What does SiteCheck check?
We audit five foundational on-page SEO factors directly from your page source code:
- Page Title: Verifies whether the <title> tag exists, checks optimal length (30–60 characters), and warns if empty or missing.
- Meta Description: Checks for a compelling meta description tag and verifies it fits search engine snippet guidelines (70–160 characters).
- H1 Heading: Ensures the page contains a prominent <h1> tag communicating your primary topic hierarchy, warning if multiple or missing.
- Image ALT Text: Scans all images for alternative text attributes required for screen reader accessibility and Google Image search.
- Indexability / Robots: Checks meta robots directives and HTTP headers to detect any accidental noindex tags blocking search engines.
On-Page SEO Fundamentals: Technical Guide
A plain-English explanation of core HTML search signals and how they influence crawlers and organic traffic:
Title Tags (<title>)
The <title> tag is the single most influential on-page SEO element. It serves as the primary clickable headline in search engine result pages (SERPs), social media link previews, and browser tabs. Keeping titles between 30 and 60 characters prevents truncation.
Meta Descriptions
The <meta name="description"> tag provides the concise snippet paragraph displayed beneath your page title in search results, directly influencing click-through rates.
H1 Headings
The <h1> element represents the primary headline of your content body. Best practice is to have exactly one descriptive H1 tag per page to establish semantic hierarchy.
Image ALT Text
The alt attribute on <img> tags is vital for web accessibility and image search indexing, allowing screen readers and search engines to interpret image subjects.
Indexability & Robots Directives
Robots directives instruct search engines whether they may index a page and follow its outbound links. An unintended noindex tag can wipe a webpage from Google entirely.
