One-time SEO vs a monthly retainer: which one does your business actually need?

The difference in one table

SEO (search engine optimisation) is the work that helps your business show up on Google and Google Maps. You can buy it in two ways: as a project with a start and an end, or as a monthly service with no fixed end.

What each option costs

The largest public survey of SEO prices is from Ahrefs, which asked 439 SEO providers what they charge. It is the main source for US figures below. UK figures come from a UK consultant's guide and from agencies' published prices.

Monthly retainers

• Overall range: Ahrefs found retainers usually run from $250 to $10,000 a month, with 63% of providers charging $500 to $5,000.
• Freelancer or agency: freelancers averaged about $1,348 a month and agencies about $3,209.
• Small and local businesses: about $1,557 a month on average, and 42% of providers charge small businesses $250 to $1,000.
• UK: Josh Willett, a UK consultant, gives £500 to £2,000 a month for freelancers, £2,000 to £8,000 for boutique agencies, and £500 to £1,500 for a narrow local campaign. Published prices checked by ExpertSure in October 2026 start lower: one provider lists local SEO from £185 a month plus a £195 setup fee, another lists retainers from £1,250, another from £1,967.

One-time projects

• Most common price: in the Ahrefs survey, the most popular project fee was $2,501 to $5,000, and about half of providers charge $2,000 or less.
• Freelancer or agency: freelancers averaged about $2,350 per project, agencies about $9,500. The most common freelancer fee was much lower, $101 to $250, which shows how many small one-off jobs are sold.
• Local SEO projects: about $5,700 on average.

Hourly rates, and where sources disagree

Ahrefs found an average of $111 an hour, with 90% of providers charging $150 or less. Josh Willett quotes £150 to £400 an hour for UK work depending on seniority, well above the Ahrefs average. Rates also vary hugely by country: Ahrefs found most providers in India charge $30 an hour or less. When you compare quotes, compare what is delivered, not the hourly rate.

When a one-time project is enough

A project is usually the better buy when most of these are true:

• You serve a local area. Google ranks local businesses on relevance, distance and prominence. Once your profile, pages and reviews are in order, you are not starting from scratch each month.
• The problems are specific. Missing service pages, an incomplete Google Business Profile, pages Google cannot find, a slow site on phones, inconsistent name and address across the web. These are jobs with an end.
• Competitors are not investing heavily. Search for your main service and town. If the businesses above you have thin websites and few reviews, a solid one-off fix can be enough to overtake them.
• You or your team can do light upkeep. Asking for reviews, answering them, updating hours and adding the odd page.
• Your budget is limited. One project priced at a few months of retainer fees can deliver the bulk of what a small business needs.

An audit is the usual first step, so the project has a clear list. See how much an SEO audit costs and what it should contain.

When a monthly retainer makes sense

• Your market is competitive. Personal injury law in a big city, cosmetic dentistry, national online stores. Competitors there keep adding pages and earning links, so standing still means slipping.
• Growth depends on new content. If you want to win dozens of service and location searches, someone has to research, write and publish pages every month.
• The site is large or changes often. Online stores with many products, firms with several offices, sites where new pages go up weekly.
• You have no time or staff. If nobody in the business will do upkeep, paying for it is better than letting it lapse.
• You can wait for results. Google's advice in a video for business owners was that in most cases SEOs need four months to a year to make improvements and then see benefit. A retainer cancelled after two months rarely shows what it could do.

A retainer only makes sense if the expected value covers the fee. Our guide is SEO worth it for a small business has a simple formula to check that before you sign.

What a good project and a good retainer month contain

Whichever you choose, you should be able to see what you paid for. Use these lists to compare proposals.

A well-scoped one-time project

• A starting measurement. Your position on Google and Google Maps for five to ten named searches, written down before any work begins.
• A numbered list of fixes. For example: rewrite the home page, add a page for each main service, complete the Google Business Profile, fix pages Google cannot find, add a call button on phones.
• Who does what. Which fixes the provider makes on your site, and which they hand to you or your web designer.
• A fixed price and an end date. Agreed before the work starts, with anything extra quoted separately.
• A handover. A short report of every change made, and the upkeep list you should follow afterwards.
• A follow-up check. The same searches checked again after a few months, so you can see what moved.

A good retainer month

• Named tasks. "Two new service pages for Leeds and Harrogate, five broken links fixed, review requests sent to last month's clients", not "ongoing optimisation".
• A short report in plain words. What was done, what changed in positions, calls and enquiries, and what comes next month.
• Numbers tied to the business. Calls, form sends and bookings from search, not only traffic or rankings for your own name.
• A plan that changes. If something is not working after a few months, the provider should say so and change course.

If a monthly report looks the same three months running, ask what the fee is now paying for.

What happens after a one-time project ends

Rankings do not disappear the day a project ends. Google's own starter guide treats SEO as something to maintain over time, though, and three things wear a one-off fix down: competitors improving, your business changing (new services, new staff, a move), and your website ageing. Here is the upkeep a small business can do itself:

The middle path most small businesses end up on

For many small firms the best value is neither pure option. It looks like this: an audit to find what matters, a one-off project to fix it, then light monthly care or your own upkeep, with the same searches checked again every few months. If the numbers stall while competitors pull ahead, that is the moment to consider a fuller retainer, based on evidence rather than a sales pitch.

This is how we price our own work. Our Fix package starts at a fixed $1,500, below the freelancer average of about $2,350 per project in the Ahrefs survey. Our Monthly care starts at $150, below most retainers, because it covers upkeep and monthly re-checks rather than a full campaign. Prices are on our pricing section.

Questions to ask before you sign either

1. What exactly will you deliver? For a project: the list of fixes. For a retainer: what gets done each month (pages written, fixes made, reviews requested), not just "ongoing optimisation".
2. How long is the contract, and what is the notice period? Month-to-month or a short minimum is easier to live with than a 12-month lock-in.
3. What results do you expect, by when, and how will we measure them? Google suggests asking exactly this. Agree the searches and numbers at the start.
4. Will you show me every change you make? Google also recommends asking for full details of changes and the reasons behind them.
5. Who owns the work? Pages, content, your Google profile and your analytics should stay yours if you leave.
6. What happens when I stop? Nothing you paid for should be switched off or taken down.

Red flags in either model

• A guarantee of first place. Google says no one can guarantee a number one ranking.
• Reports that only show rankings for your business name, or traffic with no calls or enquiries.
• Monthly fees with no named tasks, month after month.
• Buying links. Google's spam policies count exchanging money for links as link spam, which can harm your rankings.
• A provider who holds your Google Business Profile or website in their own account.
