The 5-Minute Domain Valuation: Using Majestic TF/CF and Moz DA for Beginners
发布者:Peter Nagy · AI 辅助 · 2026年11月10日 · 阅读需 5 分钟
You don't need a degree in SEO to value a domain. In five minutes, with two free tools and three numbers, you can tell if a domain is worth buying or belongs in the graveyard. This process works for indie hackers, domain investors, and anyone who just found a parked domain and wonders, 'Is this thing worth anything?'
Step 1: What tools do you need to start?
Two free tools: Majestic.com for Trust Flow (TF) and Citation Flow (CF), and Moz.com for Domain Authority (DA). Both offer limited free tiers that give you enough data for one-off checks. You don't need paid plans unless you're checking 50+ domains a day.
Bookmark the bulk-checker pages if you're serious. Majestic's free account gives you 10 lookups per day. Moz's free account gives you 5 DA lookups per day. That's plenty for a beginner.
Step 2: What are TF, CF, and DA in plain English?
Trust Flow measures how many 'trustworthy' sites link to a domain. Citation Flow measures raw link count. Domain Authority predicts how likely a domain is to rank in Google. Think of TF as quality, CF as quantity, and DA as Google's mood about the whole thing.
A healthy ratio is TF close to CF. If CF is 40 and TF is 5, that domain has lots of spammy links. If TF is 40 and CF is 30, that's a clean profile. DA is a 1-100 score; anything above 30 is decent for a side project.
Step 3: How do you check TF and CF in 30 seconds?
Go to Majestic.com, paste the domain into the search bar, and hit enter. The free report shows TF and CF right at the top. Write both numbers down. The site also shows a 'Trust Flow / Citation Flow' ratio chart - look for the green zone.
If the domain has zero TF and CF, that's not always bad. It could be a brand new domain or one that never had links. You'd just be buying the name itself, not any SEO value.
Step 4: How do you check Moz DA in 30 seconds?
Open Moz's Link Explorer (free tier), paste the domain, and hit search. The DA score appears instantly. Moz also shows 'Linking Domains' - that's the number of unique sites linking to the domain. More linking domains usually means a stronger profile.
Moz's free tier only shows the top 5 metrics, but DA is the one you need. Write it down next to your TF and CF.
Step 5: What's the 5-minute valuation formula?
Add TF and DA together. That's your rough 'quality score'. Subtract CF from TF. If the difference is negative by more than 10, deduct points. If TF is higher than CF, add points. A domain with TF 20, DA 30 (score 50) and CF 15 (TF > CF) is a solid buy for a side project.
Don't overthink it. The formula is: TF + DA - (CF - TF if CF > TF). If CF is 40 and TF is 5, that's 5 + 30 - (40 - 5) = 0. That domain is trash. If TF is 30 and CF is 20, that's 30 + 30 - 0 = 60. That's a good domain.
Step 6: What can go wrong with these metrics?
Everything. Metrics are lagging indicators. A domain with high TF and DA might have been penalized by Google last week. Moz and Majestic don't update daily. Also, some domains have fake links that look good to Majestic but not to Google.
Always cross-check with a manual glance at the domain's backlinks (free Majestic shows the top 5). If every link is from 'free-backlinks-for-you.com', run. If links are from real blogs or news sites, you're golden.
Step 7: When should you just skip the valuation?
When the domain has zero metrics across all three tools. Zero TF, zero CF, zero DA. That domain is a brand-new registration or a dead name. You're buying it purely for the name itself - not for any SEO head start.
Also skip if the domain is an exact match for a trademarked term. You don't want a cease-and-desist letter. Quick check: Google the domain name alone. If the first result is a legal firm, walk away.
Step 8: How do you apply this when browsing dead projects?
Head to browse the graveyard and look at domains from dead side projects. For example, standupify.com (died of no users) - you'd check its TF, CF, and DA to see if the domain itself has any link value left from its failed run.
Some dead projects had real users and real backlinks. Even if the product died, the domain might be worth picking up. Demo Grave (died of no users) is another example - a dead project's domain can still carry SEO weight.
Step 9: What's the fastest way to practice?
Grab three random domains you already own or find three from the graveyard. Run each through Majestic and Moz. Write down TF, CF, DA. Apply the formula. Do it for five minutes a day for a week. You'll develop an instinct for what a 'good' score looks like.
Google (died of other) is a joke example - but it shows that even a dead domain can have a backlink profile worth examining. Just don't expect to buy it.
Step 10: How do you turn a valuation into a purchase?
Once you've valued a domain and want to buy it, check if it's listed on a marketplace like Afternic or GoDaddy Auctions. If it's not listed, you can try contacting the owner through WHOIS (use a privacy service). Many owners on dead.domains list their email for direct contact.
Never pay more than your formula suggests. If the domain scores 50 and the seller wants $500, that's probably too much. If it scores 50 and they want $50, that's a steal. Trust the numbers, not the story.

常见问题
Can I value a domain without any tools?
You can guess, but you'll be wrong. Free tools like Majestic and Moz are the bare minimum. Without them, you're just picking a domain because you like the name - which is fine for a personal project, but not for an investment.
What if TF and CF are both zero?
That means the domain has no backlinks at all. It's a fresh registration or a name that never got used. You're buying the domain itself, not any SEO value. That's okay for a new project, but don't pay extra for it.
How often should I re-check a domain's metrics?
Check once before you buy, then again after 3-6 months if you still own it. Metrics update slowly. Checking daily is a waste of time unless you're tracking a specific domain you're trying to sell.
Is DA more important than TF?
No. They measure different things. DA is Google's prediction of ranking ability; TF is link quality. A high DA with low TF means the domain might rank but has spammy links. A high TF with low DA means quality links but low overall authority.
Can I use these metrics for expired domains?
Yes. Expired domains often have existing backlinks. But check the 'Wayback Machine' first. If the domain was a spam site before expiry, those links could be toxic. Metrics alone won't tell you the full story.
