What AI SEO tools can and can’t do

AI speeds up research, briefs and drafts. It doesn’t replace original expertise, real data or links, and thin AI content tends to underperform. Use AI for the grunt work and humans for judgment.

Tracking AI search visibility

As more searches end in AI answers, tools now report how often your brand is mentioned or cited in ChatGPT, Google AI Overviews and Perplexity. Semrush includes this from its Starter plan.
