Online keyword ranking query written in PHP. For Baidu , you can query multiple domain names and multiple keywords in batches. Copy it to your space and run it. Because this tool needs to capture Baidu data, the number of keywords should not be too large. A few hundred at a time is enough. All keywords and domain names to be queried need to be added manually in an xml file (there are examples). If the query volume is too large, multiple xml files can be prepared. Recommended usage environment: PHP environment installed on your local computer.
