Welcome to the Q&A Forum

We are an inbound marketing agency, most of our clients are not relying on local seo.  I have a pretty good understanding of it when starting fresh but not so much in joining a "movie in progress" kind of scenario.  Recently we've brought on two clients who have had their websites in place for awhile, have made small attempts at marketing themselves online over the years and its resulted in multiple Google places listings, variations of the company names (one of them changed their name), worried there are yet more accounts out there they aren't aware of, etc (analytics, and others from well intentioned employees and past service providers - no internal leadership at the company level).  In reading Google help forums I'm seeing some recently having their accounts suspended when they try to clean things up - in one case a person setup a new Google account thinking he would start fresh and in trying to claim listings, get rid of duplicates, etc. his account was suspended.  What is the CURRENT recommended course of action in situations like these? With all the changes going on with Google, I don't know which route to take and have combed the Internet reading articles about this (including Google's resources) - would like some current real world advise.

Is there an online resource that has good video tutorials for the basic skills someone would need to make code corrections for SEO related tasks? We would like to make use of some of our internal resources in slogging through some of the tasks of making the corrections. Is there a good training resource online to achieve this?

Thanks for all of the help, I appreciate it.

I do intend to add the filter.  I just wasn't too solid on exactly how to go about the code in sites still running classic to get things done.  Again, I appreciate the help.

We are a Hubspot partner agency.  I'm trying to find the best route for managing Google's tools as an extra resource for insight, not the primary basis for marketing effort.  I also want to explore adwords in more depth. Finding a lot of our clients don't have one or the other or both Analytics/Webmaster tools in place.

1. Can I verify site ownership to set up webmaster tools simply by having admin access to their analytics account or will that require ownership of the analytics account? With Google merging things together these days I'm not sure of the best approach to take.
2. Usually clients have their site hosted somewhere and built on some platform and ADD a Hubspot blog and the landing pages/cta's, Hubspot tools on a subdomain hosted by Hubspot.  Hubspot has tools in it's website settings for adding google analytics (actually it's just a field to add code to the header area).  If a client has universal analytics on their primary domain do I still need to go and add a separate analytics property for the subdomain and go through Hubspot's tools to install it on the subdomain? Or just use the same code from their primary domain and add it to the Hubspot header?  What is the best route?

Any additional thoughts on this subject are welcome - with so much updating and changing coming from Google (and Hubspot as we implement 3.0 - COS) I'm trying to avoid wasted effort, outdated methods, etc.

Thanks!
