What does this calculator estimate?
A page titled 'Free BMI Calculator' with a 150-character description generates the full title, meta description, robots directive, canonical URL, and Open Graph tags to paste into the page head.
- Meta descriptions should run 150-160 characters for clean search display.
- The canonical URL tells search engines which URL is the original (Wikipedia).
- Open Graph tags control social-share previews on Facebook and LinkedIn.
Why meta tags matter
Meta tags tell search engines and social platforms what a page is about. The title and description appear in search results, and Open Graph tags control how links render when shared on social media — both affect click-through.
Limitations to watch for
Meta tags inform but don't guarantee ranking — Google rewrites titles and descriptions when it chooses. Each page should have unique tags; duplicate metadata weakens pages. OG image paths must be absolute URLs for social platforms.
How to use it in practice
Write a unique title (~60 chars) and description (~150–160 chars) per page, then generate the head block. Set the canonical URL to the page's canonical address. Verify how links render with a social preview tool.
['Enter the title and description.', 'Add optional author, robots, canonical, and OG fields.', 'Copy the generated head block into your page.']
What meta tags are
Meta tags describe a page to search engines and social platforms: the title tag, meta description, and Open Graph tags. The tool generates and previews them from your inputs so the search and share presentation is controlled.
Title tag best practices
Titles should run 50–60 characters, lead with the primary keyword, and include the brand. A title that truncates in search results wastes the most valuable real estate on the page. The tool's character counter enforces the limit.
Meta description best practices
Descriptions of 150–160 characters summarize the page and drive clicks — they are the ad copy of organic search. Including the keyword and a clear value proposition lifts CTR. The tool previews the truncation.
Open Graph and social sharing
OG tags control how links appear when shared: og:title, og:description, and og:image. A missing or wrong OG image makes shares look broken. The tool generates the tags that platforms read.
A worked example
A page targeting 'mortgage calculator' with title 'Mortgage Calculator — Free Payment Estimate | BoringToolsKit' (52 chars) and a 155-character description earns a clean search snippet. The tool returns the exact tags to paste.
How this calculator works
Formula
Generates an HTML head block from inputs: title, meta description, author, language, robots directive, canonical URL, and Open Graph tags (og:title, og:description, og:image, og:type) for social sharing.
Worked example
A page titled 'Free BMI Calculator' with a 150-character description generates the full <title>, <meta name="description">, and OG tags to paste into the page head.
Assumptions to verify
- The user supplies accurate page details.
- OG image URLs are absolute and accessible.
- Tags are placed in the HTML <head>.
Frequently asked questions
What are meta tags?
HTML tags in the page head that describe the page: title, description, robots directives, canonical URL, and Open Graph/social metadata.
What length should a title be?
About 60 characters to avoid truncation in search results. Keep the primary keyword near the front.
What length should a description be?
About 150–160 characters — long enough to summarize, short enough to display fully.
What is Open Graph?
A protocol (og: tags) that controls how links appear when shared on Facebook, LinkedIn, and other platforms.
What is a canonical tag?
The preferred URL for a page — it tells search engines which version to index when duplicates exist.
Do meta tags guarantee rankings?
No — they inform the search engines and shape click-through, but ranking depends on content, relevance, and authority.
Why does Google ignore my title?
Google rewrites titles and descriptions when it decides the page content better represents the query — keep tags accurate and relevant.
How long should a title be?
50–60 characters before truncation in search results.
How long should a description be?
150–160 characters — the click-driving summary in search results.
What are Open Graph tags?
og:title, og:description, and og:image — controlling social share previews.
