Tech SEO is where the highest SEO increment is achieved in eCommerce.

Why Technical SEO Matters in eCommerce?

Search engines must access, crawl, index and serve your site's pages in their results correctly before you can rank. For eCommerce, this means:

  • Managing thousands of URLs from product listings, filters, and pagination.
  • Preventing index bloat, crawl waste, and duplicate content.
  • Structuring your site for maximum retrievability and semantic clarity.
  • Ensuring speed and perfect rendering across all devices.

CASE STUDY: VIDEO CLOUD HOSTING

How Cincopa increased their organic traffic by 148% and conversion by 35%

Lior and his team new that their blog was not performing well enough. Despite the fact that its was one of the major client of clients.

It was slow to index and slot to gain traffic. So, it both had a technical SEO problems and the lack of coherent Content strategy.

The content was a little too biased toward design and layout topics with an evident lack of user facing and educational content.
