Do website audits cost money or credits
Website audits do not use AI credits. They have their own separate limit called page audits.
Each page that gets scanned counts as one audit. If your site has 50 pages and you run a full audit, you use 50 page audits from your monthly allowance.
Page audit limits by plan
Starter: 500 pages per month
Pro: 2,000 pages per month
Scale 1: 3,000 pages per month
Scale 2: 6,000 pages per month
Scale 3: 9,000 pages per month
Scale 4: 20,000 pages per month
What counts as a page
Any URL that the crawler discovers and analyzes counts as one audit. This includes:
Your homepage
Blog posts
Product pages
Category pages
About us, contact, and legal pages
If your site has 200 pages, one full audit uses 200 page audits. You can audit the same site multiple times per month as long as you stay within your limit.
What are subdomains and should I audit them
A subdomain is a section of your website with its own prefix. For example:
blog.yoursite.com is a subdomain of yoursite.com
shop.yoursite.com is another subdomain
www.yoursite.com is also technically a subdomain
Should you audit subdomains
It depends. If your blog, shop, and main site are separate experiences with different content, you might want to audit them separately. If they are all part of the same site and share the same content strategy, audit them together.
In SnowSEO, you can:
Click the Subdomains button to see detected subdomains
Add custom subdomain hosts manually
Choose which subdomains to include in your audit
Exclude subdomains you do not want to track
By default, SnowSEO audits your primary domain. You need to explicitly add subdomains if you want them included.
How many times can I re-audit
You can run a new audit manually anytime by clicking Audit Now. Each new audit counts against your page audit limit.
Example
Your plan includes 500 audits per month. Your site has 100 pages.
First audit: 100 pages used, 400 remaining
Second audit: 100 pages used, 300 remaining
Third audit: 100 pages used, 200 remaining
You could audit the same site 5 times in one month before hitting your limit.
Automatic re-audits
You can also turn on Always-On Audit in Settings → Automation. This automatically recrawls your site on a schedule:
Every day
Twice every day
Every other day
Every 3 days
Every 7 days
Every 14 days
The available frequencies depend on your plan. Automatic audits count the same as manual audits against your monthly limit.
How is the audit score calculated
Your Site Health Score is a number from 0 to 100 based on three categories.
Technical (infrastructure)
Can Google crawl and index your pages?
Is HTTPS set up correctly?
Are there broken links, redirect chains, or crawl restrictions?
Are important pages accidentally blocked by robots.txt?
Are there server errors?
Content Quality (on-page SEO)
Do all pages have unique title tags?
Are meta descriptions present and well-written?
Are headings structured properly (H1, H2, H3)?
Do images have alt text?
Is there thin content (under ~300 words)?
Is there duplicate content?
GEO (AI visibility)
Does the content use structured data and schema markup?
Is the content formatted so AI crawlers can understand it?
Are there FAQ sections or HowTo markup?
Is the content clear and factual enough for AI platforms to cite?
Score ranges
90 to 100: Excellent. Your site is technically clean.
70 to 89: Good. A few things need attention.
50 to 69: Needs work. Some issues are hurting your performance.
Below 50: Critical. Serious problems need immediate fixes.
Each issue is weighted by impact. A broken link on 50 pages hurts your score more than a single missing alt text.
What about pages that were not crawled
Sometimes pages appear as Not Crawled or are missing from your audit report entirely.
Why pages might not be crawled
The page is not linked from any other page on your site (orphaned page)
The page is in your sitemap but the crawler could not access it
The page returned a server error during the crawl
The page is on a subdomain you did not select
The page is in your Excluded URLs list
What to do
Check the Sitemaps section to make sure your sitemap is detected
Verify the page is linked from at least one other page on your site
Make sure the page is not blocked by robots.txt
Add the page URL manually to your sitemap if needed
Remove the page from Excluded URLs if it was accidentally blocked
If a page is important for SEO but keeps showing as Not Crawled, check that it returns a 200 status code and is accessible without login or authentication.
