WordPress and SEO: a solid foundation, often poorly configured
The WordPress CMS doesn’t hurt SEO; quite the opposite. It produces readable URLs through permalinks, generates an XML sitemap, handles title tags and gives you control over nearly all the code sent to the browser. A large part of the web runs on it, and Google crawls it with no trouble.

The problems come from elsewhere: settings left at their defaults, a theme bought for its looks rather than for being lightweight, plugins added as needs came up and never removed, shared hosting that responds slowly. Each of these choices seems harmless; added together, they slow pages down, multiply duplicate URLs and blur what the site is trying to show.
WordPress SEO therefore means applying the principles of search engine optimization, described on our SEO agency page, with a working knowledge of how the CMS operates: how it creates archives, the order in which plugins load, the reading settings, the theme’s template hierarchy.
Typical issues on a WordPress site
This table brings together the problems we see most often on WordPress sites, where they usually come from and the right fix.
| Symptom | Common cause | Fix |
|---|---|---|
| Archive pages indexed in bulk | Tags, authors, dates and, on sites installed before WordPress 6.4, attachment pages left open to search engines | Noindex or redirect archives with no value, keep the useful categories |
| Duplicate content | URL parameters, comment reply URLs (?replytocom), versions with and without www or a trailing slash | Canonical tags, 301 redirects and single-URL rules |
| Entire site missing from Google | Visibility box left checked after launch, overly strict robots.txt | Check of reading settings and the robots.txt file, indexing request |
| Duplicate or conflicting title tags | Two active SEO plugins, or a theme that writes its own tags | A single SEO plugin, theme settings neutralized |
| Redirect chains | Repeated changes to permalinks or structure | Direct redirects to the final URL, internal links updated |
| Slow pages on mobile | Heavy page builder, plugin scripts loaded everywhere, no caching | Caching, a lighter theme, conditional script loading |
| Language versions poorly linked | Incomplete WPML or Polylang setup | Verified hreflang tags, one URL per language, translated menus |
SEO plugins, themes and page builders
Yoast, Rank Math: just one, properly configured
An SEO plugin doesn’t rank a site for you; it gives you access to settings WordPress doesn’t offer out of the box: titles and descriptions per page, indexing rules by content type, a filtered sitemap, breadcrumbs, structured data. Yoast SEO and Rank Math do this job in comparable ways. Which one you pick matters less than how it’s configured, and above all that there’s only one: two plugins writing the same tags produce contradictory pages. And the green score shown in the editor measures whether a word appears in the text, not the quality of a page.
The weight of page builders
Visual builders like Elementor or Divi make layout easier, but they add code, stylesheets and scripts to every page. The native Gutenberg editor, which is lighter, is often enough for content pages. We don’t recommend rebuilding everything: we measure what the builder costs on your key templates and suggest possible ways to lighten the load, from asset-loading settings to replacing a few templates.
The plugin inventory
Every plugin is a potential source of slowdowns, conflicts or security holes. We list the ones installed, what they actually do and when they were last updated, then suggest what can be deactivated, replaced or consolidated. Nothing is removed without your approval.
Speed and Core Web Vitals on WordPress
Google takes page experience into account through three metrics: LCP for how fast the main content displays, INP for responsiveness and CLS for visual shifts during loading. On WordPress, the same causes keep coming up: images served at their original size, fonts loaded from several servers, chat, analytics or carousel scripts running on every page, and a server that’s slow to respond.
The fixes are well known; the challenge is applying them in the right order without breaking the site: page caching, compression and modern formats like WebP for images, an up-to-date PHP version, database cleanup, deferred loading of non-essential scripts. Hosting sometimes makes all the difference; when it’s holding the site back, we say so. Each template is measured before and after with PageSpeed Insights and real-world data from Search Console.
Content, structure and AI search
A technically clean site won’t rank without pages aligned with what your customers search for. We identify the queries to target, then organize the site accordingly. Categories reflect real topics, pillar pages are linked to their articles, internal linking leads to the sales pages and subheadings are written for the reader. Author and About pages are fleshed out to show who’s writing and with what experience, which Google groups under its E-E-A-T criteria.
Chat assistants, from ChatGPT to Perplexity, and Google’s AI Overviews read the same pages. Clear answers at the start of each section, valid structured data and consistent information from one page to the next help them pick up your content. We cover this approach in a dedicated guide to Generative Engine Optimization.
Some sites need special treatment. A WooCommerce store adds product pages, filters and variations, which we handle in our ecommerce SEO services. A multilingual site falls under international SEO, and a business that relies on nearby customers benefits from adding local SEO.
Redesigns, theme changes and migrations
Switching themes, moving to a page builder, migrating the site to a new domain or another host: these are the moments when a WordPress site most easily loses its rankings. URLs change, pages disappear, tags get reset, and traffic drops without anyone knowing why.
Before the operation, we record every URL that receives visits or links, and we prepare the 301 redirect map following Google’s guidelines on site moves. On the staging copy, we check titles, canonical tags, indexing rules and structured data. After the switch, we check the redirects, submit the new sitemap and monitor crawling over the following weeks. If the redesign itself is still ahead of you, our website redesign service builds these steps in from the design stage.
How we work
-
01
Access and backup
We ask for an administrator account in our name, hosting access if needed, and we make sure a full backup exists before any work begins. We work on a staging copy, created for the occasion if your host doesn’t provide one.
-
02
Diagnosis
A crawl of the site with Screaming Frog, a review of Search Console, an inventory of the theme and plugins, speed measurements by template. For a broader review, including content and links, a full SEO audit can be done ahead of the engagement.

Optimization of existing pages, new pages according to the plan, then a monthly report on indexing, speed, queries and conversions.
We don’t install any plugin without explaining it, we don’t leave proprietary code that would tie you to us, and updates to WordPress, the theme and plugins stay scheduled with your team.
What drives the cost of WordPress SEO
WordPress SEO is priced by quote. The amount varies with the number of pages and the variety of content, the starting technical state, the theme and builder in use, whether WooCommerce or a multilingual setup is involved, the competition on your target keywords, and how the work is split: we can fix everything ourselves or write precise instructions for your developer.
What to ask a WordPress SEO provider
- Can they read a theme’s code and diagnose a plugin conflict, or do they stop at the SEO plugin’s settings?
- Do they work on a copy of the site and document every change?
- How do they measure speed, and on which pages?
- Are their content recommendations based on keyword research specific to your market?
- Do their reports cover indexed pages, traffic and leads, or just a score?
Be wary of offers that promise rankings within days or suggest installing a miracle plugin: on WordPress as anywhere else, progress comes from a series of verified fixes.
Your questions: WordPress SEO
Can’t find your question? Ask us
Is WordPress good for SEO?
Yes. It produces code Google reads easily, readable URLs and an XML sitemap. Its limits mostly come from overly heavy themes, too many plugins and default settings that let worthless pages get indexed.
Yoast SEO or Rank Math: which should you choose?
Both cover the essentials: titles, descriptions, sitemap, indexing rules and structured data. Rank Math’s free version includes options Yoast reserves for its paid version, such as redirects, while Yoast remains the most widely used and best documented. What matters is keeping only one and configuring it correctly.
Which plugins slow down a WordPress site?
The ones that load their scripts on every page: sliders, forms, chat widgets, social media, duplicate analytics, as well as some page builders. Measuring template by template shows which ones really weigh on your site.
Do you need a WordPress-specialized agency for SEO?
It’s not required, but the provider must understand how the CMS works: archives, permalinks, plugins, template hierarchy. Without that knowledge, technical fixes stay superficial or create new problems.
Does changing themes cause you to lose rankings?
Not necessarily, as long as URLs, titles, content and structured data are kept. The risk comes from reset settings and pages changed without checks: a review before and after the switch prevents it.
How long before the first results?
Indexing and speed fixes often show up in Search Console within a few weeks, once Google’s crawler has come back. Ranking gains tied to content take longer and are measured over several months.
Do you work on WooCommerce stores?
Yes. A WooCommerce store needs specific work on categories, filters, product variations, out-of-stock items and product structured data, on top of the WordPress-specific fixes.
Can you speed up a slow WordPress site?
Yes. We measure Core Web Vitals template by template, then work on caching, images, script loading and pruning the plugins that slow the site down, with a before-and-after report. The rest of the site is left alone, and a full audit can follow if the measurements call for it.
