What three paid plans cost a freelancer, as of November 2026
Semrush SEO plan, monthly billing $1,679/yr
Ahrefs Lite, monthly billing $1,548/yr
SE Ranking Core, monthly billing $1,548/yr
SEO Site Checker (unlimited) $0/yr
Range of the three yearly costs (monthly billing) $1,548-$1,679

As of November 2026. The range runs from the lowest to the highest of the three yearly costs above, all on monthly billing (our arithmetic: the monthly price times 12). On annual billing the three yearly costs run from about $1,238 to $1,408. Ahrefs also has a cheaper Starter plan at $29 a month ($348 a year, monthly billing only). Skipping a plan like these saves its yearly cost only if you do not need keyword research, rank tracking or backlink data.

Client Onboarding Workflow

The free SEO audit workflow for every new client

1

Audit the site before scoping

Run the client's URL through the Website SEO Score Checker before your first call. You'll immediately see the state of their on-page SEO including What's missing, what's broken, what needs priority attention. Walk into discovery calls with real data.

2

Check their domain profile

Use the Domain Authority Checker and WhoIs Lookup to understand the site's history and current authority. A low DA with a young domain needs a different strategy than a 10-year-old site with DA 40. The Blacklist Checker surfaces any email deliverability issues worth flagging to the client.

Domain Authority Checker →
3

Audit their key pages individually

Run the top 5-10 pages separately through the Meta Tag Analyzer. Note which pages have missing, duplicate, or truncated meta titles and descriptions. These are quick wins you can deliver in the first week and show immediate value to the client.

Meta Tag Analyzer →
4

Tackle image optimisation

Download the largest images from the client's site, run them through the Image Compressor, and upload the compressed versions. This is often the fastest and most visible performance improvement you can deliver and clients notice the speed difference.

Image Compressor →
5

Set up proper social sharing

Generate Open Graph and Twitter Card tags for the client's homepage and key landing pages. If they share any content on social media (or if visitors do), this ensures every link preview looks professional and includes the right image and copy.

Why Freelancers Choose This

No project limits. No per-seat fees. No subscription justification at month-end.

The problem with paid SEO tools for freelancers isn't that they're bad tools, it's that a plan you keep paying for suits steady retainers better than irregular project work. A freelancer running 5 client projects at $500-$1,500 each may struggle to justify $139.95/month (Semrush's SEO plan on monthly billing, as of November 2026) if the plan sits unused between gigs.

SEO Site Checker has no concept of project limits or per-seat pricing. Use it for 1 client or 20. Audit a site once or fifty times. The cost is always zero.

💼 What freelancers use most

  • Website SEO Score Checker: for every new client onboarding
  • Meta Tag Analyzer: across all client key pages
  • Domain Authority Checker: for client reporting and competitive research
  • Image Compressor: before uploading any client images
  • WhoIs Lookup: when researching client competitors
  • JSON Formatter / XML Tools: developer freelancers, constantly
  • Open Graph Generator: for client social media setup

FAQ

Questions from freelancers

Can I use SEO Site Checker on client websites? +
Yes, completely. SEO Site Checker audits any publicly accessible URL, you don't need to own the domain or have access to the CMS. Just enter the client's URL and run the audit. There are no project limits, no client limits, and no additional charges per site. A free account gives you PDF report downloads, which are useful for sharing results with clients.
Is there a limit on how many sites I can audit? +
No limits at all. You can audit as many client URLs as you need, as many times as you need. A free account allows up to 100 tool uses per day across all tools. If you're running large batches of audits, you can simply continue the next day or create multiple free accounts for different clients if needed. There are no project caps, seat restrictions, or per-client charges.
Can I download audit reports to send to clients? +
Yes. Creating a free account (no cost, no credit card) unlocks PDF report downloads for the SEO audit results. You can download the report and share it directly with clients as part of your deliverables or proposals. There's no paid plan required, just a free account.
Which tools do I need if I'm a web design freelancer? +
For web designers, the most-used tools are: Website SEO Score Checker (pre-launch and post-launch audits), Meta Tag Analyzer (checking every key page), Image Compressor (before uploading any images), Open Graph Generator (social sharing setup for the client's homepage and key pages), and Domain Authority Checker (for client reporting). If you do any code optimisation, the HTML/CSS/JS minifiers and XML Formatter are also useful.
How is this different from Semrush or Ahrefs for freelancers? +
Semrush and Ahrefs are subscription platforms that combine keyword research, backlink analysis, rank tracking and site audits, and many of their plans cap projects or websites and charge for extra users (as of November 2026, Semrush lists additional users from $45 a month, and Ahrefs Lite adds up to 2 more users at $40 a month each). SEO Site Checker is focused on the tools freelancers use most frequently: on-page audits, meta tag work, image optimization, domain checking, and developer utilities. It's also free with no project or seat limits, which makes it practical for freelancers who work across many different client sites without paying for extra seats.
Do I need an account to use SEO Site Checker? +
No. You can use any tool as a guest, just visit the site and start immediately, no sign-up required. Creating a free account (no cost, no credit card) unlocks full detailed reports, PDF downloads, and up to 100 tool uses per day. There is no paid account tier.
