Welcome to the Q&A Forum

Yes, in your example it WOULD affect the ranking, as the first URL no longer exists. Ideally the 1st URL should 301 redirect to the 2nd URL, the updated one. In most cases, timing is everything--and getting a URL crawled and indexed quickly means a lot when it comes to rankings. Keep in mind, though, that you're getting a good ranking, but you then essentially ignore it and get rid of that ranking when you change URLs.

This "card" that you're referring to is actually the Knowledge Graph data that's being displayed. While Wikipedia data is actually a part of the Knowledge Graph, just having a Wikipedia page doesn't mean that it will get a knowledge graph entry shown on the right hand side of the search results.

We have been able to get certain companies and entities their own Knowledge Graph entry previously by adding an entry into Freebase, that option is no longer available. The knowledge graph is, in fact, something that's closely guarded by Google, as there is no place where they list all of the websites that make up the KG, and I believe it changes or is updated regularly.

Based on your example, it is clear Google knows about OIN, but most likely it isn't showing a KG entry because of what it is--an online version of the database published by the U.S. Department of Labor. So, OIN isn't an entity according to Google.

Simon, I'm not sure where you're seeing the duplicates, but generally speaking there are a few ways to deal with this:

• use the robots.txt file to disallow indexing of the duplicate URLs (keep them but disallow from being indexed if they're helpful for users

• remove the PortfolioIDs entirely from the site. If they're not needed and they're not helpful to users then I would remove them entirely.

• set up canonical tags so that even though they're crawled they will still pass on the credit to the main URL.

Typically, the best way to deal with this is to make sure that your subdomain cannot be crawled by the search engines. If Moz crawls it then you will still see the errors. But, if you block Google from crawling it (use the robots.txt file), then you should be fine.

Logan is correct, whenever you use a 301 redirect from one page on your domain to the same domain the link equity is passed (all of it, 100 percent). So, migrating from http to https isn't going to hurt at all. You won't lose any link equity.

I still prefer to updated any links on other sites whenever I can, such as links from social media profiles, etc. and any other links I can get updated.

Typically, website visitors from social media does tend to have a higher bounce rate. But the fact that it's coming from social and those are actually considered links (tweets are links) trumps the fact that they bounce or have a higher bounce rate.

When it comes to bounce rate from a particular source, Google does have info about clicks and bounces from Google's organic search, but I don't believe they have the bounce rate from someone coming from Twitter, clicking on your site, then going back to Twitter. They do have the overall bounce rate data, but apparently they don't use Google Analytics data.

Overall, I don't believe a high bounce rate from social media will have an effect on rankings--it's bounce rate from Google organic search that may have an effect.

When it comes to republishing content, Google is going to look at whether or not the content is duplicate or not. Based on what Google has told us, we know that Google considers something to be duplicate by comparing page to page--not just a headline or an H1 tag.

So, although the headline may be the same, it's quite possible that the content of the page (when looked at as a whole) is not duplicate. There could be other content on the page (usually text) that is shorter or longer than the original page, so there isn't an issue.

But with all duplicate content situations, the first to get crawled is the originator--so it's quite possible that the other site gets crawled first and the actual originator of the content ends up not doing as well in the organic SERPs.

Typically no, LinkedIN decides whether or not the link is nofollow or not. But, if you share the article, and you put the URL in your description, it will be a "do follow" link.

It depends on how many keywords you're wanting to find at a time. You can use the Google Keyword Planner or SEMrush.com that will show related keywords, SEMrush.com will show you a lot at time, and you can download the data into spreadsheets.

Another option would be to use the Google Suggest tool, as you begin typing in Google you'll see related keywords. We also use <cite class="_Rm">https://ubersuggest.io</cite>

Typically the canonical tag should be used when content is duplicate--like when you have the same article appearing on one or more websites. I don't see any reason why you should be using the canonical tag, as those articles are unique.

Since the Google Panda algorithm might come into play here, though, the older articles may eventually hurt your site's search engine rankings if there are too many of them on the site. You might consider creating an archive of your content, perhaps on archive.yourdomain.com and then stopping the search engines from crawling that archive (but still making the article available to readers).

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.

Whatever the case, if you have more than one link to the same page on the same page, only the first one is counted. So, there may be no need for the second link.

What I would do, though, is use Google Analytics' in page analytics to see if you are getting clicks on that second link and which link is getting clicked more often by visitors to that page. If no one clicks on one of the links, you might consider removing it altogether.

As EGOL suggests, if the pages haven't received any traffic in the past year or so, then they most likely are dead weight and  you need to get rid of them. I would, however, do two things:

• Review all the links to your website and 301 redirect any news articles or URLs that have links pointing to them. You'll want to make sure that you keep any links that you have pointing to those pages.

• Rather than use a 404 error on those pages when you remove them, I would use a '410 gone' error to indicate to Google that they're no longer present, have been removed, and they need to remove them from their index.

I tried using it last week and again this week but my location no longer seems to update.

As far as we know, recently Google has changed this feature (turned it off). So, it's very difficult now to use Google to change your location and see results as if you're in another location. Pretty much the only thing you can do now is use a proxy service or VPN to change your location.

Probably the most helpful longtail keyword tool is going to be your own site's analytics and Google AdWords data. You'll see which keywords actually are converting for you, and you can then shift your budget so that you concentrate on those keywords.

Another tool, SEMRush.com is also helpful, as you can actually see what your competitors are bidding on--and see their ad spend, ad copy, etc..

Most of those links are going to be nofollow links, so when it comes to building Domain Authority, it's generally not going to be recognized as a link that passes DA. Google, on the other hand, may actually count those links--as we've seen nofollow links help rankings.

As you build links, keep in mind that it's good to drive real traffic (which helps rankings) and social media shares (which helps rankings) and build your natural link profile (which helps rankings). You need nofollow links for your link profile to be natural.

Chris, we typically recommend that you would identify Google's bot(s) and not serve up the notice to Googlebot. You can certainly also set up a popup (popover) that shows the first time someone visits within a certain period of time--and then not show it on subsequent visits. So Google would get it the first time, and maybe not get it again for another 10 days or 30 days.

Max, for the type of writing project that you're mentioning, we typically look for the writer first--and don't necessarily go with a service. We are looking for someone who is an expert or good writer in a particular subject that fits. For example, we may have a healthcare content need, so we look for healthcare bloggers and contact them directly. This way we end up getting better, more quality content written.

Each location should typically have its own listing. That way you can link directly to the location's page on your website. If you have multiple locations and it's not feasible to manually add them all, there is a way to upload them. I'd say that if you have over a dozen locations then you may consider that--or use a service such as Yext or Moz Local to get them all set up.

Ben, I'm assuming that you have 301 redirects properly set up for all of those page. Then, make sure  you've used the Google Change of Address Tool to properly tell Google that you've moved from one domain to another. If you are consolidating domains, then you need to verify all of those sites in Google Search Console and then use the Change of Address Tool.

You don't mention how long it's been since you've set up those 301 redirects, but it literally can take months before everything is straightened out in Google.

One thing you can also do is to look at the site's log files to see if Google is crawling those pages--it could be that they're not crawling. If they have crawled, then it might just take time before they're indexed.
