All Green in Yoast, Still Not Found. Why?
5 min read
You installed an SEO plugin, worked every post up to a green light, and three months later nothing finds you. This is one of the most common WordPress questions I get, and the people asking have usually followed a tutorial correctly from beginning to end. The problem is not that they did it wrong. It is that between what those lights measure and whether a search engine can find you sit several layers the plugin never touches. This is about those layers.
1. The lights are the plugin's rules, not Google's
Something most tutorials leave out: Google has no such scoring system. Red, amber and green are a set of writing prompts written by the plugin's authors to stop you skipping the basics, things like whether the title carries the term, whether a description exists, whether the paragraphs run long. Those prompts are useful. What they score is whether a post satisfies the plugin's rules, not whether Google will rank it.
A few of the prompts are simply out of date. How many times a term appears, what density it should reach: that is how relevance was judged more than a decade ago. Search engines now work from what a passage means, and stuffing a term in to hit a ratio reads badly. Reading badly is itself the problem.
2. What the plugin actually reaches is the label layer
Think of a page as a document. The plugin handles its cover and its contents page: the title, the description, what appears when somebody shares it, which pages the sitemap lists, whether a page asks not to be indexed, and the machine-readable block describing what the page is. All of that is real work, tedious by hand, and a plugin does it faster and without forgetting any.
But however good the cover is, the document still has to reach the reader. A search engine has to connect to your server, receive the whole of the content, and not be turned away by a setting somewhere. None of that is within a plugin's reach, because it belongs to the web server and the site's architecture rather than to the post editor.
3. Five things the plugin cannot reach
The table below is how the work actually divides when I take one of these on. On the left is what the owner describes, in the middle whether a plugin can address it, on the right what has to change.
| What you see | Can a plugin fix it | What has to change |
|---|---|---|
| Nothing finds the site, not even the company name | No | Server responses, robots rules, whether the whole site is being turned away |
| The content only appears once the page finishes loading | No | How the site produces its pages, and whether a machine receives a complete document |
| Traffic vanished after a redesign | Mostly no | Redirects from the old addresses. Yoast's free tier has no redirect manager |
| Very slow on a phone | No | How images, fonts and code are loaded |
| Indexed, but sitting far down | No | The content itself, and whether it answers what people are actually asking |
The second row is the one most often misread. Some themes and page builders produce a page as an empty shell that scripts then fill in. A person with a browser sees nothing wrong, but the document a search engine receives first can be empty. The plugin has written a perfectly good title and description into that document. The body simply is not there. In that situation every light is still green.
4. Yoast or Rank Math
This has been compared to death, and the usual conclusion is that Rank Math gives more away in its free tier. That is true: redirect management, several structured data types and keyword tracking all sit behind Yoast's paid tier. If you have not installed anything yet, starting with Rank Math is reasonable.
If you already run Yoast and nothing concrete is wrong, do not switch for the feature list. Switching means migrating the title and description settings on every post, an incomplete migration leaves the two fighting for a while, and what you end up with is the same layer of functionality. Whatever is actually blocking you lives in the right-hand column of that table, and it does not care which plugin you chose.
5. The four checks worth running once it is installed
With the plugin configured and the lights sorted, these four decide whether anybody finds you. None needs code, and half an hour covers all of them.
Half an hour, four checks
- View source and confirm the body text is there. The method from the previous section. This is the most important of the four.
- Open the page indexing report in Search Console. It tells you directly which pages are not indexed and why. That is the only official answer; every other tool is inferring.
- Confirm the sitemap was actually submitted. The plugin generates one, but you have to submit it in Search Console and confirm it reads successfully.
- Check robots.txt is not turning crawlers away. Add /robots.txt to your domain to see it. A block left over from the development phase is a remarkably common accident.
With those done you will know whether the problem is that machines cannot read the site, or that they can read it and it is not good enough. Those are entirely different paths, and most people start rewriting posts before establishing which one they are on. Three months later nothing has moved, which is exactly what you would expect.
6. When it is worth bringing someone in
If all four checks come back clean, your problem is content rather than technology. What follows is sustained writing, on the questions your customers actually ask. There is no shortcut for that and it does not need an engineer.
If view source cannot find your body text, or Search Console names specific pages as excluded, that is technical, and adjusting plugin settings will generally not resolve it. That is worth having someone look at once, because it is a one-off: fixed is fixed, and it does not come back every month.
An SEO plugin is a good thing. It automates a pile of fiddly but necessary label work. Its reach simply ends at that layer, and the reason most sites cannot be found lies below it. Treat the lights as a checklist, spend half an hour on those four checks, and you will know whether to carry on writing or to have someone look at the site itself.
Common questions
- If every Yoast light is green, will my ranking improve?
- Not by itself. The lights are the plugin's own writing prompts and Google has no such score. Being reminded not to skip a title or a description is useful, but prompts about keyword density are out of date, and forcing the ratio makes the writing worse. What decides whether you are found is whether a search engine can read your content in full, and that sits outside the plugin.
- Yoast or Rank Math?
- If nothing is installed yet, starting with Rank Math is reasonable: its free tier includes redirect management and several structured data types that Yoast charges for. If you already run Yoast without a concrete problem, do not switch for the feature list. Migrating settings across every post is not trivial, and you arrive at the same layer of functionality. If you do switch, remove the old plugin completely, because running both emits contradictory markup.
- I installed a plugin and Google still has not indexed my pages. Why?
- A plugin handles titles, descriptions, sitemaps and structured data. It does not control whether a search engine can reach your server, whether the document it receives contains your body text, or whether a robots rule is turning it away. The fastest check is to view the page source and search for a sentence from your article; if it is not there, machines are receiving a version without your content. Then read the page indexing report in Search Console for the official reason.
