If the problem is in the backlinks department, you should dig through the ones you have.
Once you’ve found all the bad apples in your basket, take them down through any means available.
If you are able to remove them manually, do it. If you can talk to the person who manages the linking domain’s content, do it. For cases when these two options can’t work out, there’s the Google Disavow tool.
Then get the keywords on your site in order if you’ve messed up with them, too. Reduce their numbers until the text looks natural everywhere.
Can’t figure out what all this means and how to fix it? We have been doing this and watching for these algorithm changes for over 15 years now. We would be happy to look into any issues you’re having. Stay tuned for the “Pigeon” algorithm.
