# Key concepts

{% columns %}
{% column width="25%" %}
**GEO**
{% endcolumn %}

{% column width="75%" %}
**Generative Engine Optimization**

Getting your brand cited and recommended by LLMs like ChatGPT, Perplexity, and Gemini. Different from SEO, good search rankings don't automatically translate to AI recommendations. Scribble is built specifically for this.
{% endcolumn %}
{% endcolumns %}

{% columns %}
{% column width="25%" %}
**UGC**
{% endcolumn %}

{% column width="75%" %}
**User-Generated Content**

Real content created by real people, not brands, agencies, or AI tools. LLMs weight UGC highly because it reads as authentic, independent signal. All Scribble campaigns produce human-written UGC by policy.
{% endcolumn %}
{% endcolumns %}

{% columns %}
{% column width="25%" %}
**Citation**
{% endcolumn %}

{% column width="75%" %}
**Citation**

When an LLM directly links to or credits a piece of content as a source in its answer. The highest-value signal on the ScribbleAI dashboard, it means the model trusts your content enough to surface it as evidence.
{% endcolumn %}
{% endcolumns %}

{% columns %}
{% column width="25%" %}
**Mention**
{% endcolumn %}

{% column width="75%" %}
**Mention**

When an LLM references your brand by name in an answer without linking to a source. Valuable brand presence, but a step below a citation. Both are tracked separately on the ScribbleAI dashboard.
{% endcolumn %}
{% endcolumns %}

{% columns %}
{% column width="25%" %}
**SoV**
{% endcolumn %}

{% column width="75%" %}
**Share of Voice**

The percentage of tracked queries where your brand appears in LLM responses, compared to competitors. This is the core metric Scribble helps you grow, and the number you watch move in the ScribbleAI dashboard.
{% endcolumn %}
{% endcolumns %}

{% columns %}
{% column width="25%" %}
**Bounty**
{% endcolumn %}

{% column width="75%" %}
**Bounty**

A brand campaign on Scribble. Brands post a brief with a reward pool in USDC. Creators discover it on the bounties marketplace, submit content, and earn rewards for approved submissions.
{% endcolumn %}
{% endcolumns %}

{% columns %}
{% column width="25%" %}
**Brief**
{% endcolumn %}

{% column width="75%" %}
**Creator Brief**

The campaign document creators receive when they enter a bounty. Covers the project background, approved content categories, platform guidelines, topics to cover, and reward structure.
{% endcolumn %}
{% endcolumns %}

{% columns %}
{% column width="25%" %}
**CRS**
{% endcolumn %}

{% column width="75%" %}
**Citation Readiness Score**

A ScribbleAI metric showing how well-positioned your brand is to be cited by LLMs, benchmarked against competitors in your category. The score factors in domain authority, indexed content volume, and multi-platform presence.
{% endcolumn %}
{% endcolumns %}

{% columns %}
{% column width="25%" %}
**GAP**
{% endcolumn %}

{% column width="75%" %}
**GEO content gap**

A query or keyword where a competitor appears in LLM answers and you don't. Scribble identifies these automatically in your dashboard. Every gap is a campaign brief waiting to happen.
{% endcolumn %}
{% endcolumns %}
