Chat positioning & layout
The ShopGuide bubble is always a fixed floating bubble anchored to a bottom corner. So this page isn't really about page-by-page placement strategy — the bubble's position doesn't change based on where in the page you add the block. It's about the real configuration options and staying out of the way of everything else your theme puts in that corner.
How positioning actually works
The bubble sits at position: fixed, 20px from the bottom of the viewport, and either 20px from the left or right edge depending on your Bubble position setting. It stays put regardless of scroll position, and regardless of which theme section the ShopGuide Chat block happens to be attached to. There's no sidebar-embedded mode for the bubble and no multi-window placement. On phones, a started chat takes over the screen; see Mobile & desktop chat settings.
What you can actually configure
In Settings → Bubble: position (left or right), size (default 60px), icon (Sparkles (AI), Chat, Message, Question, Robot, Search, or Custom image (upload)), icon color, and whether the bubble shows at all. The bubble size slider (Bubble size (px)) runs from 40 to 80.
With Custom image you upload or pick a square image (PNG with a transparent background for logos, JPG for photos). Fill the whole bubble crops it to a circle that covers the bubble; with it off, the image is centered inside the bubble color. The icon color picker is hidden while a custom image is chosen.
Picking a corner
Since it's fixed to one corner either way, the real decision is which one avoids conflicts with whatever your theme already puts there. Right is the default and the more common choice for chat widgets, but check for a sticky "back to top" button, a cart drawer trigger, or a cookie-consent banner that also lives bottom-right. Left works well if your theme's cart icon, sticky add-to-cart bar, or promo banner claims that corner instead. On mobile, check against your theme's own bottom nav — if it has one, turning on "Store has mobile navigation bar" (see Mobile & desktop chat settings) shifts the chat's notification bar to avoid it.
On z-index
The bubble sits at a very high z-index, above most page content and most modals. If something specific still overlaps it — a custom cookie banner, a third-party app's own fixed element — that's a conflict on the other element's side, not something ShopGuide's settings control. See Advanced chat styling if you need to adjust the bubble's own styling to work around it.
What not to expect here
No per-page-type positioning presets for homepage vs. product vs. collection, no scroll-triggered position changes, no A/B-testable coordinates, and nothing like "above the product grid" or "in the sidebar." Page-specific customization in ShopGuide happens through the launch message and buttons, not the bubble's screen position — see Custom launch messages.
When something's wrong
If the bubble isn't visible at all, check whether the storefront is switched off with the Global Kill Switch in Settings, check that the block sits on the page you're looking at, and look for a competing fixed element with an even higher z-index. If it's overlapping other UI, try the opposite corner, turn on the mobile-nav accommodation if it applies, or nudge the bubble's offset with targeted Custom CSS (see Advanced chat styling).
