    Hi Moz Fans,

    We are looking at our blog and improving the content as much as we can for SEO purposes, but we have hit a bit of a blank in terms of lazy loading implications and issues with crawl depths.

    We introduced lazy loading onto the blog home page to increase site speed initially and it works well with infinite scroll, but we were wondering whether this would cause any issues regarding SEO.

    A lot of the resources online seem to be conflicting and some are very outdated, so some clarification on what is best in terms of lazy loading and crawl depths for blogs, would be fantastic!

    I hope someone can help and give us some up to date insights - If you need anymore information, I'll reply ASAP

        Lazy load and infinite scroll are absolutely not the same thing, as far as search crawlers are concerned.

        Lazy-loaded content, if it exists in the dom of the page will be indexed but it's importance will likely be reduced (any content that requires user interaction to see is reduced in ranking value).

        But because infinite scroll is unmanageable for the crawler (it's not going to stay on one page and keep crawling for hours as every blog post rolls into view) Google's John Mueller has said the crawler will simply stop at the bottom of the initial page load.

        This webinar/discussion on crawl and rendering from just last week included G's John Mueller and a Google engineer and will give you exactly the info you're looking for, right from the horse's mouth, Victoria.

        To consider though - the blog's index page shouldn't be the primary source for the blog's content anyway - the individual permalinked post URLs are what should be crawled and ranking for the individual post content. And the xml sitemap should be the primary source for google's discovery of those URLs. Though obviously linking from authoritative pages will help the posts, but that's going to change every time the blog index page updates anyway. Also, did you know that you can submit the blog's RSS feed as a sitemap in addition to the xml sitemap? It's the fastest way I've found of getting new blog posts crawled/indexed.

        Hope that helps!

        Paul

          I'm afraid I don't have an insight into how Google crawls with lazy loading.

          Which works better for your user, pagination or lazy loading? I wouldn't worry about lazy loading and Google. If you're worried about getting pages indexed then I would make sure you've got a sitemap that works correctly.

            Great, thank you

            Do you have any insight into crawl depth too?
            At what point would Google stop crawling the page with lazy loading? Is it best to use pagination as opposed to infinite scroll?

              With lazy loading, the code can actually still be seen in the source code. That's what Google uses, so you should be fine with using this as it's becoming a common practice now.

                Yes, it's similar to the BBC page and loads when it is needed by the user so to speak.

                It increased the site loading, but do you know at what point Google would stop indexing the content on our site?

                How do we ensure that the posts are being crawled and is pagination the best way to go?

                  I'd have to say, not too familiar with the method you are using, but I take it the idea is elements of the page load as you scroll like BBC?

                  If it decreases the load time of the site that is good for both direct and indirect SEO, But the key thing is can Google see the contents of the page or not? - Use Google Search Console and fetch the page to see if it contains the content.

                  Also, Google will not hang around on your site, if it doesn't serve the content within a reasonable amount of time it will  bounce off to the next page, or the next site to crawl.  It's harsh, but it's a fact.

                    Topical keywords for product pages and blogs

                    Hi all, I have a question regarding keywords. Of course we all know that keyword research should be focused on a certain topic and on user intent (and thus on answering specific questions) instead of trying to put keywords in a page to make it rank. However, duplicate content is of course still an issue. So here's my question: A client that sells floor heating systems that you can install yourself, has a product page for this topic and blog pages for questions regarding this topic. So following pages are on the website: Product page about the floor heating systems the client sells Blog article with tips how to install a floor heating system yourself Blog article about how to choose the right floor heating system These pages all answer different questions and are written about different topics. However, inevatibly all these pages also talk about different aspects of floor heating systems so this broad term comes up on all pages naturally. You could say that a solution is to merge pages and redirect the blogs to the product page, so the product page would answer all questions. But that is not what a customer is looking for. The goal of a product page is to trigger a conversion: let a customer contact the company or ask for a price offer. If the content on a product page is not comprehensive enough, the goal gets lost. Moreover, it doesn't make sense to talk about tips and tricks on a product page. So how do you tackle this problem without creating duplicate content? In search results, the blog pages rank for the specific questions, but the product page doesn't rank for the generic term 'floor heating'. The internal link structure is ok: the product page has obviously more incoming links than the blogs. All on page SEO factors are taken care of as well. Any ideas on this? Thanks!

                    Pagination loading with using AJAX. Should I change this?

                    Hello, while I was checking this site; http://www.disfracessimon.com/disfraces-adultos-16.html I found that the pagination is working this way http://www.disfracessimon.com/disfraces-adultos-16.html#/page-2
                    http://www.disfracessimon.com/disfraces-adultos-16.html#/page-3 and content is being loaded using AJAX. So, google is not getting the paginated results. Is this a big issue or there is no problem?
                    Should I create a link for See All Products or there is not a big issue? Thank you!

                    Blog subdomain not redirecting

                    Over the last few weeks I have been focused on fixing high and medium priority issues, as reported by the Moz crawler, after a recent transition to WordPress. I've made great progress, getting the high priority issues down from several hundred (various reasons, but many duplicates for things like non-www and www versions) to just five last week. And then there's this weeks report. For reasons I can't fathom, I am suddenly getting hundreds of duplicate content pages of the form http://blog.<domain>.com</domain> (being duplicates with the http://www.<domain>.com</domain> versions). I'm really unclear on why these suddenly appeared. I host my own WordPress site ie WordPress.org stuff. In Options / General everything refers to http://www.<domain>.com</domain> and has done for a number of weeks. I have no idea why the blog versions of the pages have suddenly appeared. FWIW, the non-www version of my pages still redirect to the www version, as I would expect. I'm obviously pretty concerned by this so any pointers greatly appreciated. Thanks. Mark

                    Would you rate-control Googlebot? How much crawling is too much crawling?

                    One of our sites is very large - over 500M pages.   Google has indexed 1/8th of the site - and they tend to crawl between 800k and 1M pages per day. A few times a year, Google will significantly increase their crawl rate - overnight hitting 2M pages per day or more.  This creates big problems for us, because at 1M pages per day Google is consuming 70% of our API capacity, and the API overall is at 90% capacity.   At 2M pages per day, 20% of our page requests are 500 errors. I've lobbied for an investment / overhaul of the API configuration to allow for more Google  bandwidth without compromising user experience.   My tech team counters that it's a wasted investment - as Google will crawl to our capacity whatever that capacity is. Questions to Enterprise SEOs: *Is there any validity to the tech team's claim?  I thought Google's crawl rate was based on a combination of PageRank and the frequency of page updates.   This indicates there is some upper limit - which we perhaps haven't reached - but which would stabilize once reached. *We've asked Google to rate-limit our crawl rate in the past.   Is that harmful?  I've always looked at a robust crawl rate as a good problem to have. Is 1.5M Googlebot API calls a day desirable, or something any reasonable Enterprise SEO would seek to throttle back? *What about setting a longer refresh rate in the sitemaps?   Would that reduce the daily crawl demand?  We could set increase it to a month, but at 500M pages Google could still have a ball at the 2M pages/day rate. Thanks

                    Blog comments - backlinks - question

                    Hi, I see that many good websites have backlinks from very good blogs/sites which are relative. What I noticed that everyone use their real name or generic name in comments. They do not use the keyword for the name. So later they get backlinks with anchor text of their names... So, my question is this good technique ? Do I have any benefits from these backlinks for my website ? With such a technique, whether it is enough just to leave your real name or may I periodically put the keyword for the name ? Thank you

                    How is Google crawling and indexing this directory listing?

                    We have three Directory Listing pages that are being indexed by Google: http://www.ccisolutions.com/StoreFront/jsp/ http://www.ccisolutions.com/StoreFront/jsp/html/ http://www.ccisolutions.com/StoreFront/jsp/pdf/ How and why is Googlebot crawling and indexing these pages? Nothing else links to them (although the /jsp.html/ and /jsp/pdf/ both link back to /jsp/). They aren't disallowed in our robots.txt file and I understand that this could be why. If we add them to our robots.txt file and disallow, will this prevent Googlebot from crawling and indexing those Directory Listing pages without prohibiting them from crawling and indexing the content that resides there which is used to populate pages on our site? Having these pages indexed in Google is causing a myriad of issues, not the least of which is duplicate content. For example, this file <tt>CCI-SALES-STAFF.HTML</tt> (which appears on this Directory Listing referenced above - http://www.ccisolutions.com/StoreFront/jsp/html/) clicks through to this Web page: http://www.ccisolutions.com/StoreFront/jsp/html/CCI-SALES-STAFF.HTML This page is indexed in Google and we don't want it to be. But so is the actual page where we intended the content contained in that file to display: http://www.ccisolutions.com/StoreFront/category/meet-our-sales-staff As you can see, this results in duplicate content problems. Is there a way to disallow Googlebot from crawling that Directory Listing page, and, provided that we have this URL in our sitemap: http://www.ccisolutions.com/StoreFront/category/meet-our-sales-staff, solve the duplicate content issue as a result? For example: Disallow: /StoreFront/jsp/ Disallow: /StoreFront/jsp/html/ Disallow: /StoreFront/jsp/pdf/ Can we do this without risking blocking Googlebot from content we do want crawled and indexed? Many thanks in advance for any and all help on this one!

                    Best way to block a search engine from crawling a link?

                    If we have one page on our site that is is only linked to by one other page, what is the best way to block crawler access to that page? I know we could set the link to "nofollow" and that would prevent the crawler from passing any authority, and we can set the page to "noindex" to prevent it from appearing in search results, but what is the best way to prevent the crawler from accessing that one link?

                    Should I Allow Blog Tag Pages to be Indexed?

                    I have a wordpress blog with settings currently set so that Google does not index tag pages. Is this a best practice that avoids duplicate content or am I hurting the site by taking eligible pages out of the index?
