I have 2 websites (.co.uk and .com in same niche EMD's) that I optimized for the main keyword, after the Google algo updates the site has dripped from top 100 pages (.com) I also checked the backlinks and found alot of toxic links from a competitors seo guy (he worked for me) and offered me Negative SEO for competitor that I turned down, it looks as though he has done it to me! I site has had the links disavowed and links built this was #1 for 2 years and now it is on page 4!!! (.co.uk) I am about to disavow the toxic links on .com site. Looking at ahrefs I have over optimized the main kw, as it stands at 30%, I have started using the url to rank for but that is only at 4%. How can I increase the links for the domain name without completely screwing it up? We have been posting unique content on the blog attached to the domain but nothing is improving the domains position, I have been told to hold off making any backlinks due to the current changes in Google - this was from a guy offering me quality backlink hire. What can you suggest to get results and what have I to avoid? Please let me know, I am going crazy!!!!!
