Open toolWhy use these SEO tools?
Every page on the open web competes for attention. The SEO Smart Engine tools suite is built to remove the guesswork: each utility addresses one of the highest-leverage levers in modern search — technical SEO, structured data, indexability, on-page optimization, and SERP click-through.
Whether you run a small business website, manage an agency portfolio, or maintain a creator brand, the same fundamentals apply. Clean indexable URLs, accurate titles and descriptions, valid schema markup, and a tidy sitemap and robots.txt remain the foundation that AI-powered recommendations are built on top of.
Best free SEO audit tool in 2026
The SEO Smart Engine free SEO audit crawls your site, scores it against Google Search Essentials, checks Core Web Vitals (LCP, INP, CLS), validates schema, and flags every "discovered currently not indexed" or soft 404 page. You get a prioritized AI action plan instead of a 400-row CSV — the difference between knowing what's wrong and knowing what to ship next. Want a deeper walkthrough?

IndexNow vs Google Indexing API
IndexNow is the open protocol used by Bing, Yandex, Naver — and now signaled to Google — for instant URL submission. The Google Indexing API is limited to JobPosting and BroadcastEvent schema. For everything else, IndexNow is the fastest way to push new and updated URLs to search engines. Use our index status checker to confirm a page is indexable, then read the indexing problems guide for crawl-budget optimization tips.
Schema markup generator for FAQ, Product, and LocalBusiness
Structured data is how Google and AI search engines understand your page. The schema markup generator builds valid JSON-LD for Article, Product, FAQ, HowTo, LocalBusiness, Organization, and Breadcrumb — the schemas that unlock rich results in Google Search and citations in Google AI Overviews, ChatGPT search, and Perplexity. Pair it with our FAQ schema guide to qualify for FAQ rich snippets.
