What is meta tags?
Meta tags are snippets of HTML in a page's head section that describe the page to search engines, social platforms, and browsers rather than to the person reading it.

Technical definition
Meta tags are HTML elements placed in the document head that provide metadata about a page. The ones that matter in current practice:
- Title tag: the page's name in search results and browser tabs. A ranking factor and the strongest click signal. Aim for 50 to 60 characters.
- Meta description: the summary shown beneath the title in results. Not a ranking factor, but it drives click-through. Aim for 140 to 160 characters.
- Canonical tag: declares the preferred URL when a page is reachable at more than one address.
- Robots tag: controls whether a page is indexed and its links followed.
- Viewport tag: tells mobile browsers how to scale the page. Required for responsive rendering.
- Open Graph and Twitter Card tags: control the title, description, and image when a link is shared.
The meta keywords tag has no effect on any major search engine and has not for well over a decade.
In plain terms
Meta tags are the label on the outside of your page. Visitors do not see them on the page. Search engines and social platforms read them to decide what your page is and how to present it.
Why it matters
The title tag and meta description are your advertisement in search results, and most small business sites either leave them empty or let a platform fill them with the business name on every page.
Both cost you clicks. Ten results compete on that page, and yours is described by whatever text was available. Writing a specific title and description for each page is the cheapest ranking-adjacent work there is: no design, no code, minutes per page.
The Open Graph tags matter for a different reason. Without them, a link to your site shared on social platforms shows no image and a truncated title, which reads as broken.
