Things to consider when evaluating web scraping service providers

Let’s dive into the most critical factors to analyze when choosing a reliable crawler service.

Features and tools

Service providers typically offer several crawler tools, each with its own unique features and characteristics. You need to choose the right tool based on your specific use cases and needs. Here are some tools typically provided by these services:

• Browser extension: Plug-in that allows users to directly retrieve data when browsing websites.

• Desktop application: an independent application with a user-friendly interface for configuring and running crawler tasks. Typically no-code or low-code tools.

• Crawler API: A set of endpoints with data retrieval capabilities that can be integrated into any web application or workflow.

• Crawler browser: A graphical user interface or headless browser designed specifically for web crawlers.

• Crawler IDE: Provides tools for developers to easily build and manage data retrieval scripts.

• Crawler SDK: A library that can be used in multiple programming languages so that the functions of the service can be accessed directly in the program code.

Depending on the tool you choose, you will have access to the following features:

• Anti-bot bypass: Technologies and mechanisms to avoid detection and blocking by anti-bot measures.

• Proxy integration: Anonymize HTTP requests and protect your IP. For more information, see our in-depth proxy IP type guide.

• JavaScript rendering function: Execute JavaScript code when rendering the target website, access dynamically retrieved content and pages rendered by the browser.

• Automatic data conversion: Built-in options for preprocessing, formatting, and converting crawled data into the required output format.

These elements play a vital role in improving the efficiency, flexibility and effectiveness of data acquisition efforts. Choose a service provider that offers tools and features that match your crawler goals and needs.

Customization and flexibility

A good service should provide the option to retrieve material from any website, regardless of its layout or structure. This is what customization means. You should not be limited by the limitations imposed by the tool. Instead, you should be able to integrate them into your crawler process and use them on any website.

In other words, service providers need to ensure a high degree of flexibility. Its services should not be limited to a few popular websites, layouts or scenarios. Unfortunately, this usually happens with free options or companies new to the market. That's why it's best to avoid these services.

Please remember that the website is constantly receiving updates and layout changes. Choosing a service provider that suits your current needs doesn't mean it will always be right for you. Switching to a competitor will cost you time and money and should be avoided. So try to make decisions that are feasible for the future. Consider aspects that are not currently a priority but may soon become a priority.

Cost and pricing plans

By understanding a data capture service provider's pricing structure, you can determine the value of their services. Here are some common pricing plans:

• Free plan: has limited functions and capabilities, targeting small-scale or occasional crawler needs.

• Value-added plan: combines free and premium features. You can access basic features for free, but premium features or support require payment.

• Pay-per-use plan: Charges are based on actual usage of the service. Charges are usually based on the amount of data crawled or the number of requests.

• Subscription plan: Pay a fixed monthly or annual fee and get a pre-defined set of features. Subscription levels are typically defined based on the number of requests or data traffic usage.

• Enterprise plan: A pricing plan tailored for large-scale crawlers. Often includes dedicated support.

Consider the balance between cost and value provided by the service provider and make sure its pricing fits your budget. To do this, evaluate factors such as data volume, required functionality, and support options. Also be aware of hidden costs, such as overage fees or support fees.

Look for companies that offer free trials to test their tools before committing to a paid plan. This way, you can make sure they meet your needs. A refund policy is also an added layer of security since you can get your money back if you're not satisfied.

Data quality

Some companies not only provide web crawling tools, but also sell ready-made datasets or create datasets on demand. The crawled data forms the basis for multiple decision-making processes and business strategies. This is why high-quality data is so important.

Poor data quality can lead to false insights, incorrect conclusions, and ineffective decisions. It can negatively impact various aspects of your operations, including market research, competitive analysis, and pricing strategies.

A trustworthy provider should ensure high-quality data recovery through its features. These functions should include data validation, cleaning, and formatting capabilities to eliminate inconsistencies, errors, or irrelevant information.

Research the vendor's track record and reputation for data quality before making a decision. Look for testimonials or case studies that prove it consistently delivers high-quality data. You can also request a sample data set to evaluate the status of its data extraction process.

Reliability and stability

A reliable web crawling service prioritizes continuous uptime and high availability. This requires a robust infrastructure with redundant systems to minimize downtime and advanced technology for heartbeat monitoring.

To evaluate performance, use the free trial period to conduct various tests. Factors to consider include connection speed, response time, and API and proxy success rates. Additionally, explore its customer reviews on Trustpilot and G2 to gain valuable insights into other users’ experiences. Choosing a service provider with a track record of reliability is crucial as this directly affects the efficiency of their services.

Scalability is another key aspect. Ensure that the service provider can effectively handle different levels of traffic volume without affecting performance. Companies with widely distributed networks are often better able to handle increasing requests.

Support and maintenance

The service provider should ensure support and be available to assist you at any time. It must have a dedicated team to address your questions, provide guidance and resolve any issues that may arise during the material retrieval process. For example, it should provide knowledgeable technical support. Ideally, provide 24/7 support.

Regular updates and bug fixes are also crucial to ensure a smooth experience. The best crawler services actively maintain their solutions, ensuring that they are always up to date and secure.

Please note that support is not limited to email or live chat, but also includes comprehensive documentation and FAQs. These resources make it easier for users to build powerful crawlers, providing necessary information and instructions. For teams of newbies, consider a service provider that offers training and onboarding assistance.

A Service Level Agreement (SLA) outlines the level of service you can expect from a provider. This includes guaranteed uptime, response time, and support issue resolution time. Before purchasing a plan, take some time to review the vendor's SLA. Confirm that it meets your expectations and business needs, especially if you have enterprise needs.

Comply with legal and ethical standards

Review the vendor's terms of service or user agreement document to ensure that its data extraction capabilities comply with legal and ethical guidelines. Complying with industry standards demonstrates a responsible and respectful approach to web crawlers.

In particular, data privacy is very important. Assess service providers’ commitment to complying with data protection regulations such as GDPR. Explore the measures it takes to securely handle data online and protect personally identifiable information (PII). Trust services that implement KYC (Know Your Customer) verification policies to maintain the integrity of their user base.

Consider your company’s approach to intellectual property. Check that the company respects copyrights and trademarks and opposes crawler activity that infringes on the rights of content owners.

Ethical considerations are also relevant. The best web scraping service providers do not retrieve sensitive or confidential information without authorization. Reputation and compliance records are also good indicators. Research the supplier's reputation and see if it has a history of litigation or ethical issues.

5 mistakes to avoid when choosing a crawler service

When choosing a crawler service that's right for you, you should avoid the following behaviors:

• Don’t be fooled by free services: prioritizing cost over quality can lead to poor results.

• Don’t ignore customer reviews: Ignoring user feedback may lead to working with an unreliable or unethical service.

• Don’t be afraid to ask questions: Contact sales support to get all the information you need before purchasing a plan.

• Don’t overlook performance evaluation: Not testing the performance of your service tools before signing up for a plan is a huge risk.

• Don’t stick with a service you don’t like: If the service provider doesn’t satisfy you, explore other solutions.
