We have over 1,000 keywords resulting in our pages in SERP from 48k impression giving 117 clicks (worst case) to 1500 impressions fetching 437 clicks (best case).
I understand that relevancy is KING these days and I'm only referring to the relevant and super useful content with very low CTR.
1) Is building similar content and doing internal backlink to the older page will help?
2) OR create new skyscraper content and older content point link to the new one?
3) OR building external social media links will help?
4) OR building external high DA / PA links will help?
5) Please share any other ideas or suggest the best option from above.
Thanks in advance.
