What an SEO agency does
An agency takes on the work: audit, technical fixes, content, links and reporting. Published guides put small and mid-sized business retainers at about $1,500 to $5,000 a month, with an average near $3,200. A one-off audit commonly costs $1,500 to $5,000, and a basic one $500 to $1,500. The price buys people’s time, so quality depends on who is assigned to your account.
The risk is vagueness. Some retainers send a monthly activity report and bill hours against loose tasks. Ask for named deliverables, who does the work and what you can see before the next payment.
What SEO software does
Software finds and reports. Research tools such as Semrush ($139 a month for its SEO plan) and Ahrefs (from $29 a month) show keywords, rankings and competitors. Tractionora starts from your own site and Google data and proposes a few changes for you to approve. In every case the doing is yours, unless the software can publish for you with your approval.
Software is cheaper and always on, and it needs someone with the time to read it. If nobody on your team has an hour a week for it, it will sit unused.
Free Forever costs nothing and includes Rapid Scan. Paid plans are listed at $39, $99 and $179 a month but cannot be bought yet.

|---|---|---|
| Typical monthly cost | $1,500 to $5,000 for small and mid-sized businesses | $0 to $449 for the standard plans we compared |
| Start-up cost | Often an audit first, $1,500 to $5,000 | Usually none, with a free plan or trial |
| Speed to first change | Weeks, after an audit and a plan | Same day, if you have time to read it |
| What you see | Reports, and quality varies by agency | Dashboards, as much as you read |
| Your time | A monthly call and approvals | Hours each week |
| Best when | You have no time and a budget for a retainer | Someone in-house can act on findings |
| Main risk | Vague activity billed by the hour | Data nobody acts on |
| Record of each change | Varies; ask for it in writing | Depends on the tool; Tractionora gives a Growth Receipt |
When an agency is the better choice
Pick an agency when nobody on your team has the time or skill to act on SEO findings, you have a monthly budget and you want the work done and explained. Look for named deliverables, a stated minimum term and a record of what each month changed.
When software is the better choice
Pick software when someone in-house can spend an hour or two a week, you want to see the evidence yourself and your budget is tight. A short list of approved changes you understand beats a long retainer you cannot check.
Can you use both?
Yes, and many businesses end up there. A common pattern is software for the evidence and the record, and a specialist team for the pieces you cannot or do not want to do, such as a rebuild or content. At Tractionora, a Growth Assessment from $1,800 is the usual first step for the team side, credited against a follow-on service started within 30 days.
