I've been exactly where you are-solo marketer, juggling everything from blog drafts to schema audits. honestly, no single tool handles SEO, content planning, and AEO well yet, because AEO is still a totally different signal layer from traditional search.
for SEO and content, i still stick with Ahrefs for keyword research and topic clustering, then a simple Notion calendar to track drafts and publish dates. That bit's straightforward.
AEO is a different beast-you're not optimising for rankings, you're optimising for whether an AI model picks your content as a source. the tools that track brand mentions in AI answers are handy for awareness, but they won't tell you why you're not being cited. What worked for me was manually auditing my top 20 pages against queries that actually trigger AI citations-comparison tables, structured lists, FAQ blocks with schema. The pages with extractable content (tables, pros/cons, clear verdicts) showed up. the narrative blog posts? not so much.
My workflow now: keep your SEO tool for keyword discovery, use a simple CMS or spreadsheet for planning, and for AEO, focus on restructuring your existing high-traffic pages into formats AI can pull directly. that's the part most solo marketers skip because it feels like rework, but that's where the visibility gain actually lives 😊
