If you are not sure, about topics to write on then this tool could help you. [URLnf="https://answerthepublic.com/"]Answer the Public[/URLnf], all you need to do is put your target keyword then it will generate all available topics one should write about. If you are not to mention could offer you more phrases then search results suggestions. I'm not saying that suggestions from search results is bad idea, but that tool could save you sometime as it does the same thing as search results does.
One should know about boolean string too. It comes handy for searching required stuff, I hope you got what I meant.
