which is better text links or graphical links for seo?

Text links are better for SEO. Text links can contain the anchor text that our web page wishes to rank well for and that is an important factor in many search engines, especially Google. Image links are still valuable but do have less benefits compared to text links.

Text links hold more SEO value than image links. Putting text beneath an image and linking both is a good alternative to linking an image with embedded text. Don't replace image links with text links if this will compromise the user experience. Make sure important pages don't only have image backlinks.
