The SEO title in WordPress lives in the SEO box beneath the post editor: in Yoast SEO it is the “SEO title” field under the SEO tab, and in Rank Math it is the “Title” field under General. It is the text that appears as the clickable headline in Google’s results and in the browser tab, and it is separate from your post title, which is why changing one does not change the other.
If you have never touched that field, your plugin is generating a title from a template, and it is very likely not the one you would have chosen. The rest of this post shows exactly where the field is on each plugin, what to put in it, and why Google sometimes rewrites it anyway.
Three different titles, three different settings. The site title is your website’s name, set under Settings then General. The SEO title is what a plugin sends to the search result, which is what this page covers. What Google displays is a third thing, and Google decides it. See how to change the site title and what to do when Google shows a different title.
What is the difference between the SEO title, the post title and the H1?
This is the question underneath most confusion, and the three are genuinely different things.
| What it is | Where it appears | Set where | |
|---|---|---|---|
| Post title | The name of the post in WordPress | Your blog listing, admin | The title field at the top of the editor |
| H1 | The main heading on the page | Top of the article itself | Usually generated from the post title by your theme |
| SEO title | The <title> tag | Google results, browser tab | Your SEO plugin |
By default most themes and plugins make all three identical, which is fine and often correct. They become different when you want them to be, and that is where the value is.
An example. A post titled “Ten Things We Learned From Rebuilding Our Site” reads well on your blog. As a search result it is invisible, because nobody searches that. Its SEO title could be “WordPress Site Rebuild: 10 Lessons and Costs”, which is what people actually type. The H1 stays friendly, the SEO title does the searching work.
Where is the SEO title in WordPress exactly?
WordPress core does not have an SEO title field. It comes from a plugin. The two common ones:
Yoast SEO
Scroll below the post editor to the Yoast SEO box, open the SEO tab, and the first field is SEO title. Yoast shows a Google preview and a bar that turns orange when you exceed the recommended length.
Rank Math
Open the Rank Math panel on the right, under General, and the field is labelled Title. It shows a similar preview and character counter.
All in One SEO
All in One SEO puts its box below the editor like Yoast rather than in the sidebar like Rank Math. Open the AIOSEO Settings panel, stay on the General tab, and the first field is Post Title. It accepts the same kind of smart tags as the other two, written as #post_title and #separator_sa rather than Yoast’s percent signs, and there is a tag list button beside the field so you do not have to remember them. Site-wide patterns live under AIOSEO, Search Appearance, Content Types.
Site-wide title templates
Site-wide templates are set separately, and they are what fills the title when you leave the per-post field blank. In Yoast: SEO, Search Appearance, where you set patterns like %%title%% %%page%% %%sep%% %%sitename%% for each content type. In Rank Math: Titles & Meta. In All in One SEO: Search Appearance, Content Types. Those templates are what generate your titles when you leave the per-post field blank, and they are worth setting properly because they cover every page you never edit individually.
How long should a WordPress SEO title be?
Around 50 to 60 characters, and Google truncates on pixel width rather than a strict character count.
Two practical points that matter more than the exact number:
Front-load the important words. If it gets cut, the ending disappears. “WordPress SEO Title: What It Is and How to Set It” survives truncation better than “Everything You Need to Know About the WordPress SEO Title Field”.
Your site name is often eating your space. Most default templates append | Your Site Name to every title. On a long brand name that is fifteen or twenty characters gone from every page. Consider removing it from post titles and keeping it only on the homepage.
Why does Google sometimes ignore my SEO title?
Because Google rewrites titles when it decides its own version serves the searcher better, and it has done so routinely since 2021. That is a separate problem from the field being set correctly, and it has a separate answer. If your SEO title is saving fine but the search result shows something else, the causes and the fixes are covered in full in how to change the title Google shows for your WordPress site.
Does the SEO title affect rankings?
Directly, yes, though modestly. Indirectly, it is one of the most valuable fields you control.
The title tag is a genuine ranking signal: it tells search engines what the page is about. But its larger value is click-through. Two results in positions three and four, with the same relevance, will get very different traffic depending on which title reads like it answers the question.
That is why the highest-return SEO work on most established WordPress sites is not new content. It is rewriting titles on pages that already rank on page one but are not being clicked.
How do you write a good one?
A pattern that works across most pages:
Primary keyword + specific detail + what the reader gets
- Weak: “Our Guide to Website Costs”
- Better: “Website Costs: What $1,500 Actually Buys in 2026”
- Weak: “Blog Post About WordPress Speed”
- Better: “Speed Up WordPress: 10 Fixes That Actually Work”
Four rules:
- Keyword near the front, because that is what survives truncation and what the eye scans.
- Be specific. Numbers, versions and concrete outcomes outperform adjectives.
- Write for a human, because a title that reads like a keyword string gets rewritten by Google and skipped by people.
- Make every title unique. Duplicate titles across pages tell Google those pages are interchangeable.
What about the SEO title on other platforms?
The same concept exists everywhere, under different names.
On Squarespace it is the SEO Title, in Page Settings under the SEO tab, with site-wide defaults under Settings → Marketing → SEO Appearance. Same 50 to 60 character guidance, same relationship to the page’s H1. That is covered in how to add keywords to Squarespace.
On Showit, the blog runs on WordPress underneath, so it is Yoast or Rank Math exactly as above.
Can you set an SEO title without a plugin?
Yes, though it is more work than it is worth for most sites.
WordPress core generates the <title> through add_theme_support( 'title-tag' ), and you can filter it with document_title_parts in your child theme’s functions.php. That gives you programmatic control but no per-post interface, so you would be editing code for every title.
The full no-plugin approach, including why the related meta keywords tag is a waste of time entirely, is covered in how to add meta keywords in WordPress without a plugin. Short version: for titles, use the plugin.
Frequently asked questions
Your primary keyword near the front, a specific detail, and a clear indication of what the reader gets, in 50 to 60 characters. Unique on every page.
The <title> tag: the clickable headline in search results and the text in the browser tab. In WordPress it is set by your SEO plugin, separately from your post title.
In the Yoast SEO box below the post editor, under the SEO tab, in the field labelled “SEO title”. Site-wide defaults are under SEO → Search Appearance.
No. The H1 is the heading on the page itself; the SEO title is what appears in search results. They are often identical by default, and making them different is a deliberate optimisation.
Google rewrites titles when it judges its version more useful, usually because yours is too long, too vague, keyword-stuffed, or contradicted by the page’s H1. Making the title accurate and appropriately sized reduces how often this happens.
Not inherently. Titles can be improved at any time, and rewriting underperforming titles is one of the highest-return SEO tasks available. Change one thing at a time so you can measure the effect.
The short version
The SEO title is the <title> tag, set by your SEO plugin, separate from your post title and your H1. Find it in Yoast under the SEO tab or Rank Math under General, with site-wide patterns in Search Appearance or Titles & Meta.
Keep it to 50 to 60 characters, put the keyword near the front, make it specific and unique, and consider dropping your site name from post titles to reclaim the space.
If you have pages ranking on page one that nobody clicks, rewrite those titles first. It is the fastest measurable win in WordPress SEO.
