Open any SEO guide, find the chapter on faceted navigation, and it says the same thing. Filters make infinite combinations. Infinite combinations make thin pages. Block them, canonicalise them, keep them out of the index.
Eventbrite read that advice and did the opposite, on a scale that is difficult to believe until you count it.
We pulled its sitemap index and sorted the files by type. Most of them are exactly the pages you were told to hide.
Results at a glance
Of Eventbrite's 403 sitemap files, 335 hold filtered browse pages. Only 5 hold actual events.
The thing it sells is a rounding error in its own sitemap.
The pages you were told to hide
Every sitemap file is named for what it contains, which makes the shape of the strategy unusually easy to read.
Look at the URLs and the pattern is plain. /d/ca--granite-bay/monster-trucks/ is a city crossed with a topic. /d/ok--marlow/arts--events--this-month/ adds a time window. /d/il--midlothian/food-and-drink--parties--today/nye-free/ adds a price filter on top of that.
City, category, date range, price. Four dimensions, multiplied out, submitted for indexing on purpose.
A page called Today
The time filters are where this gets genuinely risky, so we opened one.
The URL is a "today" page. The filter panel confirms it. And every result underneath is dated tomorrow, because by the time we loaded it there was nothing left today.
That is the structural problem with indexing a time filter. The URL is permanent, the title promises a specific day, and the contents are whatever happens to be true at the moment a crawler arrives. Google gets a different page each visit, and so does a person arriving from search.
Eventbrite has decided that is an acceptable price. Given a domain rank of 98, it is hard to argue the trade has hurt it.
What the filters actually earned
So we measured the profile with our own Backlink Analyzer.
Domain rank 98 is the highest we have measured in this series, and the reason is not the filtered pages at all. It is that every organiser promoting an event links to their own listing, from their own site, their own newsletter and their own social posts.
Which reframes the whole strategy. The filtered pages are not earning the authority. They are spending it. Eventbrite has so much link equity from being the ticket link that it can afford to point Google at millions of thin combinations and still rank.
That is the part most sites copying this will get wrong. The facets work because the authority arrived first.
Two critical issues, both the same one
Our Website Audit gave the homepage 85 out of 100, with a perfect 25 of 25 on on-page SEO. Both of its critical issues were about hreflang: the page does not link to itself in its own language set, and its language links have no return links.
We wrote about exactly this failure when we looked at IKEA, which gets it right across 70 locales. Eventbrite, with a bigger domain rank, does not.
It is a useful reminder that a very strong site can carry a technical fault for years without visible punishment, and that "they rank, so it must be fine" is not a safe way to choose what to copy.
Copy this in an afternoon
The honest version of this lesson is mostly a warning, but there is a real technique inside it.
1. Separate the facets that are questions from the ones that are noise. "Free events in Chicago" is a thing people search. "Free events in Chicago, sorted by price, page 4" is not. Index the first, block the second.
2. Never index a filter that changes what the page means. Today, this weekend and this month are traps: the URL outlives the answer. City and category do not change.
3. Check whether you have the authority to spend. Eventbrite can afford millions of thin pages because organisers hand it links for free. Divide your referring domains by your page count before you multiply anything.
4. Give every faceted page a reason to exist. The ones that work here answer a question with a real, local, specific answer. The ones that do not are just a database query with a URL.
What you cannot copy
Being the link people have to share. Eventbrite's 2.45 million referring domains are a consequence of its product: you cannot promote an event without linking to where the tickets are. If nothing about your product forces other people to link to you, faceted pages will multiply your thin content without multiplying your authority, and you will get the downside of this strategy without the upside.
And here is what we could not check:
The page total is an estimate, and deliberately so. 403 sitemap files at up to 50,000 URLs each is roughly 20 million fetches against a live commercial site. We sampled the first, middle and last leaf of every type and multiplied, which puts the catalogue near 16.5 million URLs. The file counts by type are exact; the URL totals are not.
Declared pages are not indexed pages. This matters more here than in any other study in this series, because the whole question is what Google keeps. Only Eventbrite can see that.
We did not measure its AI visibility. Our checker has been unreliable behind its bot challenge this week, and we would rather publish nothing than a number from a run that did not finish.
No traffic or revenue data. None was available and none is claimed.
The Backlink Analyzer returns the referring domain count for any site in about a minute. Divide it by how many pages you publish. That number tells you whether you have authority to spend on filtered pages, or whether you would just be diluting what little you have.

Frequently asked questions
How big is Eventbrite's sitemap?
403 sitemap files, counted exactly on 25 August 2026. By type: 335 faceted pages, 36 directory category pages, 11 top search pages, 5 event pages, 5 category browse pages, 2 organiser profile pages, and one each of directory browse, things to do, points of interest, organiser, sell tickets, features, event ticketing, how to organise and marketing landing pages.
How many URLs is that?
Roughly 16.5 million, and that figure is an estimate rather than a count. We sampled the first, middle and last leaf of each type; most full leaves hold exactly 50,000 URLs. On that basis faceted pages come to about 13.7 million, directory categories 1.75 million, top searches 460,000, event pages 228,000 and category browse 202,000.
What is its backlink profile?
Our Backlink Analyzer returned Domain Rank 98 out of 100 — the highest in this series — with 2,451,399 referring domains, 921,394 referring IPs and 728,902 referring subnets.
Is indexing faceted navigation actually safe?
It is safe here because the authority arrived first and the facets map to real searches. It is not safe as a general technique. The failure mode is well documented: near-duplicate pages competing with each other, crawl budget spent on combinations nobody wants, and a catalogue where the actual product pages are outnumbered by filtered views of them. Eventbrite is living with all three and can afford to.
Why are time-based filters worse than the others?
Because the URL is permanent and the meaning is not. A page at .../parties--today/ promises a specific day in its title and its filter panel, but shows whatever is upcoming when it is loaded. We opened one and every event listed on it was dated tomorrow. City and category filters do not have this problem: a page about parties in Chicago still means the same thing next year.
What did the website audit find?
85 out of 100, with 2 critical issues, 0 warnings and 5 notices against 112 checks passed. On-page SEO was perfect at 25 of 25; technical SEO 62 of 67, speed 24 of 29, mobile 2 of 2. Both critical issues were hreflang faults: the page does not link out to itself, and its language links have no return links. The title tag is 58 characters, the meta description 58, and the page has one clear H1.
How does this compare with others in this series?
Referring domains per page: calculator.net 143 across 222 pages, Healthline 14.4 across 42,567, GeeksforGeeks 0.6, Eventbrite 0.148 across roughly 16.5 million, PyPI 0.082, Levels.fyi 0.026. Eventbrite has the most referring domains of any site we have measured and, because of the page count, a low ratio.
Should I unblock my own faceted pages after reading this?
Only the ones that answer a question somebody types, and only if you can name that question. The test is simple: would anybody search this combination in these words? "Wedding venues in Leeds" passes. "Wedding venues in Leeds, price ascending, 20 per page" does not. When in doubt the default advice still holds, because the downside of getting it wrong is much larger than the upside of getting it right.
Eventbrite is the most misleading case study in this series, because the obvious lesson is the wrong one. It is not "facets are fine now". It is that a site with 2.45 million referring domains has room to make choices that would sink a smaller one.

Measured on 25 August 2026. Sitemap file counts come from eventbrite.com's own sitemap index and are exact; URL totals are estimated by sampling the first, middle and last leaf of each type, because counting every leaf would mean roughly 20 million fetches. Declared URLs are not indexed pages.
Link and audit figures are free runs of our own tools, and the comparisons use the same tool earlier in this series. No traffic or revenue data was available to us and none is claimed here.
