When i search for my published tours in google (using the whole link), the actual tour page doesn't appear in the search result but the archive page (tour category page). why is this happening ??? BTW pages were published pretty!

Hello Everyone, i need some expert help here: I was uploading photos in my website and so many advised to use (webp)format which is a great quality in such small size compared to JPG. But the issue is, i noticed that i can't add a photo description, tags or keywords to the photo info. When i do and save using photoshop it is blank (i checked with other and seem to be, this is the type of photo, no info can be saved). The question is, is it better to use JPG type, add description, tags, keywords and photo info since it will be better for the website SEO or it won't make any difference ?
