Non-Breaking Space ( ):
This character prevents line breaks between two words. In SEO, it is useful when you want key phrases (e.g., “cheap flights”) to be treated as a unit in search results and avoid being split across lines in text previews.
Non-Breaking Hyphen (‑):
This character ensures that words connected by a hyphen (e.g., “e-commerce”) do not break into two lines. This is important in SEO, especially for product names and key phrases that need to appear as a whole in search results.
Zero Width Space (​):
An invisible character that allows line breaks at specific positions without adding extra spacing. It’s useful in SEO for improving readability in long titles or meta descriptions.
Narrow Non-Breaking Space ( ):
A narrower version of the non-breaking space. It’s used in cases where you want a smaller but unbreakable space between elements (e.g., between a number and a currency symbol). This character improves the aesthetic display of data.
Hyphen (‐):
A hyphen used to join words. In SEO, it is crucial to use hyphens in URLs instead of underscores because search engines treat hyphens as word separators, which improves the clarity and readability of URLs.
Line Break (
):
This character inserts a line break without starting a new paragraph. While it is not commonly used in SEO, it can be helpful when you need specific content formatting to enhance readability.
Paragraph Separator (
):
This character separates paragraphs. It is particularly useful in advanced content formatting, such as in structured data or JSON-LD, where maintaining the text structure is important for SEO.
Narrow No-Break Space ( ):
A narrow no-break space, mainly used in precise formatting, such as with numbers or currencies. It helps in SEO by ensuring proper display in rich snippets, such as price information.
