How to Use the SEO Score Checker

Search Engine Optimization (SEO) is the art and science of ranking higher in search engines like Google and Bing. While there are over 200 ranking factors, on-page technical SEO provides the foundation. This tool scans your raw HTML to verify that your page is built in a way that search engine bots can understand.

Step-by-Step Guide

Get Source Code: Go to the webpage you want to analyze. Right-click anywhere on the page and select "View Page Source" (or press Ctrl+U).
Copy HTML: Select all text (Ctrl+A) and copy it (Ctrl+C).
Paste & Analyze: Paste the code into the text box above and click "Check SEO Score".
Review: The tool will parse your HTML and provide a score from 0 to 100 based on critical ranking factors.

What Does This Tool Analyze?

Title Tag: Checks if a title exists and if it falls within the optimal length (50-60 characters) to avoid truncation in search results.
Meta Description: Verifies the presence and length of the meta description, which influences click-through rates.
H1 Heading: Ensures there is exactly one H1 tag per page to clearly define the main topic to search bots.
Image Alt Text: Scans images to ensure they have descriptive alt attributes for accessibility and image search ranking.
Link Structure: Counts internal vs. external links to ensure your page is well-connected.

Pro Tip: A perfect score of 100 doesn't guarantee a #1 ranking, but it does mean your page is technically sound. Content quality and backlinks are the other two pillars of SEO success.

Common SEO Mistakes to Avoid

Missing Meta Descriptions: Without a meta description, Google will pick random text from your page to display in search results, which might not be compelling to users.

Multiple H1 Tags: While HTML5 technically allows multiple H1s, it is best practice to have a single, powerful H1 that contains your primary keyword.

Broken or Empty Alt Tags: Accessibility is a ranking factor. Ensure every image has an alt attribute that describes the image contents to screen readers.
