Welcome to the Q&A Forum

Hi There, Yes, pages with less content and only images can hurt your site's SEO. Another problem with portfolio pages is that with the limited content, similar title and description, they might look as duplicate to search engines. I have a client who had limited content on product pages, we had great success in SEO after adding a unique description to pages. Best to handle the situation is to use a portfolio main page with unique on-page content. I hope this helps. Please respond if you have further questions. Regards, Vijay
