For me, I work it like this. if it is not hurting my rankings or user experience I would not change it. the risk is pretty high if it's not done right and I don't think you will gain enough out of it to take the risk.

Are you wanting to change it because you feel it will help with rankings?

if you didn't build the links or earned them through good content and you don't feel they are good. Always better to just disavow them. Even more so if they are .ru sites as I am sure your site is not in Russia

I personally love https://sucuri.net to fix issues like this.

So you need to take two steps, the first one is you need to work out if someone is hacking into your site by using sucuri you can check. They will also do a clean up if they find something. To find the page they hacked into you can also look at where these links are pointing to.

The second part is you need to do a disavow of the links going to the hacked page. As this will also be hacked sites most likely or cheap links. Here is the link to do a disavow, you do this through search console.

Good luck and if you need anything else let me know.

I would most likely use event tracking as it means you don't need to move the user to another page. You can program it into the website to send the data as it happens.

Here is a good page about setting up event tracking Click here

Just wanted to add that than you could setup goal tracking from the event itself once setup. This will allow you to track conversions better or non conversions.

Hi Donald,

I normally stay away from yellowpages as google can see this as spam and even more so when you have 2500 coming from one site. I normally disavow them altogether. If they acted like a other local listing sites and didn't give so many links it's fine but yellowpages is known to do this for sure.

Local Citations can be a great part of your link building but you need to be careful and insure its done right. Here is a page Moz has put together https://moz.com/learn/local/listings about local listing/citations and why you should do them and how to get started.

Hope this helps.

Sadly there really isn't one. I know it doesn't help but the 301 shouldn't have been done in the first place. Changing URL's and doing 301's always impact on rankings in a big way.

You will be best to 301 the new domain back to the old one and try to stay away from doing it. Also keep in mind every time you do a 301 you will only get 70-80% of the benefit of the links going to that domain.

I would be very careful when Changing 301s I have seen people have major issues when turning a 301 off. More so because a lot of people use 301  to drop spam backlinks and get a jump in rankings.

Can I ask why did you do the 301 in the first place? And are you going to 301 the new domain back to the old one.
