I worked with WordPress for years. I built dozens of WP sites, installed themes, optimised plugins, fought with updates that broke the site, fought comment spam, configured backups, cleaned hacked sites… and I migrated to Astro in 2023. In this article I tell you why, with real data, and when WordPress is still a valid option.
TL;DR
- Astro is a modern static site framework (with interactive islands) that loads in under 1 second, has SEO and GEO built in, and does not break with updates.
- WordPress is a very mature CMS with 20 years of plugins and themes, ideal if you need non-technical staff to edit content daily and you are willing to invest time (or money) in maintenance.
- For a corporate site or landing page that prioritises speed, SEO and low maintenance, Astro is the better option in 2026.
- For a blog with 5+ writers or a shop with thousands of products, WordPress + WooCommerce is still the most pragmatic option.
Loading speed: the difference is brutal
I have measured the same website with real data on PageSpeed Insights and GTmetrix. Same connection, same server, same content:
| Metric | Typical WordPress | Astro (my site) |
|---|---|---|
| Lighthouse load time | 2.5-4.5 s | 0.6-1.0 s |
| LCP (Largest Contentful Paint) | 2.0-3.5 s | 0.7-1.2 s |
| CLS (Cumulative Layout Shift) | 0.05-0.3 | 0.0-0.05 |
| TBT (Total Blocking Time) | 200-800 ms | 0-50 ms |
| Initial JS | 500 KB - 1.5 MB | 0 - 50 KB |
| Core Web Vitals | 60-80 | 95-100 |
And this is not cherry-picking: on my corporate website, before migrating, PageSpeed gave me 71. After migrating to Astro, 98. Without touching the design, no trick. The difference is that WordPress runs PHP on every request, loads jQuery, the WooCommerce library if you have it, your theme, your plugins, your shortcodes, your widgets… and all of that adds up.
Astro, on the other hand, generates static HTML at build time and serves it directly. Your page is an HTML file with minified CSS. No database, no PHP, no execution time. The browser paints it in milliseconds.
SEO: Google notices
Google does not explicitly penalise speed, but it uses it as a ranking signal (Core Web Vitals have been a ranking factor since 2021). On top of that, a fast site has a better conversion rate: according to data from Google and Vodafone, every 100 ms improvement in LCP raises conversions by 2-4%.
On my projects migrated to Astro I have seen:
- +20-40% organic traffic in the first 3-6 months (not only because of the speed, also because of the cleaner semantic structure).
- Better ranking on competitive keywords because pages load before the user leaves.
- Better ad conversion rate: Google Ads Quality Score goes up when the landing page loads fast, and that lowers the CPC.
Maintenance: peace of mind
This is what my clients value most after migrating. The “maintenance” difference between WordPress and Astro is huge:
WordPress: what you have to do every month
- Update WP core (sometimes breaks things)
- Update plugins (sometimes breaks things)
- Update theme (sometimes breaks things)
- Renew SSL certificate
- Clean database (transients, post revisions, spam)
- Check access logs for hacking attempts
- Update PHP versión on the server
- Back up and verify they can be restored
- Install/update security plugins (Wordfence, Sucuri)
- Fight comment spam (even with Akismet)
- Manage GDPR cookies (another plugin)
- Configure SMTP for the contact form
- Cache (another plugin: WP Super Cache, W3 Total Cache, LiteSpeed Cache…)
- Optimise images (another plugin: Smush, ShortPixel, Imagify…)
That is 10-15 critical plugins and each one is an attack vector and a possible breaking point. A WordPress left unmaintained for 6 months is a ticking time bomb: it will have 3 known vulnerabilities and 8 outdated plugins for sure.
Astro: what you have to do every month
- Nothing.
Really. The site is a set of static HTML/CSS/JS files served by a CDN. There is no database to hack, no plugins to update, no PHP that can break. If you do not change content, you do not have to touch anything for months.
If you want to edit content, there are two options:
- Custom CMS based on JSON or Markdown files (what I use in my restaurant and clinic projects). The client edits the JSON, I do a 30-second redeploy, and that is it.
- Headless CMS (Sanity, Contentful, Storyblok). The client edits in a visual interface, it publishes via API, and the site regenerates automatically.
Total cost over 3 years: the bill nobody does
Here is the data that hurts the most to those who choose WordPress thinking it is “cheaper”:
| Item | WordPress | Astro |
|---|---|---|
| Initial design + development | EUR 1,500-5,000 | EUR 600-2,000 |
| Annual hosting | EUR 100-300 | EUR 0-50 |
| Monthly maintenance (me or a pro) | EUR 80-200/mo | EUR 0-50/mo (optional) |
| Plugin/theme renewal | EUR 50-200/yr | EUR 0 |
| Cleanup after hack (avg every 2-3 years) | EUR 200-800 | EUR 0 |
| Time spent by client on maintenance | 2-5 h/month | 0-1 h/month |
| 3-year total | EUR 6,000-15,000 | EUR 600-3,500 |
It is not a joke. WordPress ends up more expensive in the medium term almost always, especially if you add the opportunity cost of the hours you lose maintaining the site instead of running your business.
When WordPress is still a good option
It is not all black and white. There are cases where WordPress is still the best option:
- Blog with 5+ writers who need a visual Word-like editor. Better a WordPress with good hosting than a complex headless CMS.
- Large online store (thousands of products, many attributes, real-time stock). WooCommerce is still king, although performance is debatable.
- Membership site / LMS with specific plugins (LearnDash, MemberPress). Reimplementing all that in Astro would be reinventing the wheel.
- Client who does not want or cannot pay for a migration and the current WP site “works, do not touch it”.
In those cases, what I do is: leave the site on WP, optimise it to the max (good theme, minimal plugins, decent hosting, aggressive cache), and be very clear with the client about the maintenance cost.
When to migrate from WordPress to Astro
If your current WP site:
- Loads in over 2.5 seconds on mobile
- Has more than 15 installed plugins
- You have not updated the core in 6+ months
- You have been hacked at some point
- Costs you 100+ EUR/month in maintenance
- Does not rank as well as it should
- Is edited by non-technical people, but they are willing to use an alternative CMS
…then it is worth migrating. The process is transparent: I keep your URLs, your SEO, your content, your links. The site looks the same or better visually, and goes on to load in under 1 second. I send you a fixed-price quote in writing within 24 hours after reviewing your case.
Conclusión
I am not telling you to migrate to Astro “just because”. I am telling you that, in 2026, for a corporate site, landing or portfolio, Astro is objectively a better option than WordPress in speed, SEO, maintenance, security and total cost. And for the cases where WordPress is still the best option (large shop, blog with many writers), I tell you that in the first call, without trying to sell you something you do not need.
If you want me to look at your specific case, write to me or by WhatsApp and we review your current site with no commitment.
