There could be several reasons why your publications are not appearing on your ResearchGate profile page. Here are a few possibilities:
You may not have added your publications to your ResearchGate profile yet. You can add them by clicking on the "Add new publication" button on your profile page and filling in the required information.
Your publications may already exist on ResearchGate, but they are not linked to your account. You can search for your publications on ResearchGate and claim them by clicking on the "claim" button.
If your publications are not already on ResearchGate, it may take some time for them to appear on your profile page after you add them. This is because ResearchGate needs to verify the information and make sure it meets their guidelines.
If you have added your publications to your profile but they are still not appearing, there may be an issue with the indexing of your profile in ResearchGate's search algorithm. In this case, you may need to contact ResearchGate support for assistance troubleshooting the issue.
I hope this helps! If you have any further questions or concerns, please let me know.
