How long should a title tag be?

Around 50 to 60 characters, though the real limit is pixel width rather than character count. Lead with the distinguishing term — if it is truncated, the end is what gets cut, so anything essential belongs at the front.

Does the meta description affect rankings?

Not directly. It affects click-through rate, which affects how much traffic a given ranking produces. Search engines frequently rewrite descriptions to match the query, but a good one is used often enough to be worth writing.

Is there a free meta tag checker?

Yes. Ours is free and needs no account for your first scan. It checks titles, descriptions, canonicals, viewport and robots directives, and reads them from the rendered page so client-side tags are included.

Free meta tag checker: the tags that build your search result

Titles and descriptions are what a result is assembled from, and duplicates across templated pages are the most common serious on-page problem there is.

By Sapun Lamichhane · Arcetis

Meta tags are among the oldest parts of SEO and still among the most frequently wrong, because they are usually generated by a template and templates do not notice when they produce the same output for a thousand pages.

The title tag

The strongest on-page signal you control and the largest text in the result. Around 50 to 60 characters, unique per page, leading with the term that distinguishes this page from the others on your site.

Front-loading matters because truncation happens at the end. "Blue Widgets | Acme" survives being cut; "Acme — the UK's leading supplier of, among other things, blue widgets" does not.

The meta description

Not a ranking factor, and worth writing anyway. It is the sentence that persuades someone to click rather than scroll past, and around 150 characters is what survives display.

Search engines often rewrite it to match the query. That is not a reason to skip it — it is a reason to write one good enough to be used when the query matches your page's actual subject.

The canonical

Declares which URL is the real one. Without it, tracking parameters, session ids and trailing-slash variants can each be treated as separate pages competing with each other. Every indexable page should carry a self-referencing canonical.

The viewport

One line, and without it a mobile browser renders your page at desktop width and zooms out. Since indexing is mobile-first, that unusable version is the one being assessed.

The robots meta tag

The one worth checking every time you deploy. A noindex left over from staging is the single most expensive line a site can ship by accident, and it produces no error — traffic simply falls away over the following weeks.

Why duplicates are the real problem

A missing description is a mild loss. Fifty identical ones across a product template is a site whose pages compete with each other for the same query, and none of them wins outright. This is the most common serious finding on templated sites and the one most worth automating properly.

What free means here

Our meta tag checker is free, with no account needed for your first scan. It reads from the rendered page, so tags your framework sets client-side are included — a checker reading only the raw response would report them as missing.
