— algorithm changes usually expose issues that are already present on large commerce/coupon sites: many near-duplicate pages, thin or supplier-copied descriptions, crawl/index inefficiencies, and missed structured-data signals. and were on the right track: monitoring matters, but next you need a focused diagnostic and a prioritized fix list.

Start with a short checklist (data-first):

  • Check Search Console for messages, Manual Actions, Coverage errors and the Performance report (filter by page) to see which page-types lost traffic.
  • Use URL Inspection on representative product and category pages to confirm indexing and rendered content.
  • Run a small crawl or log-file check to find duplicate URLs, parameter chains, and faceted-nav pages that create low-value index entries.
  • Review product markup and rich result errors so price/availability/review info is accurate.

High-impact fixes to implement next:

  • Replace supplier copy with unique product descriptions and useful buying info; merge or canonicalize near-duplicates.
  • Block or noindex low-value parameter/faceted pages; use canonical tags and parameter settings to preserve crawl budget.
  • Add/validate Product structured data (price, availability, reviews) so Google can trust product signals (Product structured data).
  • Improve page speed, mobile UX, and E-A-T signals (clear policies, contact info, trustworthy reviews).
  • Avoid mass reactive changes after an update; prioritize high-traffic or high-risk pages first.

For what Google expects about site quality and spam signals, see the official guidance (Webmaster Guidelines). If a core update caused the drop, fixes can take weeks to show; track changes in Search Console and iterate.

E commerce website is one of the portal type website, where there are regular updates has been done and the quality of content is not good. so google affects the ranking.
