Issue with Latest Google Update of March

Hello All,

Following the latest Google Update, a client of mine lost 20% of traffic for the English version of his site.

I noticed few things on his site.

1/ Mega Menu with more than 60 links.
2/ Comparison table of the product he is advertising which are not responsive and links are do follow in those tables.
3/ Some issue in the content (wrong spelling and grammar mistake).
4/ Missing Meta + Missing SEO Title on some articles.
5/ Some pages contain several times the same internal link (read this review) (learn more) ....

Their backlink profile is strong more or less in line with their competitor in term of metrics and velocity. (no anchor spam and good diversity of links).

Overall their content is good with more than 1000 words for each article and they have more than 400 position in top 3 ranking.

Do you think one of the reasons for the traffic loss could be point 1/2/3/4/5 ?

Thanks for your opinion

no one ?

Could be anything, actually. Many of my colleagues have been deindexed and most of them still haven't figured it out. But if I were to speculate among the ones you've just mentioned, I'll go for 2, 4 and 5.

3, 4, 5 can be minor points while i don't believe 1 and 2 can be the cause. maybe the google fluctuation is going on and will settle after some days.
