I took on a client in April in the travel sector at the time they were at position #71 for their target phrase
They had maybe 500 links of which 250 seemed toxic. I created a disavow and uploaded it.
Since then I have replicated all the good links their competitors appear to have.
I've added blog posts to reputable travel sites, posted in forums, exchanged links - each time checking for link toxicity.
Some of the links I added have a good domain authority score and page score using the Moz tool.
But nothing has moved not even a single position. Yes there is the odd random up and down move on a daily basis. But the average position is unchanged.
Other sites I work on respond well to this approach.
Could it be a Penguin Penalty? There is no manual penalty notices in their WMT account.
Its strange but I can't understand why otherwise its not moved up to say page 3 or 4
Any advice appreciated
