One client (Domain authority 47 ranks for 100s of tough brand related keywords) and had duplicate content on its internal brand pages (the same few 100 words of brand info on each brand page) and was hit badly.
We have other clients in this vertical (Mens designer clothing in UK) , some with duplication have increased in rankings, but they might have a slightly higher Domain Authority 50).
All the ranking drops happened on April 12<sup>th</sup>, across all pages which had internal duplication (you can see traffic drops by dissecting brand pages in GA).
We have re written all content and placed it on all pages so there is no internal duplication. All the new content has been there for a month and each page has been cached. No change to our rankings.
Anyone know if the changes they have made have seen any improvements? Surely if this algorithmic then once the algorithm picks up the changes then it re-assesses you and will change your ranking? Surely you can’t now be a ‘marked’ domain???
