Does a CDN affect search rankings?
-
I feel kind of stupid asking this, but if i use one it would speed things up quite a bit. It is for a ecommerce website, any guidance on this would be awesome!
-
Google officially said the site speed is a SEO factor which, when implemented, will affect 1% of SERP results. This gives some idea of the scope of it's relevancy. (not saying 1% is either high or low, this is all very subjective)
Having said that, beyond speed improvement, CDN provides other SEO related benefits.
I've actually just published a 2-part Blog post that investigates SEO & CDN related myths and talks about CDN and SEO benefits, I hope you`ll find it useful. it should answer all questions:
Part 1: SEO & CDN Myths
Part 2: SEO & CDN benefits -
I use a CDN and have never seen any impact on my SEO. As long as your HTML is served off your domain you're fine.
If you're using AWS Cloudfront you can set up a CNAME so that your content comes from, say, images.mydomain.com instead of xyz.cdn.com. Helps obscure it from visitors and looks a bit neater.
-
Using a properly configured CDN will not have any negative effects on SEO. It can have positive effects on your rankings by offering faster page loads.
With Google's current system, you would not see a SEO benefit per se. If your current site is deemed slow by Google, you could have your current speed penalty lifted.
Moving to a CDN will surely provide a better user experience. Google is constantly adjusting it's algorithms in chase of the best user experience, so this is a chance for you to get ahead of the game. It is reasonable to think in the future Google may consider site speed as a ranking factor.
Two other suggestions regarding setting up a CDN:
-
you need to be very conscious of your cache settings. You could make a change on your site and users will not see the change if you do not ensure that change is propagated throughout your CDN
-
try to include all files which would benefit from a CDN. I have seen some sites just add their videos and image files to the CDN. Custom Javascript, CSS files and so forth can all benefit from CDN. PageSpeed and YSlow are two great tools for optimizing page loading times.
-
-
As far as I know, the urls of your additional resources such as images, css, and scripts shouldn't affect your SEO either way.
-
But, does the use of a Content Delivery Network (cdn) itself affect seo? For example my pics / code will be hosted differently. Just kind of confusing to me since I'm used to URL structure being: mydomain.com/images/pic.jpg instead of xyz.cdn.com/2523/myname/pic.jpg. Is this even something to be concerned about?
-
Site speed is only relevant when your site is extremely slow. Google doesn't penalize you unless your page load time is excessively long. You won't get a boost in rankings by speeding up your site.
With that in mind, Site load times do affect your user experience, so you may notice a lower bounce rate, more pages per visit, and possibly a higher conversion rate.

Hi, I was inspecting a website which is covering the topic of best wheelbarrow of 2021, it is a new website and and starts ranking on google. But, after few days it got de-rank automatically and Moz is also not showing any result to that.

Does this parameter change page content seen by the user? - Yes, Changes, reorders, or narrows page content.
How does this parameter affect page content? - Narrow

Now I am doing tracking of filter pages via data layer and tag manager so in google analytic I am not able to see filter url's because of this parameter. So I want to delete this parameter.

Does an Apostrophe affect searches?
Does Google differentiate between keyphrase structures such as Mens Sunglasses & Men**'**s Sunglasses? I.e. does the inclusion/exclusion of an apostrophe make any difference when optimising your main keyword/phrase for a page? Keyword explorer appears to give different results..... I.e. no data for Men's Sunglasses, but data appears for Mens sunglasses. So if I optimise my page to include the apostrophe, will it screw the potential success for that page? Thanks 🙂 Bob

Google truncating or altering meta title - affect rankings?
I have a site that the title tag is too long and the title is simply the name of the site (I think they get it from ODP, not sure) Anyway, the rankings for the home page have dropped quite a bit. I'm wondering if the change that Google makes affects rankings (i.e. name of site doesn't have all the keywords).

How to Resolve Rankings Drop from a DDOS Attack?
Our rankings just plummeted on Tuesday across the board. There was a DDOS attack on Tuesday and since then the rankings went down and have stayed down, even though the DDOS attack has been resolved. Also, this is the 3rd or 4th attack they've encountered this year. How long could this last? How can we deal with this? Thanks

Sudden ranking drop, no manual action
Sort of a strange situation I'm having and I wanted to see if I could get some thoughts. Here's what has happened... Monday morning, I realized that my website, which had been showing up at the bottom of page 2 for a specific result, had now been demoted to the bottom of page 6 (roughly a 40 spot demotion). No other keyword searches were affected. I immediately figured that this was some sort of keyword-specific penalty that I had incurred. I had done a bit of link building over the weekend (two or three directory type sites and a bio link from a site I contribute to). I also changed some anchor text on another site to match my homepage's title tag (which just so happened to be the exact phrase match I had dropped in) - I assumed this was what got me. I was slowly beginning to climb up the rankings and just got a bit impatient/overzealous. Changed the anchor text back to what it originally was and submitted a reconsideration request on Tuesday. This morning, I get the automated response in Webmaster Tools that no manual action had been taken. So my question is, would this drop have been an automated deal? If that's the case, then it's going to be mighty hard to pinpoint what I did wrong, since there's no way to know when I did whatever it was to cause the drop. Any ideas/thoughts/suggestions to regain my modest original placement?

Subdomain and Domain Rankings
I have read here that domain names with keywords might add a boost to your search rank For instance using a completely inane example monkey-fights.com might get a boost compared to mfl.com (monkey fighting league) when searching for "monkey fights" There seems to be a hot debate as to how much bonus the first domain might get over the second, but leaving that aside for the moment. Question 1. Would monkey-fights.mfl.com get the same kind of bonus as a root domain bonus? Question 2. If the answer to 1 above was yes would a 301 redirect from the suddomain URL to root domain URL retain that bonus I was just thinking on how hard it is to get root domains these days that are not either being squatted on etc. and if this might be a way to get the same bonus, or maybe subdomains are less bonus prone and so it would be a waste of time Thanks
