URL class inventory and indexation model
Every class XenForo generates — threads, paginated thread pages, forums and sub-forums, member profiles, tags, prefixes, search URLs, what's-new and activity routes — enumerated and decided on. The decision table is the deliverable, because consistency across classes is what prevents the duplication the model exists to control.
Thread and pagination indexation
Making a long thread's later pages crawlable and linked coherently, so answers that emerged on page four can be found. This is where forums most commonly lose their own best content, and the fix is in linking and canonical handling rather than in markup.
Deep archive internal linking
The paths a crawler and a reader take through a decade of threads: related threads, tags, prefixes, forum hierarchies, and the cross-references members already make in replies. Forums have weak generated linking and strong human linking, and surfacing the second is where the archive becomes findable.
Thin and duplicate handling
Short threads, empty forums, single-post tags, duplicate discussion and the near-duplicates produced by merging and splitting. Classified by class, with a decision for each rather than a blanket rule that would discard real content along with the noise.
Template-level audit
Canonicals, structured data, headings, meta and the served HTML across each XenForo template. A theme is where forum search problems most often originate, and a single template defect affects every thread or every profile at once.
Crawl health and rate
How much is being crawled, of what, and how quickly new threads are discovered — including the cases where a slow or unstable response has reduced crawl rate. On a large community this is frequently the real constraint behind a discovery complaint.
Sitemaps for a forum estate
Sitemaps generated for threads and other intended classes at the volumes a large forum reaches, split and prioritised so the crawl reaches content rather than listings.
Q&A visibility
Making the question-and-answer content inside threads legible as such — the discussion structure, the accepted answer where one exists, and the page's own title and headings reflecting the question people actually search for.
Measurement per class
Impressions, clicks and coverage split by threads, forums, profiles, tags and pagination, before and after. On a forum an aggregate figure is close to meaningless, because the change that matters is a shift between classes rather than a total.
