u003Col>\r\n\u003Cli>Network — to check requests and responses, copy the parameters of the root request through cURL using cURL–string conversion, and apply obtained details to your script.\u003C/li>\r\n\u003Cli>Elements — to inspect trees of HTML elements on an internet page (text, tags, attributes). This concerns elements added dynamically via JavaScript. Data harvesting expert identifies the particular units and copies HTML selectors through the “Elements'' tab. Also, integrated DevTools search helps in finding the JS-based paths, understanding the order and specifics of dynamic content’s loading.\u003C/li>\r\n\u003Cli>Sources — to detect target objects for further retrieval, including JSON objects. The limitations include dynamic content which can not be seen in the section but is available through HTTP clients.\u003C/li>\r\n\u003C/ol>\r\n\u003Cp>Instead of using Chrome DevTools for a requests’ modification, one can leverage Postman as well.\u003C/p>\r\n\u003Cp> \u003C/p>\r\n\u003Ch3>\u003Ca name=\"anchor6\">\u003C/a>5. Prefer API whenever possible\u003C/h3>\r\n\u003Cp>Discussion on what is better for scraping, API or HTML, is still in trend. The decision depends on the project specifics, as well as the choice, whether to buy residential IP pool access betting on the NAT technologies or strive for faster and more sustainable datacenter proxies.\u003C/p>\r\n\u003Cp>API is usually faster and requires less data packets to send and receive for a result. So harvesting web information through API is preferable from the expert’s point of view.\u003C/p>\r\n\u003Cp> \u003C/p>\r\n\u003Ch3>\u003Ca name=\"anchor7\">\u003C/a>6. Run two and more processes concurrently\u003C/h3>\r\n\u003Cp>First data mining phase brings raw HTML-formatted content which needs to be processed and converted to JSON output, convenient for further exploitation. Parsing here is an act of extracting needed info from HTML and includes two more stages:\u003C/p>\r\n\u003Col>\r\n\u003Cli>Reading files\u003C/li>\r\n\u003Cli>Using selectors to get only crucial pieces of knowledge.\u003C/li>\r\n\u003C/ol>\r\n\u003Cp>Choosing a web parser, keep in mind that BeautifulSoup with CSS selectors suitable for most occasions. lxml with XPath does everything CSS selectors can and even more, which includes traversing up the HTML tree and the conditionals’ use.\u003C/p>\r\n\u003Cp>Extract the publicly available insights and process them simultaneously. The Asyncio library in Python helps running a single parsing procedure and up to nine data collection moves simultaneously. Scraping experts focus on the following nuances:\u003C/p>\r\n\u003Cul>\r\n\u003Cli>The best proxies for target sites support dynamic IP change through API methods and concurrent requests’ sending.\u003C/li>\r\n\u003Cli>Some processes may be stored in a buffer for further processing.\u003C/li>\r\n\u003Cli>Apply both external and internal queues to coordinate actions beyond single containers or environments. With the queue it is easier to monitor algorithms, and the choice of a queue system (e.g. RabbitMQ or Kafka) depends on the number of applied applications or services.\u003C/li>\r\n\u003C/ul>\r\n\u003Cp> \u003C/p>\r\n\u003Ch3>\u003Ca name=\"anchor8\">\u003C/a>7. Use more ethical proxies \u003C/h3>\r\n\u003Cp>Scraping experts buy residential and mobile proxies to distribute the load on servers and provide them with numerous unique IP addresses sending requests. The more original IPs are involved, the more information is available before the web page decides to refuse queries. \u003Ca href=\"https://dexodata.com/en/blog/why-use-residential-proxies-for-data-harvesting-5-arguments-from-a-trusted-proxy-website\" target=\"_blank\" rel=\"noopener\">Geo targeted proxies not banned by target sites provide actual knowledge on local context or metrics.\u003C/a>\u003C/p>\r\n\u003Cp>Ethical ecosystems for raising data analytics level strictly comply with \u003Ca href=\"https://dexodata.com/en/blog/ethical-proxies-a-faq-from-proxy-ecosystem\" target=\"_blank\" rel=\"noopener\">AML and KYC \u003C/a>policies to:\u003C/p>\r\n\u003Col>\r\n\u003Cli>Assist in getting reliable and accurate info\u003C/li>\r\n\u003Cli>Restrain from affecting target sites’ performance.\u003C/li>\r\n\u003C/ol>\r\n\u003Cp> \u003C/p>\r\n\u003Ch3>\u003Ca name=\"anchor9\">\u003C/a>How to collect web data like a pro with Dexodata?\u003C/h3>\r\n\u003Cp>Extracting business insights from publicly available HTML content at scale requires preparation.
