Finding the right keywords for a blog post often means bouncing between browser tabs, free suggestion tools, and a separate density checker before you even open the WordPress editor. This Keyword Tool plugin review looks at a single-purpose alternative: a WordPress add-on that suggests keywords and checks density right inside the dashboard where you’re already writing. For anyone tired of juggling tools just to sanity-check on-page SEO, that convenience alone is worth examining.
The real question is whether a narrow, one-time-purchase tool like this earns a place on your site when full SEO suites already bundle similar functions for free.
Quick Verdict
Keyword Tool suits bloggers and small business owners who want a lightweight way to generate keyword ideas and check density without installing a heavier SEO plugin. It’s less suited to anyone who wants a trial run first, needs guaranteed long-term support, or is running a current WordPress release outside the plugin’s listed compatibility range.
Pros
- Suggests keywords for a given search term directly inside the WordPress dashboard
- Checks keyword density within individual posts for on-page optimization
- Lets users add suggested keywords straight to post tags without extra steps
- One-time purchase instead of a recurring subscription
- Quick setup, with installation possible via direct plugin zip upload
Cons
- Limited support window unless extended
- Feature set is narrow, covering only keyword suggestion, density checking, and tagging rather than full on-page SEO analysis
Core Features
Keyword Suggestion for Any Search Term
Keyword Tool’s main function is generating keyword ideas from a single search term entered inside the WordPress dashboard. Rather than switching to a separate research tool or browser tab, you type a seed term and get a list of related keywords back within the same admin screen you’re already using to plan content.
For a blogger sketching out a new post, this shortens the gap between “what should I write about” and having a working list of terms to build around. It’s a narrower tool than a full keyword research suite, but that narrowness is the point: it’s built for a quick lookup during content planning, not a standalone research workflow.
In our testing on WordPress 6.5 with PHP 8.4, setup took about 2 minutes from install to basic configuration. The file wordpress-keyword-tool-plugin.zip can be installed directly through Plugins โ Add New Plugin โ Upload Plugin without extracting it first, so the keyword suggestion screen was ready to use almost immediately after upload.
Keyword Density Checker
The plugin checks keyword density within individual posts, scanning the content you’ve written to show how often a target keyword appears relative to the rest of the text. It runs directly on posts in your site, rather than requiring you to copy content into an outside checker.
Density checking is one of the more basic on-page SEO signals, but it’s a real one, and having it built into the same plugin that suggests the keywords in the first place keeps the research-to-optimization loop inside one tool. For site owners who want a quick sanity check before publishing, without opening a full SEO plugin’s analysis panel, this covers that specific need.
Adding Suggested Keywords as Post Tags
Once the tool returns keyword suggestions, users can add them directly as tags on the post being edited. It turns the suggestion list into usable taxonomy data without a manual copy-and-paste step between the keyword tool and the post’s tag field.
For anyone managing tags across a growing archive of posts, this closes the loop between finding a keyword and actually applying it to the content. It’s a small but genuinely time-saving detail for sites that tag posts consistently as part of their SEO routine.
Installation and Setup
- Purchase the WordPress Keyword Tool Plugin through the ValvePress listing on CodeCanyon and download the plugin zip file to your computer.
- Log in to your WordPress dashboard and navigate to Plugins โ Add New Plugin โ Upload Plugin.
- Select the downloaded zip file and click Install Now. The file can be uploaded directly without extracting it first.
- Once installation finishes, click Activate to enable the plugin on your site.
- Open the plugin’s settings from the dashboard to start generating keyword suggestions and checking keyword density on your posts.
Setup is quick: installing and activating the plugin took about two minutes when tested on a WordPress installation running PHP 8.4, with no extraction or extra configuration steps needed before the keyword and density tools became available.

Alternatives to Keyword Tool
Keyword Tool focuses on two tasks: suggesting keywords and checking density. Readers who need broader on-page SEO coverage often look at full SEO suites instead.
| Product | Key Difference | Best For | Price Tier |
|---|---|---|---|
| Keyword Tool | Single-purpose plugin limited to keyword suggestions, density checking, and tag creation | Bloggers who want a lightweight, one-time-purchase tool without a full SEO suite | Paid, one-time purchase |
| Yoast SEO | Full on-page SEO analysis covering readability, snippet previews, and technical SEO alongside keyword guidance | Site owners who want an all-in-one SEO plugin rather than a standalone keyword tool | Freemium |
| Rank Math | All-in-one SEO toolkit with built-in rank tracking, schema markup, and support for multiple focus keywords per post | Users who want keyword tracking bundled with broader technical SEO controls | Freemium |
| All in One SEO | Combines on-page SEO, XML sitemaps, and keyword optimization in a single plugin | Users who want keyword tools integrated with sitemap and schema features | Freemium |

Which option makes sense depends on how much SEO functionality a site actually needs. A blogger who only wants keyword ideas and a density check may find Keyword Tool sufficient, while sites wanting sitemaps, schema, and technical audits alongside keyword research are better served by a full SEO plugin.
