How to Use SEO Cheki: Features, Limits, and Search Console Checks

May 25, 2026

Author: Shusaku Yosa

SEO Cheki is a Japanese free tool for checking basic information about public web pages and selected search rankings. It can support an initial inspection of titles, descriptions and headings. It does not provide a complete Google quality score or a guaranteed route to higher rankings.

Choose a public URL and a specific question. Do not submit private administration URLs or URLs containing personal information or access tokens to an external diagnostic service.

A simple workflow

Open the official SEO Cheki page.
Enter the public URL and inspect the available site information.
Compare the reported elements with the page itself.
If checking rankings, enter the query and read the displayed coverage limits.
Record the date, URL, conditions, observation and next investigation.

On October 1, 2026, the official screen stated that Google and Yahoo! rankings were checked through position 10. Do not interpret its result as a top-100 check. Follow the current interface if limits change.

Interpret observations rather than chase numbers

Element	Useful question	What it cannot prove
Title	Does it identify the actual topic and audience?	An ideal length does not guarantee ranking
Description	Does it accurately summarize the page?	Google may show different snippet text
Headings	Is the information organized clearly?	Repetition is not evidence of relevance
Outgoing links	Are references and next steps useful?	More or fewer is not inherently better
Load time	Is there an unusual observation?	Not equivalent to field Core Web Vitals
Rank result	What was observed within the checked range?	Absence does not prove non-indexing

For example, an abstract title may need to specify whether the article explains setup, pricing or comparison. Adding “ultimate guide” without changing the answer is less useful. This is an editorial improvement, not a ranking promise.

Avoid density targets and misleading index counts

Word-frequency observations can reveal awkward repetition. They do not justify a universal keyword-density target such as 3–5%. Use the terminology necessary to answer the question, including relevant conditions and examples.

Similarly, a site: search count is not an exact inventory of indexed pages. For a site you manage, inspect indexing information in Search Console. A tool’s inability to retrieve a page may involve JavaScript, access conditions or the diagnostic tool itself; it is not automatically proof of a site outage.

Assign each tool a role

Question	Evidence source	Important limitation
Basic public-page elements	SEO Cheki and the page	Retrieval may differ from rendering
Google visibility and clicks	Search Console	Query anonymization and aggregation
Individual indexing status	URL Inspection	A time-specific observation
Behavior after arrival	GA4	Depends on valid collection and definitions
Performance diagnosis	PageSpeed Insights	Separate field and laboratory data

A single ranking check is not the same as Search Console’s average position over a period. Document country, device, timing and query conditions. Competitor public-page information does not reveal their private conversion rate, revenue or complete traffic history.

Keep a before-and-after record

Before rewriting, record the mismatch you observed and supporting evidence. On the edit date, document the intended change. Later, compare search performance and on-site behavior separately under consistent conditions.

A useful worksheet contains: URL; date; observation; hypothesis; proposed edit; owner; verification; follow-up period. With few impressions, one click can create a large percentage change, so preserve counts and query context.

Respect the service’s usage limits rather than switching IP addresses to bypass them. If the investigation needs larger coverage, choose a service designed for that volume. SEO Cheki is most useful as a starting observation that leads to a better question and a verifiable change.
