I found this method to be effective for building your internal linking strategy
If you are building a Blog Start with “building Relevant tags”
Type these tags on an excel sheet or notepad. List all yoru tags here. You should never use any extra tags outside of this list on any of your blogs.
Create a list of Tags that revolve around your business on a sheet on notepad.
For all the blogs that you create, add tags relevant to the article from these tags that you have created only. Dont add random tags.
Once you start building your internal linking strategy,
Search for all the content that is grouped via these tags.
Now start internal linking each of these pages
