2026 Google SEO Beginner's Guide - Free Page Inspection Tools

As SEO rules and algorithms for business websites continue to improve, the scope of improvement extends beyond just deeper analysis to include broader coverage. As the boundaries of content covered by these algorithms are constantly expanded, the professional knowledge and tools required for operating a business website are also increasing.

In practical applications across different projects, the focus of business website SEO optimization will vary depending on the industry and the stage of the business website's development. The biggest cost of business website SEO is determined by the rules of the game in search engines: either spend time on SEO or spend money on SEM. Of course, both of these require businesses to find professional operators who can make the time-to-result conversion rate of SEO higher and make the money spent on SEM more worthwhile, achieving tangible results.

Below is a summary and core function description of the commonly used SEO tools on this page, which will help you improve the convenience and efficiency of your work and have more time planning strategies during the application process.

They also ensure visitors always access the correct page, avoiding duplicate content and thus improving user experience.

Siteliner's "Site Overview" feature, corresponding to the Site Results section in its report, is essentially an overview panel of the entire website scan results. It first crawls your site's pages and then summarizes site-wide quality issues to help you quickly identify SEO and content structure problems.

The overview mainly includes 5 categories of information:

Your Pages: Lists pages that have been successfully scanned, displaying their URL, title, Page Power, page size, word count, modification date, etc. Page Power reflects the degree to which a page is linked from important pages within the site; the higher the value, the more "important" it is in the site's internal structure.

Duplicate Content: Identifies duplicate content within the site, showing how much content from each page also appears on other pages, and allows for further highlighting of duplicate paragraphs. Siteliner will separately identify recurring "Common Content" such as menus, headers, and footers to avoid misidentification.

Broken Links: Checks for broken links within the site, indicating which pages contain broken links, making it easier to fix user experience and search engine crawling issues.

Skipped Pages: This section tells you which pages were skipped and why, such as canonical, robots.txt , noindex, nofollow, redirection, or server error. This section is useful for troubleshooting "why some pages were not indexed/scanned".

Related Domains: Displays subdomains or similar domains related to the site you entered, helping you determine if you need to include other subdomains in the scan.
