An AI SEO agency helps businesses improve their visibility in AI-generated answers. Traditional SEO focuses on organic search visibility and website performance. Our AI SEO work adds prompt tracking, citation research, content improvements and outreach to relevant sources. We use these alongside technical SEO, useful content and authority building.
We research the questions buyers ask, examine cited sources and improve content and coverage to support your visibility. For Workyard, AI citation building and AI content optimization led to appearances in answers about “construction management software” on ChatGPT and Claude within three months. AI platforms choose their own answers, so a particular recommendation or position cannot be guaranteed.
Our published Workyard case study reports a 1,839% increase in organic clicks over 21 months through link building and digital PR. A separate AI search campaign achieved visibility on ChatGPT and Claude within three months. Across our client campaigns, we have generated a lifetime total of $1.2 billion in revenue attributable to our SEO work. Explore the Workyard results.
We agree on campaign goals before work begins. SEO reporting can cover search visibility, organic traffic and the leads, sales or sign-ups tracked on your website. Our AI visibility tracker measures how often your brand appears for monitored prompts and shows mentions, reported position, cited sources and changes over time. You can compare brands and filter results by model and date. These AI metrics describe the monitored answers; they are separate from website conversions.
Our SEO engagements start at $1,500 per month. The scope depends on your website, competition and goals. Selected AI SEO activities can be included within the agreed budget, with the allocation and deliverables outlined in your proposal. Broader campaigns are priced according to the work required.
Timing depends on your starting visibility, competition, website condition and the work involved. Workyard’s published SEO case recorded substantial traffic growth in the fourth month, with the reported 1,839% organic-click increase measured over 21 months. Its separate AI campaign achieved visibility within three months. These are campaign examples; we assess your situation before discussing an expected timeline.
