local SEO site, was ranked on front page for over a hundred of terms, over 100+ pages concerning construciton... BUT site also contains 60+ pages of unrelated content about loans and paydays loans... which concerned Panda 4.0. lost almost all rankings to page 6+. Panda 4rolled out May 19th-20th. We noticed the drop around june 13th . I don't believe Panda 4.0 would hit all search queries and sites from May 19th-20th... there would be some lag time right? Around June 8-10th we also relaunched 21 pages and did onsite SEO. I did H1-H6 tags using variations of exact keyword in sentences of H1 tags. exact match long tail KW density is at around 11 repeats, 2.65%. Added 500 words fresh content to each page. added 3 images to each page... all the same images, but we renamed them for variations of KW, i.e. KW-1.jpg, KW-2.jpg, KW-3.jpgetc... Added ALT tags to images, variations of exact match KW too. Racking my brain on this... hope someone has a bone to throw me. I thought to delete all loan pages from server... but it's strange how at the same time we relaunched SEO pages just a few days before when this drop occurred.
