Free Keyword Research Tool: Bulk Related Keywords

A keyword research tool earns its place when one starting phrase returns enough ideas to plan a page, because checking phrases one at a time is slow and easy to cut short. The free sakuttoAI related keywords tool takes a single seed keyword, meaning the word or phrase you start from, and returns Google's autocomplete suggestions for it in one run.

Related keywords vs. keyword suggest: the difference

Keyword suggest means the autocomplete predictions Google shows while you type, and related keywords are the extra searches listed near the bottom of a results page; the sakuttoAI tool collects the suggest kind. The two lists answer different questions.

Suggest shows how people finish a phrase, so it points at what to write about. Related searches show neighboring topics, so they point at what else a page may need to cover.

Guides such as the Mangools beginner's guide to keyword research treat the two as separate sources of ideas: Google suggestions (autocomplete) in one place, and "Searches related to..." in another. Collecting both gives you the phrases to target and the topics to cover.

For a page you are about to write, run the tool for the suggest list. Then open the Google results for the same phrase and note the related searches by hand. Two short lists side by side are enough to start an outline.

Find related keywords in bulk with a free tool

Three steps produce a bulk list: enter a seed keyword, filter the ideas by search intent, and export them. The tool's name uses "related keywords" loosely: what it returns is the suggest list described above.

The tool requires sign-in, but a free account works, and you sign in by email link or Google with no password. Free accounts get 30 searches per day, and the Pro plan has no daily limit.

Thirty searches a day is enough for one seed keyword on each of 30 pages. Anyone planning a larger site in one sitting will hit that limit and should look at Pro.

Step 1: enter a seed keyword and run the search

Type one seed keyword into the tool and run the search; it fetches Google's suggest keywords for that term in bulk. A seed keyword is the starting phrase everything else grows from. Pick one that names the topic of the page you plan to write, not the whole industry.

For a page about email newsletters, "email newsletter" is a better seed than "marketing". The narrower seed keeps the suggestions on one topic, so the list is easier to sort later.

Step 2: filter ideas by search intent

Keep the suggested phrases that match what your page's reader wants to do, and drop the rest. Search intent is the goal behind a query. The Mangools guide scores each keyword on popularity, keyword difficulty, and relevance, which it describes as search intent, so intent sits alongside the numbers rather than after them.

Intent splits phrases that look alike. A reader who types "keyword research tool free" wants a tool to open, while a reader who types "what is keyword research" wants an explanation. One page rarely serves both, so mark each phrase with its goal and keep the group that fits your page.

Step 3: export keyword ideas to CSV or Google Sheets

Export the kept phrases to the clipboard, a CSV file, or Google Sheets, depending on where you will work with them. The table below pairs each option with the job it suits.

The export holds the phrases only. It carries no search volume figures, so add those from a separate source if you need them.

What to look for in a keyword research tool for SEO: four checks

Judge a keyword research tool on four points: what it returns for each search, which export formats it offers, whether it needs an account, and how many searches it allows per day. Roundups such as Zapier's guide to free keyword research tools and Neal Schaffer's comparison of free and paid tools return to the same split: free tools limit volume or features, paid tools lift those limits. The sakuttoAI tool's own answers, stated plainly, are below.

The account requirement is a real cost for someone who wants a one-off lookup with no sign-in. It pays off for repeat work, since the same free account covers every later search up to the daily limit.

Free keyword research tool or Google Keyword Planner?

Use a free suggest tool when you need many phrases for one page, and use Google Keyword Planner when you need search volume figures. SEO.com's roundup of keyword research tools names Google Keyword Planner and labels it best for finding related keywords.

The tools differ in what they hand back. This tool returns phrases and exports them, while the planner reports figures inside Google's advertising screens. The sakuttoAI tool does not output search volume, so the two do not replace each other.

Take a writer who is preparing one new article and needs phrases for headings. That writer should run the free tool, export to Google Sheets, and sort by intent.

Someone comparing two topics by demand needs volume, and should read it from the planner or another source. Backlinko's free keyword tool compares how accurate different tools' search volume data are, so use volume as a rough guide, not an exact count.

Turn keyword ideas into headings and long-tail topics

Each phrase in your list is a candidate heading; give the main headings different phrases from the same group. A main heading (H2) and the sub-heading (H3) beneath it should not repeat each other. If the group holds "free keyword research tool" and "keyword ideas generator", put one in the H2 and the other in an H3.

A long-tail keyword is a longer, more specific phrase, and it is a good source of sub-headings. Backlinko recommends long-tail keywords in its keyword tool guide; a narrow phrase also tells you what the reader is trying to do.

Suppose your group has the broad phrase "email newsletter" and the longer one "email newsletter subject line ideas". The broad phrase becomes the H2, and the long one becomes a small section under it.

Read the finished heading list top to bottom before you draft. A heading that sounds unnatural when read alone can mean the phrase was pasted in unchanged. Reword it into the wording a person would say.

Keyword grouping: one search intent per page

Group phrases that share one search intent, and assign each group to exactly one page. Two pages that chase the same intent compete with each other, while one page with mixed intents answers neither well.

WordStream's keyword research walkthrough puts this in a 10-step process: step 1 is understanding keyword intent, and step 9 is grouping your keywords. Grouping is easiest once the list is complete.

In Google Sheets, work through the list in this order. Four steps take the list from a raw column to one block per page.

• Paste the exported phrases into one column.
• Add a column that names the goal behind each phrase, such as learning, comparing tools, or picking a tool to open.
• Sort by that column so phrases with the same goal sit together.
• Give each block a page, and use the block's phrases for that page's headings.

Phrases that fit no block either belong on a new page or on none. Dropping them is fine, because a list is a pool to choose from, not a checklist to cover.

From one seed keyword to a page's headings

The shortest route is to sign in for free, pull suggested phrases in bulk from one seed keyword, group them by search intent, and give each group to a single page. The free sakuttoAI keyword research tool exports to the clipboard, CSV, and Google Sheets, with 30 searches per day on a free account and no daily limit on Pro. Its output is phrases only; use Google Keyword Planner or another source for search volume.

Start with the page you are writing next. Run one seed keyword, sort the phrases by intent, and use the first group as that page's headings.
