How To Implement Pagination Properly? Important and Urgent!
-
I have seen many instructions but I am still uncertain. Here is the situation
We will be implementing rel prev rel next on our paginted pages.
The question is:
- Do we implement self referencing canonical URL on the main page and each paginated page?
- Do we implement noindex/follow meta robots tag on each paginated page?
- Do we include the canonical URL for each paginated page in the sitemap if we do not add the meta robots tag?
- We have a view all but will not be using it due to page load capabilities...what do we do with the viewl all URL? Do we add meta robots to it?
- For website search results pages containing pagination should we just put a noindex/follow meta robots tag on them?
- We have seperate mobile URL's that also contain pagination. Do we need to consider these pages as a seperate pagination project? We already canonical all the mobile URL's to the main page of the desktop URL.
Thanks!

Hello SEO32,
I apologize for the delayed response. There are several good questions here. They're also complicated questions, which don't really always have a single "correct" answer. So much revolves around the specific situation, and without seeing your website it is difficult to say what is best for you. Also, much of what we think we know about this kind of stuff is either based on what Google tells us (which isn't always the truth) and what we've observed and deduced from our own experiences (which aren't always the same). True "testing" of this stuff one variable at a time isn't always possible so we rely on best practices and our own experience.
That said, I will attempt to answer your questions with what I would probably do in most situations, including links to more information when possible.
Do we implement self referencing canonical URL on the main page and each paginated page?
Here's what Rand says, and he's probably seen way more data than I have:
"Whatever you do, DO NOT:
- Put a rel=canonical directive on paginated results pointing back to the top page in an attempt to flow link juice to that URL. You'll either misdirect the engines into thinking you have only a single page of results or convince them that your directives aren't worth following (as they find clearly unique content on those pages).
- Add nofollow to the paginated links on the results pages. This tells the engines not to flow link juice/votes/authority down into the results pages that desperately need those votes to help them get indexed and pass value to the deeper pages.
- Create a conditional redirect so that when search engines request paginated results, they 301 redirect or meta refresh back to the top page of results."
Keep in mind that post is from 2010, and I think before Google said a "View All" canonical <a>was their preference</a>.
I have seen plenty of sites do well ranking the canonical category page, and with indexing most of the product pages, while all paginated pages had a rel canonical that referenced the first page in the series (i.e. .com/category/ or .com/categry1/category2/). It probably helps that they had good XML sitemaps for product pages, and plenty of internal linking, unique content on category pages, etc.
I have also seen sites do well using rel next/prev without rel canonical, or rel next/prev with self-referencing canonicals on paginated category pages.
I think where you run into problems is when you also allow the facet/filter/sort versions to have self-referencing rel canonical tags.
Here is what I advise in most cases:
Use rel next/prev (not because I think it works, but because Google says to and I don't think it hurts) along with self-referencing rel canonical tags, and "follow,noindex" robots meta tags on paginated pages.
Always include a followable link to the first page in the series from every subsequent page. For example:
<previous>first...1...25...26...27...last...</previous>
I recommend always having a first and last page link. The first is obvious because it means pagerank is going to flow into it from every other page in the set, giving it the most internal links of all. The last is more of a crawlability and usability thing. For users it helps us figure out how much further we have to go. It does the same thing for search engines. Instead of blindly following a path that may or may not have an end, a message is sent that tells a spider how much further it has to go. I don't know if Google takes advantage of that signal or not, but it just makes sense to include it. If you want to get fancy you can try making the 'last' link flash or javascript or something so it doesn't pass (as much?) page rank.
The category root pages usually have links from site-wide navigation, unlike the paginated versions, which further establishes it as the page that should be ranked highest.
Make sure the first page in each series is indexable, and has content that does not appear on the paginated versions. Also, make sure that ?p=1 doesn't have a self-referencing canonical tag, but references the root page for that series (e.g. /category1/category2/).
All subsequent variations (e.g. color, size) should rel canonical back to their root page. For example:
/category1/category2/?page=2&size=s&color=blue would have the following URL in the rel canonical tag:
/category1/category2/?page=2
Which happens to be followable, but not-indexable, and has a self-referencing rel canonical tag.In this way you give search engines a strong signal about which URL in the whole set is the strongest (i.e. /category1/category2/) because it is indexable, has its own content, has the most internal and external links, is the simplest version of this URL pattern, and is at the root of the directory. You're telling search engines which page is next in the series, and that this page is first in the series. You're telling search engines which page is last in the series, as well. Google usually does an awesome job figuring it out from there. There are always exceptions.
Do we implement noindex/follow meta robots tag on each paginated page?
I would. Consider this from Google's perspective, or from that of a searcher. Someone types "Blue Flower Dress" into Google. Is the best page to return a deep category page full of blue dresses, one of which happens to have flowers? Or would it be the Blue Flower Dress product page? I can't think of any reason why I would want to land on page 3, where what I'm looking for is listed among dozens of other things, when I could just go straight to the thing I'm looking for.
Likewise, if someone searches for "Blue Dresses" is the best page /dresses/blue/?page=3 (paginated page in the Blue Dresses category), OR /dresses/blue/ (the very first page of the Blue Dresses category), which also has useful content about blue dresses?
Long story short, when it comes to transactional eCommerce queries, they're usually either looking for a product page or the first page of a specific category or sub-category. Or sometimes the home page. Therefore, I don't see any reason for allowing paginated URLs to be indexable in most cases. Non-transactional eCommerce content is different (e.g. buying guides, comparison charts, reviews...) but I still wouldn't allow paginated pages to be indexed in most cases.
Slightly Off Topic - Filters/Facets/Sorts
Or perhaps the category is "casual dresses" and "blue" is specified in the "color" attribute. In this case, would the best page be /dresses/casual/?color=blue , /dresses/casual/ or /dresses/casual/?color=blue&page=4 for someone who Googled "blue dresses"? I've bolded the one I'd prefer as a searcher.
Here again, as with the internal search results, there is an opportunity to use real data to inform your decision. Pay attention to the facet/filter/sort URLs most accessed by shoppers and consider turning those into category or collections pages with their own URL pattern (e.g. /dresses/casual/blue/). One example I come across all the time is when "Brand" is a filter instead of its own limb in the category structure. If people are shopping by brand, as they do with most consumer products, then you should have a brand subcategory under each major top-level category. If I search for Levi Jeans Google doesn't want to send me to a "pants" page where I have to set a filter to see only Levis. I should go to pants/brand/levi/ . If I Google Chefmate Pots I want to see cookware/pots/brands/chefmate so I don't have to set a filter after I get there.
This doesn't mean all filter pages should be turned into category pages either. Use your best judgement based on the pages most of your users are accessing from the navigation and filters.
Do we include the canonical URL for each paginated page in the sitemap if we do not add the meta robots tag?
I would add the robots meta tag. Please let me know if I've misunderstood the question.
We have a view all but will not be using it due to page load capabilities...what do we do with the view-all URL? Do we add meta robots to it?
I would add a meta robots "index,nofollow" tag, and would also use the canonical page's URL (e.g. /category1/category2) in the rel canonical tag.
For website search results pages containing pagination should we just put a noindex/follow meta robots tag on them?
This is one of those situations involving crawl budget potentially being eaten up by an infinite amount of pages. I would consider blocking the internal search result URLs in the robots.txt file. They are of no use to Google, as they consider a search engine returning search results with links to more search results somewhere else a bad user experience. This is also what Google recommends in their Webmaster Guidelines:
"Use robots.txt to prevent crawling of search results pages or other auto-generated pages that don't add much value for users coming from search engines."
However, I would also make use of those pages internally. Rather than relying on a search result page for things people often look for, track what is being searched for and create static, indexable pages. For example, try "Collections" pages on eCommerce sites, as well as FAQ pages, or "Industries" or "Use Case"-type pages on lead generation sites. This is a much better user experience for someone arriving on that page from a search engine.
We have separate mobile URL's that also contain pagination. Do we need to consider these pages as a separate pagination project? We already canonical all the mobile URL's to the main page of the desktop URL.
I think you should if that's the way you're handling it. Here is a post I did on mobile best practices. It covers some other options. I would also add a rel=”alternate” tag in the HTML header of the desktop page, which alerts search engines to the corresponding mobile URL and helps define the relationship between the two pages.
The bottom line for me is to always think about what would be the best experience for someone searching from Google for something, and to try and use all of the various technical options to ensure that is the page I'm telling Google they should rank for that query, or those types of queries. The 'best practice' changes, depending on the situation.
I hope others will join the discussion with their own experiences and findings.

Homepage keeps disappearing and reappearing for important keywords every few days
My homepage keeps disappearing from the SERPS for my most important keywords. My home page has been in number 2 position for years. When the home page disappears it will not even show in a Google search for my business name although it is still indexed. When the home page is not showing an internal page shows instead but in position 6. When the home page is back the internal page does not show. There are no issues being reported in Google Webmaster. When I realise that it's down I do a fetch as Google and request reindexing. No idea if this is bringing it back or not? We are so worried about this and totally at a loss. As are the three SEO companies I've called. Would really appreciate it if someone could give some advice. NSFW https://goo.gl/dwA8YB

Importance of City in Title?
Anyone doing SEO for a local business ever tried to do an A/B test between city name in title and not in title? Seems that if you have a Google Places for Business Listing and have correct NAP on your web pages, Google places heavy importance already on that when determining geographic relevance in their algo. As a business expands, maybe not that far from their original service area but starts to offer services in other nearby cities some of which may be as big of a population as the city the business is located in, it seems to make less and less sense to put city names in the title if not for the basic reason of making the title too long. But what if your primary area is basically three cities and including them pushed your title to say, 90 characters. How much does city name in the title tag matter when you are already coming up the local 3-pack map listing on search results for the relevant cities?

How important is the user experience for SEO in google's eyes?
So far I've gathered that backlinks are really king, however you can't get good backlinks without well written content that serves a purpose. As well you can't do a great job with that content and not keep a good user experience, since why would anyone want to backlink to content that can be helpful if you squint an eye and suffer a few scrolling cramps. So how would you rank user experience in the everlasting war of SEO for Google? With this in mind, why would using bootstrap resources pose a problem? I've seen it could add issue to pageload times, however seems minifying could easily solve that. I personally enjoy the use of Bootstrap since it's very easy on the eyes and can have real positive effects when a user looks at content on such a framework.

Rel=Alternate on Paginated Pages
I've a question about setting up the rel=alternate & rel=canonical tags between desktop and a dedicated mobile site in specific regards to paginated pages. On the desktop and mobile site, all paginated pages have the rel=canonical set towards a single URL as per usual. On the desktop site though, should the rel=alternate be to the relevant paginated page on the mobile site (ie a different rel=alternate on every paginated page) or to a single URL just as it is vice versa. Cheers chaps.

We're currently not using schemas on our website. How important is it? And are websites across the globe using it?
Schemas looks like an important thing when it comes to structuring your website and ensuring the crawl bots get all the details. I've been reading a lot of articles around the web and most of them are saying that schemas are important but very few websites are using it. Why so? Are the schemas on schema.org there to stay or am I wasting my time?

Best way to implement canonical tags on an ecommerce site with many filter options?
What would be the best way to add canonical tags to an ecommerce site with many filter options, for example, http://teacherexpress.scholastic.com? Should I include a canonical tag for all filter options under a category even though the pages don't have the same content? Thanks for reading!

Duplicate title tags in a pagination case (not search results)
Hello fellows I working on a site that have duplicate pages' titles tags, the case is the following: there is a category page that is split in couple pages via pagination (1,2,3 ....) all these pages have the same title tag for example: looking at this page for example, it has a pagination at the bottom, all the pages in the pagination (let's say page 5 for example) have the same title tag for the rest (including the first page). How should I deal with this case? should I simply add to the title tag its corresponding page number? e.g, full interviews - page 1? or I should I use canonical tag? I'm really confused. Your help is really appreciated.

Pagination and links per page issue.
Hi all, I have a listings based website that just doesn't seem to want to pass rank to the inner pages. See here for an example: http://www.business4sale.co.uk/Buy/Hotels-For-Sale-in-the-UK I know that there are far too many links on this page and I am working on reducing the number by altering my grid classes to output fewer links. The page also displays a number of links to other page numbers for these results. My script adds the string " - Page2" to the end of the title, description and URL when the user clicks on page two of these results. My question is: Would an excessive amount(200+) of links on a page result in less PR being passed to this page(looking spammy)? And would using rel canonical on page numbers greater than 1 result in better trust/ranking? Thanks in advance.
