The biggest traffic mistake I made that isn’t in the post: sending paid traffic to my homepage instead of to specific product pages. 
For the first six weeks Sellvia Ads was driving people to my store’s front page. Some of them found the product they wanted. Most didn’t. Switch to sending traffic to specific high-converting product pages happened in week seven. Conversion rate went up immediately. The homepage is for people who already know your brand. Paid cold traffic should land on a page that immediately shows them the specific product relevant to what they clicked on. This is basic funnel logic that I completely ignored for six weeks while wondering why my add-to-cart rate was low.
Wait - can you actually configure Sellvia Ads to send to specific product pages rather than the homepage? 
I’ve been running for eleven months and always assumed the built-in system just sends to the store homepage. If there’s a way to direct traffic to specific product pages that would potentially change my conversion rate significantly.
Honestly I should clarify - I was talking about the organic channels (TikTok link in bio, Pinterest pin links) rather than Sellvia Ads itself. The built-in Sellvia Ads system controls its own landing page targeting automatically. But for organic channels where you control the link - TikTok bio link, Pinterest pin destination - pointing those to specific product pages rather than your homepage makes a meaningful conversion difference. My apologies for the unclear framing.
The post should be required reading before anyone asks “why aren’t I getting traffic” in this forum. 
The answer is almost always one of two things: either Sellvia Ads hasn’t had enough time to optimize, or the store owner is relying entirely on one channel and expecting it to do the work of three. Both are solved by the same thing - patience and diversification. Neither requires spending more money.
Twelve months in. Current traffic split: Sellvia Ads 54%, Pinterest 22%, email 16%, YouTube Shorts 5%, direct 3%. 
A year ago it was 100% Sellvia Ads. The blended CPA dropped from $8.90 in month one to $3.70 now. Same niche, same products, same base ad spend. The only thing that changed was adding channels that cost pennies per sale. The math on traffic diversification is not subtle. It’s the difference between a business that’s marginally profitable and one that compounds.
