If you are paying every month, you should know what is being checked, what is being fixed, what is being improved and how it connects to commercial performance.
Too many retainers become vague. You receive a report, a few ranking movements, maybe a list of technical issues, and not much clarity on what has actually changed. That is not good enough.
A good technical SEO retainer should be practical, prioritised and tied to business outcomes. It should help your website stay crawlable, fast, clean, measurable and able to support growth.
This matters because your website is not static. Content changes. Developers push updates. Tracking breaks. Competitors improve. Search results shift. AI search changes how brands are discovered. A one-off audit can help, but it will not protect performance forever.
For UK businesses, the stakes are high. IAB UK reported that the UK digital advertising market reached £40.5bn in 2025, up 10% year on year, which shows how much competition there is for digital attention. (IAB UK) ONS data also showed online sales made up 28.7% of total retail sales in Great Britain in March 2026, so digital journeys remain central to how people research, compare and buy. (Office for National Statistics)
That is why a technical SEO retainer should not just monitor your website. It should actively improve it.
It Should Start With A Clear Technical Baseline
Before month-to-month work begins, you need a clear baseline.
That means understanding the current state of your website, not just running an automated crawl and sending over a PDF. A proper baseline should explain what is working, what is holding the site back and what should be fixed first.
This usually includes:
- Crawlability: Can search engines access the pages that matter?
- Indexation: Are the right pages indexed and the wrong pages excluded?
- Site Structure: Is the hierarchy clear for users and search engines?
- Internal Linking: Are important pages supported properly?
- Page Speed: Are templates loading quickly enough?
- Core Web Vitals: Are user experience metrics creating risk?
- Canonicals: Are duplicate or similar pages handled correctly?
- Redirects: Are redirects clean, relevant and not wasting crawl budget?
- Schema: Is structured data present, valid and useful?
- Tracking: Are conversions and events being measured properly?
This is where working with a seo audit agency London can help. The audit should set the priority list for the retainer, so every month has a purpose rather than becoming a random set of small fixes.
It Should Include Monthly Crawl And Indexation Checks
Your website can develop technical issues without anyone noticing.
A new page template may block content from being crawled. A staging rule may accidentally carry over. A plugin update may change canonical tags. A developer may remove internal links. A CMS change may generate duplicate URLs.
That is why monthly crawl and indexation checks should be part of a serious technical SEO retainer.
The work should cover:
- Crawl Errors: Finding broken pages, blocked assets and server issues.
- Indexation Gaps: Checking whether important pages are indexed.
- Noindex Tags: Making sure they are used only where intended.
- Canonicals: Checking whether pages point to the right version.
- Sitemap Health: Reviewing submitted URLs and errors.
- Robots.txt: Making sure search engines are not blocked incorrectly.
- Duplicate URLs: Finding variants that waste crawl budget.
- Redirect Chains: Removing unnecessary steps.
This work is not glamorous, but it protects performance.
If your site has hundreds or thousands of pages, regular checks are even more important. Small technical problems can scale quickly and affect large sections of the site.
Totally Digital’s technical SEO agency service is relevant here because technical SEO is not just about fixing visible errors. It is about making sure the site remains accessible, efficient and understandable as it grows.
It Should Prioritise Issues By Business Impact
Not every SEO issue deserves the same attention.
A missing meta description on an old blog post may not matter much. A noindex tag on a lead-generating service page matters a lot.
A good retainer should separate technical noise from commercial risk.
Each month, recommendations should be prioritised by:
- Revenue Impact: Does this affect pages that generate enquiries or sales?
- Search Demand: Does this affect pages with ranking potential?
- Traffic Risk: Could this harm existing organic performance?
- Development Effort: Is the fix simple or complex?
- User Impact: Does this make the website easier or harder to use?
- Strategic Value: Does this support long-term growth?
This is the difference between a useful retainer and a checklist retainer.
A checklist retainer says, “You have 247 issues.”
A useful retainer says, “These 6 issues are affecting your most important commercial pages, and this is the order we should fix them in.”
If you are working with technical seo agencies, this prioritisation should be visible every month.
It Should Support Content And Page Performance
Technical SEO is not separate from content.
If your pages are slow, poorly structured, thin, duplicated or internally isolated, content performance will suffer. A good retainer should therefore look at how technical issues affect content visibility.
This may include:
- Thin Pages: Identifying pages that do not answer intent properly.
- Cannibalisation: Finding pages competing for similar terms.
- Orphan Pages: Finding useful content with no internal links.
- Heading Structure: Checking whether page hierarchy is clear.
- Internal Links: Improving connections between related pages.
- Content Decay: Spotting pages losing traffic or rankings.
- Template Limits: Checking whether page templates restrict useful content.
This is where technical SEO and organic strategy need to work together. An organic marketing company should not only recommend new content. It should also help existing pages perform better by improving structure, relevance and internal linking.
For example, an article that ranks on page 2 may not need a full rewrite. It may need better internal links, clearer headings, updated FAQs and stronger links to a relevant service page.
Totally Digital’s insight on on-page SEO for service pages is useful here because service pages need to satisfy both search engines and potential customers.
It Should Include Internal Linking Improvements
Internal linking should not be treated as a one-off task.
As your website grows, new pages need support. Older articles may need links to newer services. Important pages may become buried. Blog content may attract traffic but fail to guide users towards enquiry.
A monthly technical SEO retainer should review internal links regularly.
This means checking:
- Hub Pages: Are important service areas supported by related content?
- Anchor Text: Is link text clear, natural and varied?
- Click Depth: Are key pages too far from the homepage?
- Orphan Content: Are useful pages disconnected from the wider site?
- Commercial Pages: Are service pages receiving enough contextual links?
- Blog Journeys: Do insight articles guide users to relevant next steps?
A good internal linking strategy helps search engines understand relationships between pages. It also helps users continue their journey instead of reaching a dead end.
Totally Digital’s guide to internal linking audits is a strong example of the kind of practical work that should sit inside an ongoing retainer.
It Should Monitor Website Speed And Core Web Vitals
Page speed is not something you fix once and forget.
New scripts, plugins, images, embeds, tracking tags and design changes can all slow a website down over time.
A technical SEO retainer should keep an eye on performance every month, especially for key templates such as:
- Homepage.
- Service pages.
- Blog posts.
- Landing pages.
- Contact pages.
- Product or category pages.
- Location pages.
The work should include reviewing Core Web Vitals, large images, render-blocking resources, unnecessary scripts, third-party tags and mobile performance.
This matters for SEO, but it also matters for conversions. If users have to wait too long, some will leave before they enquire.
Totally Digital’s Core Web Vitals deep dive is useful if your site has performance issues across multiple templates or a large number of pages.
It Should Include Developer-Ready Recommendations
A technical SEO retainer should not simply point out problems.
It should make fixes easier to implement.
That means recommendations should be written in a way your developers can understand and act on. If a fix requires development time, the SEO team should explain the issue, the expected outcome, the affected URLs and the preferred implementation.
Developer-ready recommendations may include:
- Issue Summary: What is wrong and why it matters.
- Affected URLs: Which pages or templates are involved.
- Priority Level: How urgent the fix is.
- Recommended Fix: What should be changed.
- Acceptance Criteria: How the fix will be checked.
- SEO Impact: What the change should improve.
- Risk Notes: What to avoid during implementation.
This prevents confusion between marketing, SEO and development teams.
It also saves time. Instead of vague instructions such as “improve crawlability”, your developers get a clear task they can build, test and release.
Totally Digital’s article on SEO specs for developers is highly relevant here because technical SEO often fails when recommendations are not translated into practical development tasks.
It Should Review Tracking And Reporting Quality
Technical SEO is not only about search engines. It is also about whether you can measure what is happening properly.
If your analytics setup is weak, you may make poor decisions.
For example, you may think a page is underperforming when the real issue is broken event tracking. You may think a channel is driving leads when the enquiries are low quality. You may miss calls, booking clicks or form errors because they are not tracked properly.
A good monthly retainer should include checks around:
- GA4 Events: Are key actions being tracked?
- Form Submissions: Are they firing correctly?
- Phone And Email Clicks: Are high-intent clicks captured?
- Thank-You Pages: Are they working as expected?
- Consent Mode: Is tracking aligned with privacy requirements?
- Tag Governance: Are tags named, tested and managed properly?
- Dashboard Accuracy: Are reports showing useful data?
This matters because SEO reporting should not stop at rankings and traffic. It should show whether organic visibility is helping the business.
Totally Digital’s GA4 event strategy and Google Tag Manager governance resources are useful examples of the measurement work that supports better SEO decisions.
It Should Connect SEO With Paid Media
A technical SEO retainer should also support other marketing channels.
If you are running paid campaigns, poor site speed, broken tracking, weak landing pages or unclear user journeys can waste budget.
UK digital ad spend continues to grow, so businesses need to make sure paid traffic is not being sent to pages with technical or UX problems. IAB UK reported the UK digital ad market reached £40.5bn in 2025, showing how competitive paid channels have become. (IAB UK)
A paid advertising agency will get more from campaigns when landing pages are technically sound, fast, trackable and aligned with user intent.
A retainer can support this by checking:
- Landing Page Speed: Are campaign pages loading quickly?
- Tracking: Are conversions attributed correctly?
- Form Functionality: Are paid leads being captured reliably?
- Message Match: Does the page match the ad promise?
- Indexation Rules: Should paid-only pages be indexed or excluded?
- Experimentation: Are tests measured cleanly?
This is where SEO, paid media and analytics should work together rather than compete for attention.
Totally Digital’s article on PPC landing pages that convert is useful if your paid campaigns rely on service-led landing pages.
It Should Prepare The Site For AI Search And GEO
Technical SEO is changing because search behaviour is changing.
Traditional rankings still matter, but more users are also relying on AI-generated answers, summaries and recommendations. This means websites need clear structure, trusted content, useful FAQs, schema and strong external signals.
A monthly retainer should start considering how your content and site architecture support AI discovery.
This may include:
- Entity Clarity: Making services, locations, people and expertise easy to understand.
- Structured Data: Adding schema where it genuinely helps.
- FAQ Quality: Answering real questions clearly.
- Source Signals: Improving credibility and citation potential.
- Content Structure: Making pages easier to summarise.
- Brand Consistency: Ensuring your services are described consistently across the web.
A geo agency london can help you look beyond traditional rankings and improve how your brand appears in AI search and answer engines.
Totally Digital’s service page explains that generative engine optimisation focuses on improving your chances of being named, linked or quoted in AI-generated answers, not only ranking in standard search results. (Totally Digital)

It Should Include Clear Monthly Reporting
A good technical SEO report should not be a data dump.
It should explain what was done, what changed, what matters and what happens next.
Each monthly report should include:
- Work Completed: What actions were taken that month.
- Technical Changes: What issues were fixed or escalated.
- Performance Movement: What changed in traffic, rankings or conversions.
- Risks Found: What needs attention soon.
- Development Tasks: What requires developer support.
- Content Opportunities: What pages need updates or internal links.
- Next Priorities: What will be worked on next month.
- Commercial Context: How the work supports enquiries, sales or visibility.
The report should be easy for marketing teams, directors and developers to understand. You should not need to decode SEO jargon to see whether progress is being made.
If the report does not help you make decisions, it needs to be improved.
What A Good Month-To-Month Retainer Looks Like
A strong technical SEO retainer usually includes a rhythm like this:
- Month Start: Review performance, search visibility, conversions and known issues.
- Technical Crawl: Check crawlability, indexation, redirects, canonicals and errors.
- Priority Fixes: Complete or brief the most important technical tasks.
- Content Support: Identify content improvements, internal links and structural gaps.
- Tracking Review: Check key events, forms and reporting accuracy.
- Developer Support: Provide clear instructions for technical fixes.
- Competitor Review: Check whether competitors are gaining visibility in priority areas.
- Reporting: Summarise actions, results, risks and next steps.
- Planning: Set priorities for the next month.
This kind of rhythm keeps the retainer active and accountable. It also means SEO is not waiting for problems to become serious before acting.
FAQs
What should a technical SEO retainer include?
A technical SEO retainer should include regular crawl checks, indexation monitoring, site speed reviews, Core Web Vitals checks, internal linking improvements, technical recommendations, tracking checks, reporting and developer support. It should also prioritise issues based on commercial impact, not just technical severity.
How often should technical SEO be reviewed?
Technical SEO should be reviewed every month for most active business websites. Larger sites, eCommerce sites or websites with frequent development changes may need more regular checks. Search performance can be affected by small changes, so ongoing monitoring helps prevent avoidable problems.
Is a one-off SEO audit enough?
A one-off audit is useful, but it is not enough if your site changes regularly or operates in a competitive market. An audit gives you the starting point. A retainer helps you implement fixes, monitor changes, respond to issues and keep improving performance over time.
Should technical SEO include content recommendations?
Yes, technical SEO should often include content recommendations because technical structure and content performance are closely connected. Issues such as thin pages, cannibalisation, weak internal linking and poor heading structure can affect how well content performs in search.
How do you know if a technical SEO retainer is working?
You know it is working when technical issues are being reduced, important pages are becoming easier to crawl and index, site speed is improving, tracking is reliable, rankings and traffic are moving in the right direction, and organic activity is supporting better-quality enquiries or sales.
Final Thoughts
A good technical SEO retainer should be clear, active and commercially useful.
It should not only tell you what is wrong. It should help you decide what matters, fix what is holding the site back and improve performance month by month.
The best retainers bring together technical SEO, content, analytics, UX, development and commercial priorities. That is how you move beyond reports and start making real progress.
