Old way of doing SEO by spamming Google

Hello,

I am a web designer / developer and rather new to SEO. I’ve been charged with redesigning the website for a branding design agency seenk.com/en/ which feels to me very over-bloated. For exemple on the “Expertise” page there are links to pages that briefly describe all the different type of content we create (see photo attached). This is the demand of the companies SEO expert claiming that these are all entry pages that help with the sites ranking.

My question is are these pages really necessary in helping with the websites ranking? I don’t see any other design agency doing this sort of thing. To me it feels like a very old way of doing SEO by spamming google with all the possible keywords we can give it especially considering that some of these pages have very little content on them. Being the kind of minimalist person with a "less is more" attitude, I would like to get rid of these pages or at least regroup some of them if at all possible.

Thanks for any help you might have.
