Back in early May I started registering domains for Roblox game fan sites. The goal was to test whether EMD (exact-match domain) sites with specific, first-person content could rank without a heavy backlink push. Six sites, 40 days, here is the actual data.
Why Roblox specifically
Google's March 2026 core update penalized thin game guide content pretty hard but left dedicated fan sites mostly untouched. The pattern I noticed: sites with tool pages (calculators, code trackers, value lookups) held positions while pure wiki-style sites dropped. Roblox has a steady stream of games with high search volume and underserved SERP real estate.
The six sites
All six follow the same structure: an EMD domain registered within 24 hours of deciding a game was worth targeting, a tool page as the flagship piece, and spoke content covering the specific questions that show up in autocomplete.
Roblox creature battle (Kaiju Alpha tier)
XP grind optimization is underserved in most creature battle games on Roblox. The level 35 inflection point -- where build diversity starts mattering and generic advice stops working -- was generating autocomplete suggestions with no dedicated page answering it. I targeted that specific question.
Hospital roleplay simulation (Maple Hospital tier)
Consistently top-visited games on Roblox often have the worst documentation. Hospital sims are a good example: complex job role systems and karma mechanics that the game never explains. The search volume exists but almost no dedicated sites cover it.
Tower defense with unit comparison gaps (UTDX tier)
Tower defense games live on unit comparison data. DPS calculators, cost-efficiency ratios, upgrade breakpoints. I reverse-engineered the damage formula on one game and the DPS calculator page became the highest-traffic page on the site within two weeks.
RNG gacha with pull probability questions (Slime RNG tier)
Gacha mechanics generate constant search traffic around probabilities. "What are the odds of getting X?" queries are high-volume and specific. The luck calculator page alone drives most sessions on the site.
Codes tracker (Sell Lemons tier)
Active code lists with expiry tracking are evergreen Roblox content. The key differentiator is accuracy -- codes that expire get flagged immediately rather than staying on the list for weeks. This site launched most recently (mid-June) so it has the fewest data points so far.
Trading value calculator (Trade Squishy Dumplings tier)
Trading games need value calculators more than any other Roblox genre. The mutation multiplier problem (where the same item is worth 3.5x with a mutation) makes manual math slow. A calculator page that handles multipliers automatically tends to see high dwell time.
What the data shows
Across all six sites:
- Indexed: 7 to 14 days post-launch (IndexNow accelerated this significantly)
- First impressions: appeared in GSC before any external backlink was live
- Tool pages: 2 to 3 minutes average dwell time
- Pure text pages: 35 to 50 seconds average dwell time
The dwell time gap was larger than I expected. Users on calculator and code tracker pages behave differently from users on guide pages -- they interact with the tool, check a result, and often return on the same session. GSC queries on tool pages skew more transactional.
What did not work
Generic beginner guides with broad scope got the least traction. Pages that answer one specific question clearly outperformed pages that tried to cover everything.
The "complete guide" format I tested on two sites got crawled and indexed but showed poor engagement signals in the first 30 days. I have since rebuilt those pages around specific questions instead.
What's next
The 40-day window closes for most of these sites in the next two weeks. Mid-tail keywords should start moving in the top 10 range. I will post a follow-up with 6-week numbers.
If you're curious about any specific site or the EMD selection process I used, ask in the comments.
