Is there any connector or way to integrate with WebCeO.com?
This is the tool I pay for and includes rank tracking.
You can reach out to WebCeO and ask if they are interested in some type of partnership with SeoTools. You can also create a Connector yourself with our XML markup language. Our entire Connectors library is open sourced on Github so it is doable with some copy and pasting to get rolling.
