Affiliate Disclosure

Last updated: April 2, 2026

In the interest of full transparency:

SpotOnAuto (operated by Widescope Industries LLC) earns money through affiliate commissions and advertising. Some links on this website are affiliate links, meaning we may earn a commission if you click through and make a purchase — at no additional cost to you. This is how we keep the site free and continue building tools for the DIY auto repair community.

How We Make Money

SpotOnAuto is a free website. We do not charge users for repair guides, diagnostic tools, wiring diagrams, or any other content. We earn revenue through the following channels:

1. Amazon Associates Program

SpotOnAuto is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com.

  • When our repair guides recommend parts (oil filters, brake pads, spark plugs, etc.), we link to those parts on Amazon.
  • If you click an Amazon link on our Site and purchase anything within 24 hours — even items we did not link to — we may earn a small commission (typically 1–4% depending on the product category).
  • Amazon affiliate links on our Site are identified by our Associates tag: aiautorepair-20.
  • Prices shown are provided by Amazon and may change. We do not control Amazon's pricing.

2. TOPDON Affiliate Program

SpotOnAuto is an affiliate partner with TOPDON (topdon.us), a manufacturer of OBD2 diagnostic scanners and battery testers, through the GoAffPro affiliate platform.

  • We earn a 5% commission on TOPDON products purchased through our referral links.
  • TOPDON product recommendations appear on our DTC code pages, live diagnostic tool, and dedicated comparison guides (e.g., Best TOPDON Scanner).
  • We recommend TOPDON products because we believe they offer good value for DIY mechanics. Our product recommendations are based on the diagnostic context (what code you're reading, what system you're diagnosing) — not commission rates.
  • TOPDON referral links on our Site use the referral code: spoton.

3. Google AdSense

We display advertisements on some pages through Google AdSense. These ads are served by Google and may be personalized based on your browsing history (per Google's ad personalization settings). We earn revenue when visitors view or click these ads.

  • Ad placements are clearly distinguished from our editorial content.
  • We do not control which ads Google displays on our pages.
  • You can manage your Google ad personalization settings at adssettings.google.com.

What This Means for You

✓

You never pay more. Affiliate commissions come from the retailer, not from you. The price you pay is exactly the same whether you use our link or go directly to the store.

✓

Our content is not influenced by commissions. Repair guides are generated from OEM factory service manual data and AI. We recommend the right part for the job, not the part that pays us the most.

✓

Product recommendations match your diagnostic context. When you look up a DTC code, we recommend the scanner tier that actually reads that code — not the most expensive option.

✓

We only partner with products we stand behind. We chose Amazon because most DIYers already trust and use it. We chose TOPDON because their scanners offer strong value at each price point for the DIY community.

FTC Compliance

This disclosure is provided in accordance with the Federal Trade Commission's (FTC) Endorsement Guides. The FTC requires that affiliate relationships be clearly disclosed to consumers. We are committed to transparency and will always identify affiliate links and sponsored content on our Site.
