I kindly need advice before I make mistakes.
I have a website which is 1 year old, it never ranked pretty well, At it’s best, it ranked for 43 keywords and all on lower google serp positions i.e page 3, 4, 5.. and after some little time, the website lost all those rankings and currently it’s getting about 8 impressions per day, one thing am pretty sure I was doing wrongly is creating low quality and thin content. The website has no manual penalty as per Google search console. Now am thinking about starting over and do things right, how should I go about it?
1. Should I continue with this domain, delete all old content (pages and posts) and start creating High quality long content.
2. Should I abondon the domain and and start over with fresh new domain so as not to continue wasting time on a website which will never rank
NB. Am afraid to continue wasting time working on this domain because I think that maybe its facing some kind of algorithm penalty and hence will never rank (not sure though, am newbie to SEO).
Is there anyone else here who think the website is suffering an algorithm penalty? If yes, will the website rank if I delete all the old duplicate, thin content and add original high quality content?
