I have a legal site started in 2011, which used to rank top 5 for a particular keyword now disappeared to 6th page in google organic rankings.
The site hit its peak in 2017, but dropped in rankings dramatically and never recovered as of Oct 2019. You will see in the graph, the massive drop in Jan 2019, is attributed to converting our site from html to wordpress.
I cant seem to think of any other reason , except competitors reporting by site as spam to google. There is no manual penalty or nothing. I disavowed bad links last month, the rankings slightly improved but as as high as 2017 levels. We have setup 403 redirects of all old pages to new pages when moving our site html to wordpress.
The site has excellent quality content despite this rankings never recovered. I have exhausted all options in SEO.
Which google core update or algorithm hit this site? What could have caused this rankings drop?
Any suggestions will give us some hope.
