AI-Powered Analysis

Personalized insights generated by our AI

TopScan’s visibility is low (21/100) due to poor keyword coverage and low ranking in core OBD2 terms, despite a strong primary keyword rank and decent quality score. Immediate focus should be on expanding and optimizing keyword usage and boosting user ratings.

Top Keyword Dominance
high

The brand name "topscan" ranks #1 with traffic 76 and moderate difficulty (34), driving a portion of organic installs. Leverage this by keeping the brand at the front of the title and using it in the short description.

Insufficient Core Keywords
high

Only 5 of 10 target keywords rank, and critical terms like "car diagnostic tool", "auto diagnostic", and "obd2 code reader" are not ranked at all, missing 40‑50% of potential traffic. This drags the Keywords Score to 24%.

Low Rating & Reviews
medium

The app holds a 3.1‑star rating from 1,113 reviews, well below the 4‑star benchmark for Tools category, negatively affecting quality score perception and conversion.

Title & Short Description Optimization
high

The title currently lacks high‑traffic keywords such as "OBD2 scanner" and "car diagnostic" (traffic 73‑76). Adding 1‑2 of these terms can improve relevance and keyword rankings without exceeding the 30‑character limit.

Enhanced Visual Assets
medium

Charts score is 0% and there are no rankings in category charts, indicating weak click‑through. Refresh screenshots and add a short demo video that showcase key features (e.g., Bi‑Directional controls, AutoVIN) and embed primary keywords in image captions.

Localized Keyword Expansion
low

Competitors rank ahead for shared keywords in English‑speaking markets. Localizing the listing for high‑traffic regions (e.g., US, UK, India) and incorporating region‑specific synonyms ("bluetooth obd2", "vehicle diagnostic app") can capture additional traffic.

Key Action Items
Priority actions to improve your app's visibility
  • 1Rewrite the app title to include "OBD2 scanner" or "car diagnostic" while keeping "TopScan" front‑loaded.
  • 2Add top‑performing keywords (e.g., "obd scanner", "bluetooth obd2", "vehicle diagnostic app") to the short description and early sentences of the long description.
  • 3Launch an in‑app prompt and email campaign to encourage satisfied users to leave 4‑5 star reviews, aiming to raise the rating above 4.0.
  • 4Refresh screenshots and create a 15‑second video highlighting Bi‑Directional controls and AutoVIN, embedding primary keywords in image captions.
  • 5Implement localized listings for US, UK, and India with translated descriptions and localized keyword sets.
