The Short Answer
SEO runs anywhere from $300 to $10,000+ per month depending on who you hire and what they're actually doing. For a small or mid-size service business, the realistic range is $500 to $5,000 per month. Below $500, you're mostly paying for reports that don't move anything. Above $5,000, you're getting into competitive national campaigns or large-scale programmatic builds.
The number that matters isn't the monthly fee. It's what you get for it. A $1,500/month retainer from an agency that writes two blog posts and sends a PDF is a worse deal than a $3,000/month engagement that builds 500 indexed pages targeting every city you serve. One of those creates compounding organic traffic. The other keeps someone employed.
Before you shop for an SEO price, get clear on what you actually need: local visibility in one market, multi-city coverage, or a high-volume content engine. The right answer changes the budget significantly.
What Each Price Tier Actually Gets You
Here's how most SEO engagements break down by monthly spend, what you can realistically expect, and what the limitations are at each level.
| Monthly Budget | What You Typically Get | Best For | What's Usually Missing |
|---|---|---|---|
| $300 – $750 | Basic on-page audit, 1-2 blog posts, GMB updates | Brand-new sites, low-competition local niches | Link building, technical work, real content volume |
| $750 – $1,500 | Monthly reporting, keyword tracking, 3-5 blog posts, some citation building | Single-location service businesses | Enough content to compete in mid-size markets |
| $1,500 – $3,000 | Full technical SEO, consistent content, link outreach, local landing pages | Multi-location or growing businesses | Programmatic scale, complex site architecture |
| $3,000 – $5,000 | Strategy, content at volume, link building, city/service page builds | B2B companies, multi-market contractors | Custom programmatic infrastructure |
| $5,000+ | Programmatic SEO, large-scale page production, dedicated strategy | High-competition industries, regional/national reach | Nothing, if you choose the right shop |
$300 to $750 Per Month
At this price, most of what you're buying is someone's time on basic tasks. You'll get a Google Business Profile cleanup, maybe a handful of citation submissions, and a blog post or two per month. If you're a brand-new business with no online presence and you're in a small market, this might be enough to get indexed and show up for a few terms. But if you have any real competition, $500/month SEO is like putting a garden hose on a house fire. It's not nothing, but it won't get you where you need to go.
$750 to $1,500 Per Month
This is the most common range for small business SEO retainers. You'll get regular reporting, some keyword tracking, a few pieces of content per month, and light link building. For a single-location plumber or HVAC company in a smaller metro, this can work if the agency is focused. The risk here is that a lot of agencies in this range charge for activity instead of results. They'll send you a report showing 12 new citations and three blog posts, and your rankings won't move because nobody actually addressed your technical issues or built any authority.
$1,500 to $3,000 Per Month
This is where real work starts to happen consistently. A good agency in this range should be doing technical audits and fixes, producing enough content to actually build topical authority, and actively building links or citations. For a contractor covering a few cities or a law firm targeting practice-area keywords, this budget can move the needle in 6 to 12 months. You should expect transparent reporting on rankings, impressions, and traffic, not just deliverable counts.
$3,000 to $5,000 Per Month
At this level, you can expect dedicated strategy, higher content volume, and some form of geographic expansion work. This is where city-plus-service landing pages start coming into play. A roofing company covering a metro area with 20+ suburbs needs a page for every city-service combination to capture that search volume. Building and optimizing those pages at any real speed requires a budget in this range.
$5,000 and Up Per Month
Above $5,000, you're typically funding either a national-scale campaign, a programmatic SEO infrastructure build, or both. Programmatic SEO means generating thousands of indexed pages targeting specific search combinations at scale, city plus service, product plus location, question plus industry. This is how a junk removal contractor we work with crossed $72,000 in a single month from Google traffic alone with zero ad spend. Their site now has over 70,000 indexed pages. That kind of result doesn't come from writing blog posts. It comes from a purpose-built content architecture designed to capture search volume at scale.
Mistakes to Avoid
Buying the cheapest option and expecting full-service results
A $400/month SEO retainer is not a discount version of a $2,000/month retainer. It's a fundamentally different scope. If someone is charging $400/month, they are physically incapable of doing what a $2,000/month engagement can do in terms of hours and output. Expecting big-agency results at starter-package prices is how business owners end up frustrated and convinced that SEO doesn't work.
Paying for activity instead of outcomes
Monthly reports full of "deliverables" like blog posts published, citations added, and keywords tracked are not the same as results. Ask any SEO agency you're considering to show you examples of ranking improvements and traffic growth they've driven for clients in your industry. If they can't show you that clearly, they're selling you activity, not outcomes.
Signing long contracts before seeing any proof of work
Some SEO agencies require 12-month commitments before they've shown you anything. Six months is reasonable because SEO takes time. Twelve months upfront with no performance benchmarks written in is a risk. Get clarity on what the agency commits to deliver and at what point in the engagement, before you sign.
Confusing cheap offshore content with real SEO
You can find vendors who will publish 30 articles a month for $300. The problem is that thin, generic, AI-spun content doesn't rank in competitive markets and can actually hurt your site's standing. Google's quality assessments have gotten sharper. If your SEO budget is mostly paying for bulk content with no strategy behind it, you're building on sand.
Ignoring the technical foundation
A lot of business owners chase content and links while their site has crawl issues, slow load times, duplicate pages, or broken internal linking. Technical SEO isn't glamorous but it's foundational. If the site can't be crawled and indexed correctly, no amount of content or link building fixes that. Make sure whoever you hire audits and addresses technical issues, not just writes blog posts.
How CodeWCG Approaches This
Our builds typically start at $5,000 for the initial development work, and ongoing retainers are scoped based on what actually needs to happen for your specific market and competition level. We're a Houston-based shop that has worked with 60+ B2B clients since 2019, mostly service contractors, and we're direct about what we think you need and what we think is overkill for your situation.
What we focus on is programmatic SEO infrastructure. That means building sites or sections of sites designed to index thousands of pages targeting specific city-service-keyword combinations. Our own production site runs over 193,000 indexed pages across programmatic combinations. That's not a vanity metric. It's proof that the architecture works. The junk removal contractor mentioned earlier didn't get to $72,000/month in organic revenue because someone wrote great blog posts. They got there because their site had the infrastructure to capture search demand at volume across every relevant geography and service type.
We won't take on a client if we don't think we can make a real difference. We're not the right fit if you want someone to manage a small blog and track your GMB. There are cheaper options for that. Where we make sense is when you're trying to scale organic traffic across multiple cities or services and you want a build that compounds over time instead of a retainer that resets every month with nothing to show for it.
Final Answer
SEO costs anywhere from $500 to $5,000 per month for most small and mid-size businesses, and the price is only meaningful in context of the scope. Low-budget retainers can work for brand-new businesses in uncontested markets. Mid-tier budgets work for single-location or early-growth companies who need consistent content and technical attention. Higher budgets are where multi-location operators and competitive industries start to see real scale, especially when programmatic infrastructure is part of the build. The key question isn't what the going rate is. It's what kind of SEO your specific situation actually calls for, and whether the agency you're looking at has done that kind of work before.
