Free online tools for SEO and web marketing
The sakutto Web Marketing category provides free, no-sign-up tools for SEO, content marketing, and keyword research. Starting with a related-keyword tool powered by Google Suggest, sakutto supports the day-to-day workflow of bloggers, SEO specialists, and content marketers.
Discover user intent with related keywords
related-keywords pulls related search terms from Google Suggest in one click. Type a query and you get a list of the words and phrases people actually search for — perfect for content planning and SEO article outlines.
Plan SEO content for blogs and owned media
Use it for ideation, search-intent mapping, long-tail keyword discovery, and as a starting point for competitor research. It's a free entry point that complements paid SEO platforms (Ahrefs, Semrush, etc.) for individual bloggers and content teams alike.
More marketing tools coming soon
Today the lineup centers on related-keyword research, but more SEO and content-marketing tools are on the roadmap: suggest analysis, rank tracking, SEO title length checks, OGP previews, and structured-data validators.
How to use the related-keywords tool
Pull related keywords from Google Suggest and feed them into your SEO planning. The whole flow takes three steps.
Type the seed keyword you want to research
Open related-keywords and enter the keyword you want to explore — for example, "markdown", "PDF compress", or "SEO". Single words and phrases both work, and the tool fetches results from Google Suggest in real time.
Review the related keyword list
The tool shows the suggestions branched by a–z and other initial-character splits. You instantly see high-volume terms, long-tail variants, and the specific phrases users actually search for.
Copy or download for SEO planning
Copy the results into a spreadsheet or download them as CSV. Use them as the source data for SEO article outlines, content maps, and internal-link planning.
related-keywords involves external API communication
Unlike file-based tools, related-keywords needs to call the Google Suggest API, so external communication is involved. Here's exactly what gets transmitted and how it stays safe.
- Suggest API is fetched via Cloudflare Workers
- Because of CORS constraints, related-keywords calls the Google Suggest API through a Cloudflare Workers proxy. Only the search keyword you typed is sent to the API — no other user data, files, or browsing history.
- Only the keyword is sent and nothing is stored
- The data sent over the wire is the search keyword (query string) only, with no link to user accounts or personal information. The Cloudflare Workers proxy does not persist your queries or results — only short-lived edge cache exists. See our privacy policy for details.
