What are meta tags and why are they important for SEO?
Meta tags are snippets of HTML code placed in the section of a page that provide information about its content to search engines and social platforms. Although users do not see them directly, they have a huge impact on how the page appears in search results, how its preview looks when shared on social media, and how it is interpreted by crawlers.
The most important SEO element — appears in search results as a clickable headline.
A short description of the page displayed under the title in search results.
Controls the appearance of the page preview when shared on Facebook and LinkedIn.
Analogous to OG — defines the appearance of the link shared on Twitter/X.

Frequently Asked Questions (FAQ)
Not directly — Google has officially confirmed that meta description is not a ranking factor. However, a good description increases CTR (click-through rate), and a higher CTR can indirectly affect position. Furthermore, Google often replaces the description with its own snippet if it deems it a better match for the query.
Google usually displays 120–160 characters of the description, though it depends on the device and result type. On mobile, the limit is lower — approx. 120 characters. A description longer than 160 characters will be truncated with an ellipsis.
Yes — duplicate titles and descriptions are one of the most common SEO mistakes. Google treats pages with identical titles as less valuable. Each subpage should have a unique title describing its specific content.
Open Graph (OG) is a protocol developed by Facebook that controls how a page looks when shared on social media. Without OG tags, social platforms try to pull the title and image themselves, often with poor results. Good OG tags increase CTR when sharing.
A canonical URL informs search engines which version of a page is preferred when the same content is available at several addresses (e.g., with and without www, with and without parameters). Use canonical whenever you have: subpages with sorting/filtering parameters, HTTP and HTTPS versions, or when the same content is available at different URLs.
The noindex directive tells search engines not to index a given page — it will not appear in search results. Use it for: administrative pages, internal search results, pages with UTM parameters, test and staging pages.
