Here is my personal sentiment
At present, there are many popular collection tools in the webmaster circle, but in summary, there are just a few well-known free tools.
1. The number of people using the locomotive should be the largest, mainly in the new station
Features: many features and high speed
Advantage: The function is complete and the collection speed is fast. It is mainly for CMS. It can collect a lot in a short time, filter and replace all are good, and it is more detailed. Many people write interfaces and publish them, the interface is relatively complete, suitable for webmasters who do not know the program
Technology: The technology is mainly supported by forums. There are many help files and it is easy to get started. Free Version
Disadvantages: more and more functions, more and more expensive memory, faster speed, lower collection quality, unstable
2. The trio is mainly used for forums and can be referred to as the first person in the Forum.
Features: Migration and mobile targeting major forums, fast speed, and high accuracy
Advantage: it is suitable for forums.
Technology: Paid technology, free ads
Disadvantages: Poor CMS support
3. Et Tool
Features: unattended, stable, and barely occupied memory
Advantages: unattended, automatic updates, suitable for long-term station building, the user base is mainly concentrated in the long-term station diving webmaster. The software is clear and the necessary functions are complete. The key is that the software is free of charge. I heard that the collection and translation functions have been added.
Technology: Forum support, the software itself is free, but it also provides paid services. There are few help files and it is not easy to get started
Disadvantage: It seems that the software has fewer help files.
4. Haina
Features: massive, keyword capturing, preview of collected content without writing rules
Advantage: a large number of keywords can be crawled on the website. It seems suitable for website topics.
Technology: no forum charges, free of charge with functional limitations
Disadvantages: The classification is inconvenient. That is to say, it is inconvenient to classify collected articles. Manual (automatic obfuscation is easy) is required, and specific interfaces are required.
Conclusion: If you are pursuing a complete set of functions, you should choose the locomotive. the locomotive is called "omnipotent". In the early stage, you can quickly collect a lot of resources and enrich the website content. If you want to create a forum, you can select the Third Party. If you are right, you can collect forums, reply, move, and other Forum functions. If you choose et for a long term, it will be a long-term benefit if you take some time to understand it. Write the rules, set the filtering and replacement, and then run for a long time like QQ, without memory fees, automatic collection and update, clear classification, and complete collection content. However, one site, A Webmaster + ET is enough. As for Haina, it seems that it is easy to get started without writing rules. However, in the release of articles, it cannot be like ET once and for all. Instead, it feels that it has increased a lot of work, but it can be used as a topic, this is a good choice for website topics.
