AI RankiaBuild topical authority with a topical map your site can win
Topical authority is covering a subject so fully that you become a go-to source on it. Content Hub drafts the topical map from your site, shows what you already cover, and orders the rest by how easy each topic is for you and how much it is searched.
Content Hub is included from the Brand plan ($349/mo).Data from
Keyword PlannerGoogle top 10
Search ConsolePublishes toWordPress
Informed by measured demand, when Google has it
Your topical map, from domain to a writing order
Content Hub starts from your site, language and country, not a typed topic. Volume is scanned free once the map is drafted; difficulty is a scan you run, or autopilot runs if you switch it on.
Pick the market
Domain, language and country. Then how to start:
New mapFrom your siteEcommerce · betaAI drafts the tree
Pillars, clusters and supporting topics from your pages, plus Google demand and AI fan-out gaps when there is data.
Measure the topics
Volume is scanned free after the draft, where Keyword Planner has data. KD is a scan you run (2 credits per topic) or let autopilot run; KD for you needs both authority numbers.
Write in that order
Autopilot writes from the top of the queue, on your schedule.
A map that knows what to write next
Pillar, cluster, supporting: built bottom-up
On a new site, a cluster waits until 40% of its supporting articles are live and a pillar until 60% of its tree, so both launch with links already pointing at them.
Growing sites, your pages, ecommerce
- Growing site: 25% and 45%. Established site: no gates, pillars weighted up
- From your site slots your existing pages into the tree and shows what is missing
- Ecommerce (beta) plans guides and comparisons around your catalog categories

KD, and KD for your site
We read Google's top 10 for each topic's main keyword and score it 0–100 with the weights Semrush publishes. KD for you adds your link-authority gap.
How it is calculated
- Inputs: links to ranking pages, domain strength, SERP features, volume, words in the keyword
- Not computed: follow/nofollow ratio (Semrush weight 9.17%), branded keyword (weight 3.50%)
- Plus a chance of top 10: how often published articles in the same KD-for-you band reached Google’s top 10, counted across Content Hub sites and then your own
KD for you = KD + 50 × (their authority − yours) / 100The map is the queue
One score orders the map, the month plan and autopilot. You set the pace, a monthly article cap, which titles to edit or reject, and WordPress publishing.
Map growth and pages you already have
- Expands the map when unwritten topics run low
- Skips topics an existing page already covers
A 0–100 score you can check
Win fast: the easiest first, even if few people search it. Balanced: recommended. Go for traffic: the most searched, even if they cost more.
Volume measured, not guessed
- After the map is drafted: one scan runs on its own
- Scan volumes: by hand, as often as you like
- On opening the map: only topics with no volume yet, at most every 30 days per browser
Fed by what AI engines searched
Cannibalization, before you write
- CSV and Google Sheets in and out
- Translate to a new language or country
- Expand by 50 topics at once
- Search Console clicks and position per article
What the map can’t tell you
!The tree is drafted by AI.
Review it. Its 1–3 label per row is shown but doesn’t move the score.
!Volume is Google Keyword Planner.
Rounded averages, often blank for long-tail; Google searches, not ChatGPT prompts. Under 20 ideas for your domain (common on new sites), the draft gets no demand data and volume is scanned afterwards.
!Difficulty drifts.
Google’s results change daily, so KD shows as bands, for each row’s main keyword only.
!KD for you needs two numbers.
Without your link authority and the competitors’, the cell stays blank.
!The chance of top 10 is an estimate.
It shows how many published articles in that difficulty band back it and says “little data yet” under 15: a rough guide, whatever the color.
!One map per market.
One per language and country. Replacing it is blocked once a topic is published.
