Since the onclick event is a Javascript issue it's to all intents and purposes ignored by the search engines. What counts is whether or not your link appears in the href attribute, and whether or not the link is nofollowed. If you do not have it set to nofollow, there is a slight chance they would follow it, but as stated above, Google is pretty good about parsing javascript links.

Most of the crawl programs we use say to keep on page links (including navigation) to under 100 per page for best crawl-ability and indexing by search engines. Having an excessive amount of anchor links on one page could have the adverse effect of what you are trying to accomplish, and potentially hurt that page's value.

The best way it can be said is: Will having a lot of anchor text links benfit the user of the site? If it makes your site easier to navigate, or serves another purpose, then set up the page that way. DO NOT try and design a page solely around a search engine to artificially gain rank or placement.

"remove listings from the index due to there being too much similarity with existing locations"

But wouldn't that be for multiple listings, that had similar or exact addresses? (for the listing itself, not the website) But I do agree it's a risk to have both.

I agree if a competitor saw both ranking, they could submit it as spammy, but technically, he isnt breaking any "rules" by having two sites. Having the same content on both, yes.

Good points on your end, not discrediting any of them. I see what you mean, I'm just trying to let the OP know what he is potentially up against by having both.

Some of the page titles on each site are the exact same. The content is different, and the descriptions are different, so you might be able to get by on that.

The contact pages being so very close is worrysome. I would mark up one with snippets, and the other without. Also, your domain names are very close. Have you seen any adverse effects in ranking due to this?

After looking at the two, I would invest a bit more into the http://gtawindows.com/ domain. Personally, I think it looks better, and google seems to rank it better according to keywords like "vinyl windows toronto", and "entry door toronto".

Noticed a few errors you will want to look at:

Script error that is affceting a few pages:
http://gtawindows.com/patio-doors/patio_door/

Duplicate pages due to tagging system:
http://gtawindows.com/toronto-exterior-doors/
http://gtawindows.com/tag/fiberglass/

http://gtawindows.com/tag/ontario/
http://gtawindows.com/tag/handles/

There are quite a few more. I would invest some time in looking at this, unless you already have them blocked in robots. Do a site search, and look at page 11 results and beyond.

Hope this helps.

Alex, post the links to domains. I would like to see what you have in place. They are no-follow, so it shouldnt be an issue.

Wanted to include the links to the tools I used to find this info. I would bookmark them for future reference.

Take a look and see what category is a best fit for your business markup.

I agree with only having one marked up, but I would still submit both. If the content is different between the two, I don't think there will be any issues with ranking. If they are similar, and you have 2 domains saying the same thing, that could have a negative effect.

As to having 2 domains, is there a specific reason you have it set up this way?

@william do you have evidence of having location info listed on both sites causing an issue? I'd like to know more about the potential issues this could cause if you have seen it cause trouble before. You mentioned that it would cause issues with getting listings accepted, but since most listings are verfied by phone or by postcard, I cant see how having it displayed on multiple sites would have an impact on the acceptance or validation of the listing, simply because it's displayed on more than one domain.

You'll need to request all ad groups in the campaign and choose the one with the same name.

It is possible to get adgroup id. It is part of AdGroupAd type, and can be retrieved using "AdGroupId" as selector name. Then you would retrieve the field as $googleAd->adGroupId. More details here:

Lots of questions come to mind.

1. How old is the site? (how long has it been live?)
2. How optimized is the content? New doesn't mean good.
3. You mentioned there aren't any bad backlinks, are there any good ones?
4. Does a sitemap exist? Has it been submitted in Webmaster tools?

A few things I noticed:

I ran the site through SEO-browser.com, and saw you have headings above your first H1. This tool allows you to see your site the same way a search engine does. There isn't a lot of content on the home page either, only 1 paragraph above the fold, and most of it is bullet points.

The blog page only has 2 posts. One has a broken image path. The blog on this site does not seem to be used effectively.

On the pages I looked at, there are not a lot of internal links encouraging people to explore the site. I have noticed that Google tends to not like "dead end" pages. Consider adding links both internal and external from your pages, and expanding the content.

Even though you have the Google+ link, authorship is not set up for the website. I would add more validation links to existing citation profiles, or if they dont exist, create some. In the "Extracted structured data" there is required structure missing for that snippet to work properly.

Site appears to be focusing strongly on finance, might want to expand to the active term, "financing", and check google trends and keyword tool to see if that is more popular.

Footer location info is not marked up in rich snippet format. You can view how to do this here:
http://www.schema.org/Organization

Site index shows a default wordpress page being indexed:

All pages have a page title with the company name, rather than focusing on the subject matter page is about.

No keywords in backend seo.

That should give you a good start. Hope this helps!

There are a few ways to look at this.

As long as you have to resources available to properly optimize both sites, and provide distinct, separate content, then no, there should not be any adverse affect to your seo or ranking.

I think it's wiser to invest your efforts in one site, but I can understand the cause for a separate site, particularly if it is using a keyword-driven domain name.

Sorry to double post, but I went and looked and they also have one specifically for local business.

I think adding the map by itself couldn't hurt, but I would combine it with schema organization or business markup  for the best results. You can specify where your physical location is with either of those two mentioned.

I'm not sure if I would do it that way.

First, look at your analytics for each language, and see which ones it makes sense to accommodate. Remember, it's not just setting up all the profiles, it's also having to update them all separately. Extra time spent for how much of a return? Also, because of your business type, will people really interact with the social side of your business? Or are you setting it up solely for search engine validation purposes?

I'm not an expert as this, but I'm betting most platforms have a translator built in. Here is a link I found for Facebook. You probably want to check out the others for yourself and see what is available.
