Technical maintenance is the foundation of SEO, not an extra
A website without regular technical checks gathers small problems - slower loading, broken links, outdated plugins - that are barely noticeable one by one but together steadily drag down its rankings in Google.
Website technical maintenance is an ongoing process that keeps a website technically healthy and protects its SEO positions in Google. In 2026 it includes several specific components: monitoring the reliability of your infrastructure, maintaining hreflang on multilingual websites, keeping Core Web Vitals in shape for mobile visitors, accessibility (WCAG) and compliance with technical requirements.
Website support: what technical maintenance involves
This guide is for website owners and marketers: what website support and administration involve, how often each task should be done and how to set up monitoring of your website's technical health.
Regular technical tasks for a website
Daily website monitoring
Uptime monitoring: tools such as UptimeRobot (free plan: checks every 5 minutes, alerts by email, SMS or Slack) or Pingdom, which checks availability from several locations. Essential for any website that brings in enquiries or sales.
Google Search Console alerts: GSC automatically notifies you of critical problems (manual actions, critical indexing errors, security issues). Make sure the notifications go to an email address that someone actually reads.
Cloudflare/CDN status: if your website uses Cloudflare (standard for many websites), keep an eye on the CDN status and caching rules so visitors are not served outdated cached pages.
Weekly technical tasks for a website
Checking the Pages report in Google Search Console: new indexing errors, pages moving from "Indexed" to "Not indexed" and new warnings. A weekly look at this report stops unnoticed technical problems from building up.
Core Web Vitals monitoring: the Core Web Vitals report in GSC updates with a delay of around 28 days, but PageSpeed Insights can be checked weekly for key pages (the home page and the top 5 landing pages by traffic).
Hreflang checks for language versions: on multi-regional websites (for example, en-GB, en-AU and fr), a weekly spot check of hreflang with an hreflang testing tool or Screaming Frog. Hreflang errors can cause language versions to drop out of Google's index.
Monthly technical tasks
CMS updates: Joomla, WordPress and Drupal release security updates regularly. Update to the latest stable version (after taking a test backup first). Crucially, websites without CMS updates are vulnerable to hacking, which can lead to Google penalties (spam or security issues).
The domain's SSL certificate: Let's Encrypt certificates are valid for 90 days. Automatic renewal through Certbot should be configured. A monthly check of the certificate status prevents unexpected expiry, which triggers browser warnings for visitors.
Keeping the sitemap up to date: for websites with frequently changing content (blogs, news sites), sitemap.xml should update whenever pages are added. Monthly check: all new pages are in the sitemap and the lastmod dates are current.
Broken link audit: a monthly check for 404 errors in the GSC Pages report or Screaming Frog. Internal links to 404 pages reduce how efficiently Google crawls your website.
AI crawler access
Once a month, check that a hosting update, bot protection or a new plugin has not blocked the ChatGPT, Perplexity or Google AI crawlers. The website keeps working, but it drops out of AI answers - and without a check that is almost impossible to notice. Check both robots.txt and the server's actual response.
Technical tasks for websites serving several markets
Reliability and compliance
For international websites in 2026:
Website backups: regular backups (files + database) to separate cloud storage. For WordPress or Joomla websites: automated daily backups through the hosting panel or plugins (UpdraftPlus for WordPress, Akeeba Backup for Joomla).
Monitoring email for your domain: business email on your domain should be monitored for deliverability. Problems with MX, SPF, DKIM or DMARC records disrupt business communication and indirectly affect your online presence.
Keeping your Google Business Profile current: for local businesses, the Google Business Profile is a key SEO tool. Maintenance includes keeping opening hours accurate, replying to Google reviews and refreshing photos.
Technical monitoring of hreflang
Hreflang on multi-regional websites needs ongoing technical monitoring:
Reciprocal hreflang: every language version must point to all the other versions, and each of those must link back. Broken reciprocity is a common reason for language versions being deindexed.
Hreflang for new pages: when you add a new article to one version, matching hreflang tags must be added to every language version of the website. Missing hreflang on new pages creates inconsistencies.
Consistent canonical URLs: canonical tags must match the hreflang href values. A mismatch between canonical and hreflang sends Google conflicting signals.
Technical tools for SEO monitoring
Free tools for technical monitoring
Google Search Console: the main free tool for monitoring a website's technical health. Page indexing, Core Web Vitals, manual actions, security issues.
Google PageSpeed Insights: a free Core Web Vitals check for individual URLs. Use it to monitor your key landing pages.
UptimeRobot: free uptime monitoring (up to 50 monitors, checks every 5 minutes). Alerts by email, SMS or Slack.
Paid tools for technical audits
Screaming Frog SEO Spider: crawls the website to find technical problems (broken links, redirect chains, hreflang errors, duplicate content, thin content). Once a month for large websites.
Ahrefs Site Audit: an automated technical website audit with prioritised issues and fix recommendations. Well suited to agencies managing several client websites.
What website support costs
The monthly cost of website support depends on the scope: backups and monitoring for a small website take 30-60 minutes of work a month, while looking after a large online shop with updates and integrations is a separate contract with a developer.
In the GEO SEO marketing plans website support is already included: a backup, restore on request and help with the technical side of the website, plus a monthly check of SEO and AI crawler access.
FAQ: website technical maintenance
How often should a website's CMS be updated? Security updates - as soon as they are released. Minor feature updates - within 2-4 weeks. Major versions (Joomla 3.x -> 4.x, WordPress 5.x -> 6.x) - after testing on a staging site. Websites that are not updated regularly are a common target for automated hacks.
What should I do if Google flags a "Security Issue" for my website in GSC? Immediate steps: 1) Back up the current state of the website, 2) Scan it for malware (Sucuri SiteCheck, MalCare), 3) Remove the malicious code, 4) Change all admin passwords, 5) Update the CMS and plugins, 6) Request a review in GSC once the website is clean. Security issues in GSC directly reduce your website's visibility in Google.
Does a small website (5-10 pages) need technical maintenance? Yes, on a smaller scale. A small website needs SSL monitoring, monthly CMS updates, GSC monitoring for critical errors and uptime monitoring with UptimeRobot. It takes 30-60 minutes a month but prevents serious technical problems.
Conclusion: technical maintenance as the foundation of SEO
Website maintenance is invisible work that only gets noticed when it is missing. Websites without regular maintenance build up technical debt: an outdated CMS with vulnerabilities, broken links, faulty hreflang, slow Core Web Vitals and indexing problems. Each of these has a moderate effect on Google rankings on its own; together they can cause a serious drop in traffic, which often goes unnoticed without monitoring.
