Does Page Load Time Affect SEO Rankings?
-
I was curious about how much page load times affect rankings. Here's what I did:
- I put together a lot of interactive media on specific landing pages
- Time-on-Page from organic visitors went from 50 seconds to average of 34 minutes
- Bounce Rate decreased by 20%
- Page Load time increased from 1 second to 6 seconds and at peak times to 8 seconds (on 56KB test)
- In the meantime the page was re-indexed and re-cached
My question is three-fold:
- Would the time on page give higher rankings for keyword
- Would decreased bounce rate enhance rankings?
- Would the page load time decrease rankings?
Did anyone do a similar test? What were the results?

20% is repeat traffic. 80% is new. In past 2 weeks impressions increased around 30-35% and the only thing I can attribute the change to is the interactive stuff.
I have what you may call a niche market. All the competitors out there are focusing on selling products, we're offering a service on top of education. In many cases we're sharing the stuff the product companies would never want clients to know.
But it doesn't hurt to be prepared once other competitors arise, and I'm sure they're coming.
It would be good to find out about the correlation of Time on Page vs. Rankings from others that have tested this.
I'll be sure to post an update in a couple of weeks.

To add to Christy's well written and quite accurate response, page load time has been a key factor since Panda first rolled out. It may have been a factor before this, however Panda is when it first really took hold as a clear, change = results measure. For example, I have had numerous audit clients who had severe page load problems, and several of those have seen increased rankings and resulting traffic from organic listings solely by resolving page load speed.
In one client situation, simply by changing site templates (and resulting load speeds), the client saw a doubling of organic traffic literally overnight. To then test that this was the cause, he then did the same thing with a completely different site that had a completely different model and also saw traffic dramatically increase literally overnight.
However, given the complexity of SEO in 2012, with so many other factors, if there are other serious flaws to the SEO, just increasing page load speeds may not get the same results I've described.
Bounce rates CAN negatively impact rankings, but not purely as a stand-alone factor. It's when someone comes to your site, can't find what they're looking for, then returns to Google and then clicks to another site and does not then come back to Google. Which is also the case even if they didn't initially bounce on first landing on your site. They could also have spent more time, or visited more pages before returning to Google to re-search.

Yes, page load time is a ranking factor. Optimizing pages so they load quickly is listed as a best practice in Google's Webmaster Guidelines. So yes, increased page load load time may decrease rankings. It should definitely decrease traffic. Eight seconds is a looong time these days to wait for a page to load! Have you seen any changes in the SERPs since making these changes?
On the positive side, you must have some fantastic content if users are willing to wait that long for a page to load -- and stay on it for over half an hour I am curious, are you having a lot of repeat traffic?
No, bounce rates do not affect rankings. Matt Cutts has said that if a user visits only one page on a site and finds the information they need, this is a positive user experience. High bounce rates aren't positive for every site, don't get me wrong. If you have an ecommerce site for shoes and you have a very high bounce rate, meaning customers aren't browsing your offerings, writing reviews, and going through checkout, you aren't likely selling very many shoes on the site. The bounce rate is measured in GA to give you the information you need to analyze your site performance in this regard, not for the purpose of ranking your site.
Increased time on page correlates with increased user engagement. Users engage with, and engage longer, with quality content. Or at least highly entertaining content While it is not as clear-cut as to weather this is a ranking factor as is the case for page load time, Google is measuring it and they are all about rewarding websites that provide a great user experience, right?

Google Index Issue - Indexing pages that don't exhist
Hi All, I have noticed a weird issue when performing a search on Google to show me all the pages it is indexing of our site. site:www.one2create.co.uk It brings up most of our website pages but then is also brings up a few HTTPS urls (our site has not been converted to HTTPS yet) but also the URL path, Title, and Meta Description are from one of our clients websites (an Automotive Job site). When clicked they take you to a generic 404 server error page, not our branded 404 page. The site that it has taken the url, title and meta description from is on a different server completely so I don't see how it has even managed to get that information and linked it to our site? Has anyone seen anything like this before? And what is the best way to fix it? We have asked Google to re-index the site but still no luck.

Bounce Rate: Would GA consider a user interacting with a single page (i.e expanding text), before exiting a bounce?
Hey guys, I have done a ton of research regarding bounce rates, yet I cannot seem to find the answer I'm after. Senario: BoIf a user follows a link and lands on a product results page with various sets of filters and an "apply" button, looks through the site, adjusts the filter functions (without changing the url structure) and exists without going to another page - would that qualify as a bounce in Google Analytics? For example: If I click 'details' to see expandable text on a results page ( /credit-cards). The dynamic url I'm talking about is below: https://masii.co.th/thai-en/credit-card/compare-buy?category=shopping%2Ccashback%2Cair_miles%2Cassistance%2Cdining%2Cpetrol%2Crewards&income=30000

Higher rankings, low traffic
Hello There, My question is the following: How come my rankings are much higher than when I started with the optimization process (1 year ago) but my organic traffic is lower compared to the previous year (it didn't increase at all)? NB - I haven’t received any penalization and the keywords I am targeting are definitively searched and are the most important for my company. Thanks a lot 🙂

Has anyone found a best practice for ranking a client who has one central office location, but a large, regional service area that they want to rank for?
All the most recent local search ranking is based upon physical addresses, but what happens when someone provides services and has staff 100 miles from that central office location, but no physical address to work with?

All pages were returning 404 for an hour. Will it impact the SERPS?
Hi, Due to a bug in my website system, all the pages were returning an 404 default page for a period of 1 hour. Can this event impact the SERPs of this site? (the site is heavily visited, more than 500k users coming from google every day, so I assume google crawls my pages every moment)

Why are Google ranking changes so drastic?
Hi SEOmoz community I'm sure this question has been asked numerous times before. At the same time there must be plenty of people out there wondering about the same thing: Why are Google ranking changes so drastic? It's like the diva of search engines. When checking the SEOmoz ranking reports, sometimes lots of keywords improve, the next week it's vice versa. Mind though that the ranking changes are not in proportion. While improving keywords climb up by approx. 1 - 10 positions, declining keywords always get a smack with a 15 - 25 position drop, even though these very same keywords are being targeted onsite through new content. It seems to make no difference after all 😉 Is it possible, that keyword fluctuations are stronger for younger sites? The site I am talking about is about a year old. Is it possible that more competitive keywords see more drastic fluctuations? Would be interested to hear your thoughts. Thanks!!

Will creating sub folders for foreign versions of the website, remove rank juice from the main site?
Hi, We plan to create sub-folders for our german, spanish and italian language versions. If we do will this pass rank juice to the new sites, but at the same time badly effect our main site, regards link juice/serp? Or is this not such a huge factor in people's experience? Many thanks. James.
