Advices to streamline the costs of my SEO kit? Semrush vs Haloscan?

Hello everyone, I am looking to streamline the costs of my SEO kit. I am working on my company's website, which has around 350 pages. I would like your feedback, suggestions, or critiques: 1) I use Semrush Pro ($140/month) to find keywords, track rank progress, and handle technical aspects. I plan to replace it with Haloscan Free (€0) or Starter (€59) for keyword research and rely more on Screaming Frog for technical tasks. Potential savings: $140 if I can stick to the free versions. 2) I currently use Inlinks ($58) for internal linking and to add entity markup to my articles (I’m working on building my site’s topical authority using a wiki graph + Inlinks). I’m considering replacing Inlinks with Linkboss for internal linking because: a) there’s no link deletion upon subscription cancellation, and b) the cost is lower (the $8 subscription might suffice?). However, I’m unsure about schema markup. The schema tool in Rankmath Pro (which I use) seems inadequate, and I’m not sure what to do here. 3) I use [Yourtext.guru](http://Yourtext.guru) Lite (€99) for writing, creating semantic clusters, and conducting basic keyword/entity research. I don’t know how to replace this. I’ve taken the training course by its creators, who are algorithm researchers. To my knowledge, this tool has no equally effective alternative. Its design goes far beyond simply averaging keyword presence in the top 10 for filling content... 4) Lastly, I use Rankmath Pro ($6.99), which I paid for annually and will expire in April. For now, I’ll continue using it to complement position tracking with Haloscan. By replacing Semrush with Haloscan and Inlinks with Linkboss, I could save €200 per month. For my other major expense, [Yourtext.guru](http://Yourtext.guru), I’m stuck... any ideas? Any advice, feedback?
