Preferences control the look, voice, and rules that theStacc applies to every blog it writes for a project. Set them once and the AI follows them on every post. Find them under Content SEO > Settings > Preferences. The page has three tabs: Writing, Images, and Content. Changes save automatically the moment you pick an option or toggle a switch — there is no separate “Save” button on the style choices.
Preferences are per project. If you run more than one website, switch projects first (top-left project picker), then set preferences for the one you want. Only project editors can change these settings; viewers see them but can’t edit.

​
Writing tab: writing style and tone

Pick the voice the AI writes in. There are 12 styles, and the choice applies consistently across every blog in the project:
  • Informative — fact-driven, educational content
  • Simple & Clear — easy to read, jargon-free
  • Formal — polished, corporate tone
  • Casual — relaxed, everyday language
  • Enthusiastic — energetic and excited
  • Persuasive — convincing, action-oriented
  • Professional — business-appropriate, trustworthy (default)
  • Friendly — warm, approachable tone
  • Entertaining — fun, engaging to read
  • Inspirational — motivating and uplifting
  • Analytical — data-driven, logical approach
  • Narrative — story-driven, immersive
New projects start on Professional. Click any tile to switch; the selected style shows a checkmark. If you’d rather not pick a label, theStacc can learn your voice from real examples instead. Add a few of your own published articles as example articles (under Content SEO > Settings > Content Details) and the AI matches their tone for more consistent branding. See Sources & Brand Voice for how that works.

​
Images tab: image style

Choose the visual style for the AI-generated images in your posts. This style applies to every image in every article. There are 6 options:
  • Photorealistic — natural photography look (default)
  • Flat Illustration — clean 2D vector style
  • Cinematic — dramatic, movie-like feel
  • Watercolor — soft, painterly textures
  • Sketch — hand-drawn line art
  • Brand & Text — photo with a branded text overlay
New projects start on Photorealistic. Each option shows a live preview thumbnail so you can see the look before you commit.

​
Content tab: what goes inside each post

The Content tab is where you turn whole features on or off and add the links, videos, and rules the AI should follow.

​
Content options (toggles)

Four switches decide what types of content the AI is allowed to add. Their defaults are:
  • Include YouTube Videos — embed relevant YouTube videos in posts. (On by default)
  • Include CTAs — add call-to-action sections in content. (On by default)
  • Include Internal Links — link to other pages on your website. (On by default)
  • Include Competitor Links — link to competitor sites when they’re mentioned in content. (Off by default)
Each toggle also acts as a show/hide control. When a toggle is on, its configuration section appears lower on the tab; when you turn it off, that section is hidden (and the AI stops using it). So if you don’t see the CTA, internal-links, or YouTube section, check that the matching toggle is on.

​
YouTube channel

Visible when Include YouTube Videos is on. Add your YouTube channel URL and the blog generator will find and embed relevant videos from your channel inside your posts. The URL must start with http:// or https:// (for example, https://youtube.com/@yourchannel). If you paste something without one of those, theStacc asks you to fix it before saving. Visible when Include CTAs is on. These are the links you want woven into your blog posts — the AI places them naturally in the content rather than dropping a generic button at the end. Add as many as you need. Each CTA link has:
  • Label (required) — the clickable text, e.g. “Get Started Free”
  • URL (required) — where the link points
  • Type — Primary, Secondary, Social, or YouTube. This is a tag that helps you organize links (for example, your main offer vs. a supporting one); it’s shown as a colored badge on each link.
  • Notes (optional) — a hint for the AI, e.g. “Use in conclusion”
Allowed link addresses. A CTA URL must start with one of these:
  • http:// or https:// — a full web address (https://yoursite.com/signup)
  • mailto: — an email link (mailto:hello@yoursite.com)
Visible when Include Internal Links is on. Add pages from your own site — Pricing, About, key service pages — and the blog generator links to them naturally when they’re relevant to the post. Each entry is a page title plus a URL. The URL should start with http://, https://, or /. Good internal links help readers (and search engines) move through your site, which supports your SEO.

​
Topics to avoid

Lower on the Content tab is a Topics to avoid list — subjects you never want the AI to write about or mention. Use it for competitors’ names, sensitive subjects, or anything off-limits for your brand.
  • Type a topic and press Enter or Add to include it; remove one with the × on its chip.
  • It’s free text — add up to 50 topics, and each one can be up to about 120 characters. If you try to add a 51st, theStacc tells you you’ve hit the cap and keeps your text so nothing is lost.
  • This list is soft-steered, not a hard block. The AI treats it as strong guidance to steer away from those subjects rather than a guaranteed filter, so it’s best for tone and topic direction — not for legal or compliance-critical exclusions.

​
A note on article length

There is no per-project “target word count” slider in Preferences. By default theStacc aims for substantial, in-depth posts — its built-in quality standard targets roughly 1,500–3,500 words with strong heading structure — because longer, well-structured articles tend to rank better. The actual word count of each finished post is shown on that blog’s detail page.

​
Advanced and stored brand settings

A few brand fields are stored on your project and used by the AI even though not all of them have a dedicated control on the Preferences page yet:
  • Brand tone — an extra free-text description of your voice
  • Brand colors and brand fonts — used to keep branded visuals on-brand
  • Thumbnail style and infographic style — defaults that shape specific image types
These are saved with your other preferences and will get more surfaced controls over time. For now, the Writing and Images tabs are the main levers, and example articles are the most reliable way to lock in a consistent brand voice.
