Search algorithms evolve continuously, but core ranking fundamentals remain anchored in technical health, content clarity, mobile speed, and user experience. Use this quick checklist to understand the signals our free SEO audit tool and website analyzer inspects:
Your title tag is the single strongest on-page ranking signal. Keep it between 50–60 characters, front-load your primary keyword, and make it compelling for human searchers.
While not a direct ranking factor, persuasive meta descriptions between 140–160 characters drastically boost organic click-through rates (CTR) in Google SERPs.
Prevent duplicate content penalties and index dilution by ensuring every page declares a self-referencing or authoritative rel="canonical" tag.
Every page requires a single, descriptive H1 tag followed by logical H2 and H3 subheadings matching search intent and natural question phrases.
As search shifts to Google AI Overviews and ChatGPT Search, your content must feature concise answer passages, JSON-LD Schema, and clear factual entity definitions.
Fast load times, responsive interaction (INP), and visual layout stability (CLS) are mandatory Google ranking signals for both mobile and desktop.
Our SEO score checker grades your website health on a 0–100 scale combining on-page tags, technical infrastructure, mobile readiness, and security:
