Indexing
@MartinaKraus11
- understand what the page is about
- textual content, tags, attributes

- prevent indexing with noindex directive
Serving (and ranking)
@MartinaKraus11
- matching search query against the index

Meta-Tags
@MartinaKraus11

@MartinaKraus11
- Always use a different Title for each page
