LSI keywords are words or phrases related to your keyword. They are not synonyms.
I like to think of them like this. If you have a page talking about a topic these are words you would probably be using. If you aren’t then your page probably isn’t that relevant to the topic and won’t rank that well.
One post I enjoy on LSI Keywords is: https://www.gobloggingtips.com/lsi-keywords/
My favorites ways of getting LSI keywords are:
- Google search
- Google analytics
- High ranking pages
There’s some tools to find LSI keywords and I need to use them more to see which ones I find useful. Have a good tool? Tell me about it!
