The website "ultimate-guitar" appears to be a comprehensive resource for guitarists and musicians looking to learn and play songs on the guitar. The screenshot indicates that the site offers a variety of features including:

1. Tabs: A collection of guitar tabs which are a form of musical notation indicating instrument fingering rather than musical pitches. Users can search for tabs by song title or artist.

2. Chords: Similar to tabs, chords are provided for various songs, allowing guitarists to learn the chord progressions necessary to play along with their favorite tracks.

3. Articles: The site likely publishes articles related to guitar playing, music theory, and possibly interviews or features on musicians.

4. Forums: A community feature where users can discuss guitar-related topics, ask for advice, share experiences, and connect with other musicians.

5. Publish tab: An option for users to contribute their own guitar tabs to the site's database.

6. Pro: This seems to be a premium subscription service that offers additional features such as interactive tabs and professional lessons to learn songs easier and faster.

The homepage also showcases a countdown deal for Pro Access at a discounted rate, suggesting promotional offers are available. There are sections for "Shots" which might be user-generated content or quick video lessons/tips
