AJAX requests and implication for SEO
-
Hi,
I got a question in regard to webpages being served via AJAX request as I couldn't find a definitive answer in regard to an issue we currently face:
When visitors on our site select a facet on a Listing Page, the site doesn't fully reload. As a consequence only certain tags of the content (H1, description,..) are updated, while other tags like canonical URLs, meta noindex,nofollow tag, or the title tag are not updating as long as you don't refresh the page.
We have no information about how this will be crawled and indexed yet but I was wondering if anyone of you knows, how this will impact SEO?

Hi - right, then if the URL changes for the user, you'll want to probably use the PushState method (linked above) to convey this to Google. They likely can't see the URL change by default.
You can check by trying to crawl the site with Screaming Frog SEO Spider with the user agent set to Googlebot. Then go to "outlinks" for the page with the facet links, and see if they are listed.
Hope that helps some more! Let me know if you need further direction.

Hi Dan,
Yes, the URL would change in both cases (AJAX request as well as for a complete refresh).
Thanks

Hi - right, I should have answered your specific situation too

When the user selects a facet - does this change the URL too? Meaning, it's supposed to be a totally different page?

Hi Dan,
Although it doesn't address the specific question I had I think your link is a good start for me to dig into the topic in more detail.
Many Thanks,

Google recently updated how they prefer AJAX is handled:
https://webmasters.googleblog.com/2015/10/deprecating-our-ajax-crawling-scheme.html
They now recommend using the PushState Method - I won't pretend to know all the intricacies of how it works for implementation, but that's the best method to go with. If you need any more help let us know, and I'll have another associate jump in and take a look.

Merging Pages and SEO
Hi, We are redesigning our website the following way: Before: Page A with Content A, Page B with Content B, Page C with Content C, etc
Intermediate & Advanced SEO | | viatrading1
e.g. one page for each Customer Returns, Overstocks, Master Case, etc
Now: Page D with content A + B + C etc.
e.g. one long page containing all Product Conditions, one after the other So we are merging multiples pages into one.
What is the best way to do so, so we don't lose traffic? (or we lose the minimum possible) e.g. should we 301 Redirect A/B/C to D...?
Is it likely that we lose significant traffic with this change? Thank you,0 -
Display:None CSS & SEO
Hi A while back I was told that using the display:none tag to hide content you want minimised is bad for onpage SEO - is this the case? It's not that we want to hide it from Google, we just don't want it taking up a huge amount of space on product pages. I have found some of these on our site, and want to know how bad they are. Is the content under the tag going to be ignored? Thank you

Are dropdown menus bad for SEO
I have an ecommerce shop here: http://m00.biz/UHuGGC I've added a submenu for each major category and subcategory of items for sale. There are over 60 categories on that submenu. I've heard that loading this (and the number of links) before the content is very bad for SEO. Some will place the menu below the content and use absolute positioning to put the menu where it currently is now. It's a bit ridiculous in doing things backwards and wondering if search engines really don't understand. So the question is twofold: (1) Are the links better in a bottom loading sidemenu where they are now? (2) Given the number of links (about 80 in total with all categories and subcategories), is it bad to have the sidemenu show the subcategories which, in this instance, are somewhat important? Should I just go for the drilldown, e.g. show only categories and then show subcategories after? Truth is that users probably would prefer the dropdown with all the categories and second level subcategories, despite the link number and placement.

Web fonts & SEO
Hi everyone ! My question is regarding web fonts. We are currently working on a new design for our website and we're thinking about using web fonts instead of images containing the fonts we'd like to have. I'd like to know if web fonts can affect SEO as they need to be downloaded on the visitor's computers and consequently can slow down the load time of our web pages. If anyone has used web fonts in the past, do you have some specific tips to share ? Thank you in advance for your answers! Jeremie

Subdomains and SEO - Should we redirect to subfolder?
A new client has mainsite.com and a large numer of city specific sub domains i.e. albany.mainsite.com. I think that these subdomains would actually work better as subfolders i.e mainsite.com/albany rather than albany.mainsite.com. The majority of links on the subdomains link to the main site anyway i.e. mainsite.com/contactus rather than albany.mainsite.com/contactus. Having mostly main domain links on a subdomain doesnt seem like clever link architecture to me and maybe even spammy. Im not overly familiar with redirecting subdomains to subfolders. If we go the route of 301'ing subdomains to subfolders any advice/warnings?

Does font size affect SEO?
In the eyes of Google, would the font text size of say a news article affect SEO? For example, a slightly larger font being easier to read by those with bad eyes? Accessibility? If so, what size would be ideal? 10, 12, 14? Your thoughts and suggestions are greatly appreciated.
