Deferred javascript loading
-
Hi! This follows on from my last question.
I'm trying to improve the page load speed for http://www.gear-zone.co.uk/.
Currently, Google rate the page speed of the GZ site at 91/100 – with the javascript being the only place where points are being deducated. The only problem is, the JS relates to the trustpilot widget, and social links at the bottom of the page – neither of which work when they are deferred.
Normally, we would add the defer attribute to the script tags, but by doing so it waits until the page is fully loaded before executing the scripts. As both the js I mentioned (reviews and buttons) use the document.Write command, adding this would write the code off the page and out of placement from where they should be.
Anyone have any ideas?

Ive run your site through the Page Speed tool here and you get 94/100 (which is awesome!).
No idea on the JS sorry
I'd be more than happy with 94/100!

Load Balancer issues on Search Console
The top linked domains in search console are coming from our load balancer setup. Does anyone know how to remove these as unique sites pointing back to our primary domain? I was told Google is smart enough to ignore these as duplicate domains but if that was the case, why would they be listed as the top linked domains in search console? Most concerned....

Lazy Load Pictures on main page
Hello, our website is https://www.neakriti.gr If you open our page you will see its fast (for its size - we use AKAMAI and caching), but we have a large number of pictures on the main page - that inevitably cost loading time. I believe there could be a dramatic reduction in the time taken to load the pictures if we implemented a lazy load approach for the "below" the fold" content. Would a lazy load approach increase our SEO score on our main page? If yes, how should it be implemented in SEO terms? (I mean so that search engines are able to find the pictures that are not loaded beforehand).

Lazy Loading of products on an E-Commerce Website - Options Needed
Hi Moz Fans. We are in the process of re-designing our product pages and we need to improve the page load speed. Our developers have suggested that we load the associated products on the page using Lazy Loading, While I understand this will certainly have a positive impact on the page load speed I am concerned on the SEO impact. We can have upwards of 50 associated products on a page so need a solution. So far I have found the following solution online which uses Lazy Loading and Escaped Fragments - The concern here is from serving an alternate version to search engines. The solution was developed by Google not only for lazy loading, but for indexing AJAX contents in general.
Intermediate & Advanced SEO | | JBGlobalSEO
Here's the official page: Making AJAX Applications Crawlable. The documentation is simple and clear, but in a few words the solution is to use slightly modified URL fragments.
A fragment is the last part of the URL, prefixed by #. Fragments are not propagated to the server, they are used only on the client side to tell the browser to show something, usually to move to a in-page bookmark.
If instead of using # as the prefix, you use #!, this instructs Google to ask the server for a special version of your page using an ugly URL. When the server receives this ugly request, it's your responsibility to send back a static version of the page that renders an HTML snapshot (the not indexed image in our case). It seems complicated but it is not, let's use our gallery as an example. Every gallery thumbnail has to have an hyperlink like: http://www.idea-r.it/...#!blogimage=<image-number></image-number> When the crawler will find this markup will change it to
http://www.idea-r.it/...?_escaped_fragment_=blogimage=<image-number></image-number> Let's take a look at what you have to answer on the server side to provide a valid HTML snapshot.
My implementation uses ASP.NET, but any server technology will be good. var fragment = Request.QueryString[``"_escaped_fragment_"``];``if (!String.IsNullOrEmpty(fragment))``{``var escapedParams = fragment.Split(``new``[] { ``'=' });``if (escapedParams.Length == 2)``{``var imageToDisplay = escapedParams[1];``// Render the page with the gallery showing ``// the requested image (statically!)``...``}``} What's rendered is an HTML snapshot, that is a static version of the gallery already positioned on the requested image (server side).
To make it perfect we have to give the user a chance to bookmark the current gallery image.
90% comes for free, we have only to parse the fragment on the client side and show the requested image if (window.location.hash)``{``// NOTE: remove initial #``var fragmentParams = window.location.hash.substring(1).split(``'='``);``var imageToDisplay = fragmentParams[1]``// Render the page with the gallery showing the requested image (dynamically!)``...``} The other option would be to look at a recommendation engine to show a small selection of related products instead. This would cut the total number of related products down. The concern with this one is we are removing a massive chunk of content from he existing pages, Some is not the most relevant but its content. Any advice and discussion welcome 🙂0 -
Can you explain why a site with loads of keywork anchor backlinks is ranking well?
Hi All, A couple of years ago my site got punished and i kind of figured out it was due to keyword anchor text backlinks. I recently was considering getting a new SEO company and found one that promotes another company in my industry. However, when i look at the backlinks, of the website they do SEO for, via open site explorer - I noticed nearly all of the backlinks are keywords. website in question is http://goo.gl/6nRzLi And if you see the search results here: http://goo.gl/9bXoxY they are ranking on first page with very big brands - and have done for about a year - but nealy all of their backlinks are the keywords in this search... I understood this is the kind of thing that killed my website 2 years ago - are these backlinks ok? should i still consider this SEO company to work on my site, i 100% do not want my site to be penalised again so any advice appreciated. thanks James

Javascript to fetch page title for every webpage, is it good?
We have a zend framework that is complex to program if you ask me, and since we have 20k+ pages that we need to get proper titles to and meta descriptions, i need to ask if we use Javascript to handle page titles (basically the previously programming team had NOT set page titles at all) and i need to get proper page titles from a h1 tag within the page. current course of action which we can easily implement is fetch page title from that h1 tag being used throughout all pages with the help of javascript, But this does makes it difficult for engines to actually read what's the page title? since its being fetched with javascript code that we have put in, though i had doubts, is anyone one of you have simiilar situation before? if yes i need some help! Update: I tried the JavaScript way and here is what it looks like http://islamicencyclopedia.org/public/index/hadith/id/1/book_id/106 i know the fact that google won't read JavaScript like the way we have done with the website, But i need help on "How we can work around this issue" Knowing we don't have other options.

Google, Links and Javascript
So today I was taking a look at http://www.seomoz.org/top500 page and saw that the AddThis page is currently at the position 19. I think the main reason for that is because their plugin create, through javascript, linkbacks to their page where their share buttons reside. So any page with AddThis installed would easily have 4/5 linbacks to their site, creating that huge amount of linkbacks they have. Ok, that pretty much shows that Google doesn´t care if the link is created in the HTML (on the backend) or through Javascript (frontend). But heres the catch. If someones create a free plugin for wordpress/drupal or any other huge cms platform out there with a feature that linkbacks to the page of the creator of the plugin (thats pretty common, I know) but instead of inserting the link in the plugin source code they put it somewhere else, wich then is loaded with a javascript code (exactly how AddThis works). This would allow the owner of the plugin to change the link showed at anytime he wants. The main reason for that would be, dont know, an URL address update for his blog or businness or something. However that could easily be used to link to whatever tha hell the owner of the plugin wants to. What your thoughts about this, I think this could be easily classified as White or Black hat depending on what the owners do. However, would google think the same way about it?
