Please accept my apologies for not making it more clear.
This websites was disappeared from Google in fist week of October.
And this is not a manual penalty as I checked in webmaster tool
I checked back links deeply and found such type of facts,
Links from these domains
Also exact match was used for 80% links.
Further More, Site structure is very poor right now and built in Html.
One keyword is targeted on different pages.
Family keywords are targeted on separate pages for example,
Yacht charter and yacht rental have different pages.
So I suggested to upgrade it wordpress and as we are going to shift new URLs so its better to target relevant keywords on one page.
Also as we are building new URLs so I can apply earlier mentioned strategy. Mean I will not redirect previous pages to new built pages in wordpress.
Actually most of the backlinks built were kind of spamming like getting too much links from same domain.
So if I use only home page and leave all other pages it will help?
Also I have submitted most of the poor links in disavow already. Nobody exactly know how much time disavow takes?
Also exact match and multiple links from same domains can still effect.
