Free Online SEO Tools for Search Engine Optimisation

SEO involves many different areas of website optimisation, from researching keywords and creating useful content to improving technical website signals, internal links, structured data and search result presentation. YesTools brings these tasks together in one collection of free online SEO tools.

Whether you are researching a new topic, reviewing an existing page, planning a content strategy or checking technical SEO elements, the directory provides tools for a wide range of common search engine optimisation tasks.

Keyword Research and Search Intent

Keyword research helps identify the terms and questions people may use when searching for information, products or services. The keyword tools in this collection cover keyword generation, long-tail keywords, related terms, clustering, grouping, permutations, density and search intent. These tools can help organise keyword research before content and optimisation work begins.

On-Page and Content SEO

On-page SEO includes elements such as page titles, meta descriptions, headings, URLs, keyword placement, internal links and image alternative text. Content SEO also considers topics, structure, readability, questions, content gaps and related articles. The tools in these sections can help with both planning and reviewing these elements.

Technical SEO and Structured Data

Technical SEO covers the parts of a website that affect crawling, indexing and how pages are presented to search engines. Tools for robots.txt, XML sitemaps, canonical URLs, redirects, hreflang, indexability and crawlability can assist with technical checks. Structured data and JSON-LD tools provide additional resources for generating and reviewing schema markup.

Links, Local SEO and E-commerce

Internal linking and backlinks are important areas of SEO planning and analysis. The directory includes tools for internal link structures, orphan pages, anchor text, backlink analysis, broken links and link-building ideas. Separate local SEO and e-commerce SEO sections cover location-based optimisation, business information, product pages, category pages and related SEO requirements.

SEO Audits, Performance and Calculators

SEO auditing tools can help review individual areas of a website or provide broader checks across technical, content, metadata, links, schema and other SEO factors. Performance tools cover page size, loading metrics and Core Web Vitals, while SEO calculators can be used for estimating traffic, CTR, conversions, revenue, investment and other numerical measures.

Using the SEO Tools on YesTools

Each SEO tool has its own dedicated page with an interface designed for the specific task. Select the relevant tool from the directory above, follow the instructions provided on its page and enter the information required by that tool.

Depending on the tool, you may be able to generate, check, compare, calculate, analyse or preview SEO-related information. Results should be reviewed in context and checked against your website, content and SEO objectives before being used in production.

SEO recommendations and calculated estimates can depend on the inputs provided and the assumptions used by an individual tool. No single metric or automated check should be treated as a complete assessment of search performance.
