What is Meta Description?
The optional summary that can become the result snippet. Absence is not a penalty and Google rewrites most descriptions, so prioritize valuable pages where controlled wording earns clicks.

Title Tag
The clickable headline in search results and the strongest on-page relevance signal. Google rewrites most titles, so clarity and completeness beat rigid length rules.
Click-Through Rate (CTR)
Clicks divided by impressions. Titles, descriptions, brands, and SERP features move CTR at stable positions, which is why snippet work precedes rank-chasing on converting queries.
SERP
The search engine results page: rankings, features, ads, and AI answers competing for the click. Every keyword strategy starts by looking at the SERP it wants to join.
On-Page SEO
Optimizing individual pages: titles, headings, content depth, internal links, images, and schema. On-page work decides relevance once technical SEO has made the page reachable.
H1 Tag
The page’s primary heading naming its topic. Exactly one per page, matching search intent; everything else nests below it in the heading hierarchy.
Heading Hierarchy
The nested H1→H2→H3 outline of a page. A clean hierarchy lets readers scan and lets parsers chunk sections accurately for retrieval and snippets.
