Is there a tool or a method or standards that this website is worth more SEO'ing or just forget it? I have a website back from 2013 which has ranked for its certain keywords and some even top 1 and I stop SEOing weeks later i went down the hill and never on the top 100 again up to now. backlinking done back 2013: 1. Bought Homepage high pr links 2. Tier SEO 3. High Quality GSA Blast (Acquired 1K Backlinks only) backlink profile based on ahrefs: Now, i was wondering if i can continue doing SEO with this website? The reason is I have put so much effort on this website pure html 5 page landing page with high quality content and custom scripts not to mention it's PR1 already.
