What is a monthly SEO retainer?

A monthly SEO retainer is ongoing management of your organic search visibility, run by an agency or a consultant: an initial audit, a strategy, execution of the actions every month (technical, content, internal linking, link building, GEO) and reporting on the results. The goal is not to "be on Google", it is to turn SEO into a channel that generates enquiries and sales, month after month.

The difference with a one-off service fits in one sentence: the SEO audit says what to do, the retainer does it. Google updates its criteria constantly, your competitors keep publishing, AI is changing the way people search. A site optimized once loses ground; a site managed every month gains it.

The 3 pillars of our monthly SEO retainer

Search visibility that keeps growing rests on three pillars worked on together. Neglect one of them and you hit a ceiling.

Technical SEO: the foundation

Indexing, speed, Core Web Vitals, URL structure, structured data, site security. If Google crawls your site poorly, the best content in the world stays invisible. We monitor and fix continuously.

On-page SEO: content that ranks

Keywords aligned with your sales, service pages, articles, local pages, optimized copywriting and internal linking. Every page answers a search intent that pays, not a keyword picked at random. For an online store, that also means category and product pages: see our e-commerce SEO agency.

Off-page SEO: the authority that decides

Progressive editorial link building, citations and brand mentions. With equal content, domain authority decides who makes it to page one.

What happens, month by month

The retainer comes with no long-term contract, but let's be clear: SEO requires consistency. Ideally, plan on at least 3 months to see the first solid results. Here is what a typical retainer looks like.

1
Month 1

Audit, roadmap and quick wins

We start with a full audit of your site and your market. This gives us a prioritized roadmap, and we immediately fix what is already holding back your visibility: technical errors, tags, poorly optimized pages.

2
Month 2

Optimizations and first content pieces

On-site optimizations continue, internal linking is restructured and the first optimized content pieces are published. The site structure improves, and Google starts recrawling and reassessing your pages.

3
Month 3

First visible results

Link building kicks off, and published content starts ranking. This is usually the stage where the first clear improvements appear: that is why we recommend at least 3 months to judge the retainer.

4
Months 4 to 6

Growth phase

Content and link building ramp up. Your rankings improve on increasingly competitive queries, and qualified traffic and conversions follow.

5
Month 6 and beyond

Consolidation and expansion

We defend the rankings we have earned, expand into new semantic territory, and SEO becomes firmly established as your most profitable acquisition channel.

What's included every month

Three axes worked on in parallel, every month, by the same team. Bring in customers from Google and AI assistants, keep a structured, fast and secure site so every page gets the authority it deserves, and steer it all with you. No hidden extras: everything below is included.

Axis 1

Bring in customers

  • SEO content production

    Writing and publishing every month: service pages, articles, local pages. Every piece of content targets a search intent that generates revenue, not just traffic. Brief, writing, publishing: we handle it all.

  • Progressive link building

    Steady acquisition of editorial backlinks from sites with real organic traffic. A link profile that gets stronger month after month, naturally and sustainably. No shady networks, no penalty risk.

  • GEO: visibility in AI answersIncluded

    ChatGPT, Perplexity, Claude, Gemini: we measure where you are cited and optimize your content to be the source AI models recommend. GEO is part of the retainer, not an add-on.

Goal: more enquiries, from Google and from AI assistants

Axis 2

Keep the site solid

  • Internal linking worked on every monthIncluded

    Every new piece of content is connected to the pages that need to sell, and your strategic pages receive links from across the whole site. It is the most underrated lever in SEO: it distributes the authority of your backlinks to the right pages and helps Google understand what matters on your site.

  • Ongoing technical optimization

    Indexing monitoring, crawl error fixes, speed and structure optimization. Google keeps changing its criteria: your site stays up to standard all year round, not just the month of the audit.

  • Site security and maintenanceIncluded

    CMS and plugin updates, regular backups, HTTPS, uptime monitoring and protection against common attacks. A site that goes down or gets hacked loses its rankings: we make sure it doesn't happen.

Goal: a structured, fast and secure site that pushes the right pages

Axis 3

Steer it with you

  • Strategy and roadmap

    Built to measure after the initial audit, then updated every month based on your results and your business priorities. No random actions: every month has a clear objective.

  • A monthly video call

    Results, the past month's actions, next month's priorities. You ask your questions, we adjust together. You are never left in the dark.

  • Transparent monthly reporting

    Rankings, organic traffic, conversions, AI citations, completed actions, next steps: numbers that speak business, not jargon.

Goal: you always know what we are doing and what it delivers

Zero commitment: one month's notice is all it takes to stop. You stay for the results, not for the contract.

Is this retainer right for you?

We would rather be upfront: the monthly retainer is not a fit for everyone. Here is how to know if we will work well together.

✓ Go for it if

  • You want SEO to become a lasting acquisition channel, not just "being on Google"
  • You have a site that works and you want it to generate more leads or sales
  • You would rather delegate to experts than learn SEO on the job
  • You are looking for a transparent partner who shows you what has been done each month
  • You are ready to invest several months: SEO rewards consistency

✕ Skip it if

  • SEO is your last resort: if your business's entire survival depends on this investment, the partnership starts on shaky ground. We never bet everything on one horse
  • You are looking for results in 2 weeks: SEO does not work like paid advertising
  • Your website matters less than other channels in your business model
  • You just want a one-off audit: in that case, our SEO Audit offer is a better fit
  • You are not able to validate content or implement the things that depend on you
  • Your budget cannot sustain at least 3 months: better to wait for the right time

What does a monthly SEO retainer cost?

The price of an SEO retainer depends on three factors: the size of your site, how competitive your market is and the volume of work needed each month to hit your goals. Here are the ranges typically seen on the French market for a monthly SEO package.

Business profile Indicative monthly budget Type of work
SMB / service business €800 to €2,500 / month Full strategy, regular content, targeted link building
E-commerce / competitive market €1,500 to €4,000+ / month High content volume, sustained link building, advanced technical work

€1,200 / month

That is what our clients invest on average in their monthly SEO retainer, excluding backlink purchases. The link-building budget is added according to your market: we price it with you, separately, and you see every link purchased.

Be wary of cut-rate SEO retainers at €150 or €200 a month: at that price, no serious provider can produce quality content, earn real links and track your results. At best you are paying for nothing, at worst for tactics that put your site at risk of a Google penalty. A custom SEO retainer quote, tailored to your actual goals, remains the best starting point.

Monthly SEO or Google Ads: which one for your acquisition?

Both bring in customers, but not in the same way. Advertising rents visibility; SEO builds an asset that belongs to you.

Criterion Monthly SEO retainer Google Ads
Cost Fixed monthly budget, no cost per click Every click is paid for, and the cost rises with competition
Time to results First results around month 3 Traffic as soon as the ads go live
If you stop The rankings you have earned keep generating traffic Traffic stops the day the budget stops
Asset built Content, authority and rankings that belong to you None: you are renting visibility
Best for A lasting, profitable acquisition channel A launch, a promotion or testing an offer fast

What our clients say

Frequently asked questions

What is a monthly SEO retainer and who is it for?

It is an ongoing SEO engagement where an agency or consultant manages your search visibility every month: strategy, technical work, content, link building and reporting. It is for any business that wants to turn Google into a lasting acquisition channel: SMBs, e-commerce, freelancers, service businesses.

How does a monthly SEO retainer actually work?

It starts with an audit that leads to a prioritized roadmap. Then, every month: technical optimizations, publication of optimized content, internal linking, backlink acquisition, tracking of your visibility in AI answers (GEO), site maintenance and security, a video call and detailed reporting. The strategy is continuously adjusted based on the results observed.

What does a monthly SEO retainer cost?

The price of an SEO retainer depends on your site's size, how competitive your market is and the volume of work required. Expect between €800 and €2,500 per month for an SMB or service business, and between €1,500 and €4,000+ for e-commerce in a competitive market. On average, our clients invest €1,200 per month, excluding backlink purchases. Request a custom quote for precise pricing.

What is the difference between an SEO retainer and an SEO audit?

An SEO audit is a one-time snapshot: it identifies the issues and delivers an action plan. A monthly SEO retainer goes further: it executes that plan, produces content, builds links and adjusts the strategy month after month. The audit says what to do, the retainer does it.

Is an SEO retainer really worth it for an SMB?

Yes, provided you think long-term. Unlike paid advertising, which stops the moment you cut the budget, SEO traffic keeps generating leads with no cost per click. Our SMB clients typically see an acquisition cost 30% lower than paid channels after 6 to 12 months.

Does the monthly SEO retainer work for e-commerce?

Yes, it is actually one of the most profitable use cases. For an online store, the monthly SEO retainer works category pages as landing pages, unique product pages, faceted navigation, product structured data and the linking between products and buying guides, at scale. Expect between €1,500 and €4,000+ per month depending on the catalogue and the competition. Example: 1001 Tirelires, a Shopify store started from scratch, reached 144,000 impressions and 1,910 clicks in one year. The details of our method are on the e-commerce SEO agency page.

Do you also offer local SEO retainers?

Yes. We optimize your Google Business Profile, your local pages and the geo-targeted queries that generate quote requests in your area, alongside the rest of the strategy.

How long before you see results from a monthly SEO retainer?

The first technical fixes and optimizations can move rankings within the first few weeks. Clear results usually arrive around month 3, when the published content starts ranking and link building kicks off. Between months 4 and 6, qualified traffic and enquiries follow. That is why we recommend at least 3 months to judge the retainer.

Monthly SEO or Google Ads: which should you choose?

Google Ads brings immediate traffic, but every click is paid for and everything stops when the budget stops. Monthly SEO takes a few months to take off, but builds a lasting asset: the rankings keep generating customers with no cost per click. Many businesses combine both: Ads to get started, SEO to bring the cost of acquisition down for good.

How do you choose an agency for a monthly SEO retainer?

Check four things: case studies with real numbers on sites comparable to yours, detailed deliverables every month (not a vague offer), business-oriented reporting (enquiries, sales, not just rankings) and no long-term commitment. Be wary of €150-a-month packages: at that price, nobody is really working on your site.

Does the SEO retainer work with WordPress, Wix or Shopify?

Yes, the retainer adapts to your CMS: WordPress (with or without Elementor), Wix, Shopify, Webflow or a custom-built site. Our case studies actually include a Wix site and a WordPress + Elementor site. If your platform has technical limitations, we tell you during the audit.
