Welcome to the Q&A Forum

Tyson, Google's mobile and desktop algorithms are different--so that's why you're seeing different results. As Ruben mentioned, there may be mobile issues that you can fix or optimize for, which will help your site rank better in the mobile search results.

I took a look at the results for your site in Google's Mobile test https://www.google.com/webmasters/tools/mobile-friendly/ and it's mobile friendly, but the WebPageTest.org results show that it definitely needs to be cached--you should set up a CDN such as CloudFlare in order to cache the pages on the site.

If the old domain has a penalty, you should be able to get that penalty lifted/removed/revoked. Then, later on you should be able to go ahead and redirect once the penalty is removed.

One of the concerns, though, is that if you redirect ANY page from the old domain to the new domain you may pass on the penalty to the new site. We recommend getting rid of the penalty on the old domain first--and then consider dealing with the issue of redirecting the old to the new domain.

Ruben,

Most URL shorteners use 301 permanent redirects, and some of those 301s aren't actually nofollow links. It depends on where the shortened URL appears. While Twitter links are typically nofollow links, there are sites where they aren't. For example, did you know that the full URL, when shared in LinkedIN in the description is not a nofollow link? It's shortened, but it's not nofollow.

From what we can tell, Google really does use social as a ranking signal, and if they can see that real traffic is going via social media to a URL, then it will rank well, even if it has a nofollow tag on it. What you're seeing is the power of social media to rank something and to link to something--which you should be doing if you want to rank as well as your competitors' sites.

Depending on the Domain Authority of the domain(s) that are linking to you, it would or would not be helping or hurting you. When evaluating links that are sponsored like this, we typically recommend looking at the traffic the site is sending. If you can clearly see traffic from the site and those clicks are converting for you, then you should probably keep those links.

If they are sponsored links, though, and they're in the sidebar, they should be labeled as such--and they should be nofollow links.

With 10 URLs ( I think you mean 10 different domains?), you should be fine. If those URLs have a lot of links pointing to them, though, there could potentially be an issue. So, if there were 1,000 links to each one, then you'd be redirecting 10,000 links. It really depends on how many links we're ultimately talking about.

I have seen situations where thousands of domains were redirected, and that was a problem--it was also a problem with about 100 domains redirected, as they all had links pointing to them.

What I would do is look at your analytics to see which of them are actually sending traffic to your site, which ones have links pointing to them. Then only redirect the ones that have traffic and links and ones that are on-topic.

Typically, links from multiple subdomains on the same IP address aren't recommended or wanted. It's links from separate websites that are on unique Class C Blocks of IPs. This way we know that most likely each site is not owned by the same site owner.

Just on a side note, typically we don't recommend getting a lot of links from blogspot sites. There are unique cases where a link is okay, but we don't prefer blogspot links.

Oleg is right, you should be using canonical tags in this case. However, keep in mind that you can also tell Google, in Google Search Console, which parameters to ignore. If you're using tracking parameters on a regular basis then you'll want to do that, as well. And you should tell Bing Webmaster Tools, as well, to ignore those parameters.

Another option is to list those parameters in your site's robots.txt file so that they're not indexed.

The first thing I recommend is to make sure that those are actually 404 errors on your site that the search engines (and regular users) can see. There is a link spam technique out there that is used to hide actual links from the site owners. So, if you are logged into your WordPress site, for example, the links and pages won't appear to be there. But, if you are logged out then the pages will be there, visible to the search engines and the public.

I would look in Google to see if those 404 pages on your site are indexed. Try a site:yourdomain.com search to see if they're indexed. Then, use a crawler to crawl your own website to see if the crawler can find those 404 pages.

Typically, when you see those errors, the site has been hacked and now they've been removed. Or, those pages are on your site but when you go to them they appear to be 404s. I recommend you investigate this further to make sure that the pages or the errors do not exist.

Brain, based on the example you provided, Google is correct--there is no proper meta description tag on those pages, so that's why they're not including your meta description tag. If there is no meta description tag, then Google will just show text from the page.

For example, the syntax of your meta description tag on the /7175 page is incorrect.

Bob, generally speaking it's best to redirect users to the page that's most appropriate. Think of the users and what page they would land on--and be redirected to. If they were looking for an old product page and just redirected to the home page, would that be frustrating for them?

When it comes to an actual search engine ranking lift or boost, you most likely won't see one. You only would just not rank anymore for those products that you used to offer. There still may be a boost if you were to redirect an old product page to another page and there were links pointing to the old product page from external websites. Then, the boost might be passed on to the product page you redirect to.

You really should be using Google's parameter tool if you do NOT want those pages crawled.

If they are crawled, and you use the canonical tag in order to tell Google to pass any "juice" to the page you're setting the canonical tag to, then you won't lose any traffic. Both of those URLs (the one with the parameters and one without) essentially will be crawled, but won't be indexed.

Whenever you move, here's what we typically recommend:

• crawl site, make note of URLs
• set up redirect of old URLs to new URLs
• test to make sure they're a proper 301 redirect
• verify all versions of the site in Google Search Console (old site and new site, http and http://www versions as well as https versions)
• Use the Google Change of Address Tool

Whenever you migrate a domain name to another domain name (I think this is what you're saying you did), Google will keep the URLs of the old domain name in their index for at least a year. That's if you migrate to a new domain name.

If the pages have 301 redirects to other pages on the site or new pages on the site, then those old URLs could still remain in the index for a period of time--you'll be able to see them if you search for the URL.

Typically even if those URLs are still indexed, it shouldn't be hurting rankings at all.

When it comes to hosting images off site, keep in mind that there may be connectivity and image load speed issues associated with these images. I typically wouldn't rely on an image being pulled from someone else's site, even if it was something like Flickr or Photobucket. I don't think those particular services intend for you to use their service like that.

Rather, we typically will set up a CDN for hosting the images or PDFs, and use a subdomain of the main site in order to host the images. For example, we would set up images.domain.com and pdf.domain.com and put the images and PDFs on the CDN.

Issa, there are plenty of Google algorithmic penalties that a site can have, like the Google Panda and Penguin penalties, that do not show up in Google Search Console. These can be tough to diagnose, and even when diagnosed they're can be tough to fix or can take time to fix.

What I would do is look at the Google Algorithm change history (https://moz.com/google-algorithm-change) and compare the date(s) where the site had traffic drops with the dates of algorithm updates. That should help diagnose some of the issues the site is having.

We moved a lot of client sites over to HTTPs from HTTP. We always use the proper 301 Permanent Redirects, and there is no loss of rankings as far as we can tell. When it comes to links in particular, if you 301 redirect one page to another on the same domain name, you will NOT lose any link value. The key here is that it's a redirect on the same domain name.

If you are moving from HTTP to HTTPs, make sure you verify the site in Google Search Console and update Google Analytics, as you will see a loss of data if you don't update those.

The most popular sitemap plugin for Magento appears to be this one: https://www.magentocommerce.com/magento-connect/xml-sitemap-generator-splitter.html, the XML Sitemap Generator & Splitter.

Unless you are going to have all of the products listed on the domain.com/products/ page, then you should consider getting rid of the /products/ directory altogether. It serves no purpose if you're not using it, and only lengthens the URLs.

During these events we show them the "behind the scenes" of our company as well as the manufacturing process and give them an amazing experience surrounded by our products.

I believe that that qualifies as promotional--you are giving them a perk that others don't normally get. So, those links should probably be tagged as nofollow links. The post or article that is written should include an explanation that the writer was invited to the event--which would be clear when reading what they posted.

Keep in mind nofollow links aren't always a bad thing--it's logical that your site have both links that have nofollow them and links that don't have nofollow on them. It's ultimately up to the individual blogger or author/site to decide, though, and I wouldn't obsess over these links.

The way you're going about it sounds just fine--as long as it makes sense to you and is logical. I recommend you use a keyword classifier (such as ads, careers, location, etc.) in the URL so you know which ones are which ones.

We typically have had up to 50,000 URLs in one sitemap.xml file and then it's split up. Some of the files may contain less, but typically that's the maximum.
