Microsoft Dynamic Search Ads (DSA): Inventory Mining Strategy (2026)

Dynamic Search Ads (DSA) do not use keywords. They use your Website Content.

• User searches "Red Nike Running Shoes Size 10".
• Bing crawls your site -> Finds the exact product page.
• Bing generates a Headline: "Red Nike Shoes - Size 10".
• Bing lands the user on that exact page.

In this "Mega-Authority" guide, we cover:

1. Use Case: Large inventory (Ecom / Real Estate).
2. Page Feeds: Controlling the crawl.
3. Negative Keywords: Essential hygiene.
4. Ad Copy: Static Descriptions.

Part 1: Page Feeds (Control)

Don't let Bing crawl your whole site (About Us, Privacy Policy). Use a Page Feed.

1. Create Spreadsheet: Page URL, Custom Label.
2. Upload to Business Data.
3. Target only URLS with Label "In Stock Product".

• Result: Ads strictly for products you want to sell.

Part 2: Static Headlines

Wait, DSA generates headlines automatically? Yes. And they are usually great (Keyword Relevant). But the Description Lines are static.

• Write generic USP copy: "Free Shipping. 30 Day Returns. Shop Official Store."
• Let the Headline do the specific lifting.

Part 3: Negative Keywords

DSA is a "Vacuum." It sucks up everything your keyword campaigns missed. It also sucks up junk. Strategy:

1. Add your Brand Name as a Negative Keyword (Keep Brand in a separate Manual campaign).
2. Add "Support", "Login", "Returns" as Negatives.

Part 4: DSA as a Research Tool

Run DSA for 30 days. Check the "Search Terms Report." You will find keywords you never thought of. Harvest: Take the winning search terms -> Add them as Keywords in your Manual Campaign (Exact Match) -> Bid higher.

Part 5: Summary & Checklist

Your Action Plan:

1. Create a DSA Campaign.
2. Target "All Webpages" (or use Page Feed).
3. Exclude blog posts and policy pages.
4. Review Search Terms weekly to harvest new keywords.
5. Benefit: +20% Traffic Volume with 0 keyword research.

SEO meets PPC.
