The short answer
Most small and mid-sized businesses that invest seriously in SEO spend somewhere between $1,000 and $5,000 per month with an agency. Very low-cost plans often cover little more than reporting, while higher budgets usually mean more content, more locations, or a more competitive market.
At 4th Line, our Get Found plan starts at $1,500 per month and covers SEO, AI search optimization, Google Business Profile management, and monthly reporting.
What drives the price of SEO
- Competition. Ranking for "roofing company Detroit" takes more work than ranking in a small town or a narrow B2B niche.
- Number of locations. Each service area usually needs its own page and, often, its own Google Business Profile work.
- Content needs. New service, product, and location pages take research and writing time.
- Technical condition of your site. A slow or poorly built site may need fixes before content can rank.
- Authority building. Earning links and mentions from other trusted sites takes ongoing effort.
What a good SEO plan should include
- A technical audit and fixes for speed, indexing, and site structure
- A keyword plan tied to searches that signal buying intent, not just traffic
- New or improved service, product, and location pages
- Google Business Profile management for local businesses
- Authority building through links and mentions
- Monthly reporting on rankings, traffic, and the calls and forms they bring in
Red flags to watch for
- Guaranteed #1 rankings. No one controls Google.
- Reports that show only traffic or impressions with no tie to leads or sales.
- Long contracts with no clear deliverables each month.
- No access to your own Google Analytics or Search Console data.
How to tell if SEO is worth it
The simplest test is to compare what a new customer is worth to you against what you pay. If one new job, client, or order covers several months of SEO, the math usually works once rankings start bringing in steady leads. Expect early movement in 60 to 90 days and stronger results over 6 to 12 months.
SEO also lowers your dependence on paid ads over time and helps AI tools like ChatGPT and Google AI Overviews understand and recommend your business.
