Seo Tool recommendation?

Hi, I need an SEO tool for keyword analysis, backlink checking, and competitor analysis. Currently, I’m using a two-week SEMrush membership from forums, but it’s not ideal to restart everything repeatedly. Do you have any recommendations? I tried SiteGuru but didn’t like it, and I’m unsure about Ubersuggest either.

We have blog too so keyword analysis is really important for me.
