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!

Can Google Crawl & Index my Schema in CSR JavaScript
We currently only have one option for implementing our Schema. It is populated in the JSON which is rendered by JavaScript on the CLIENT side. I've heard tons of mixed reviews about if this will work or not. So, does anyone know for sure if this will or will not work. Also, how can I build a test to see if it does or does not work?

Does google credit links from iFrames or created by Javascript, if so, is one more powerful than the other?
Consider this example, because I want to be clear about what I mean. You have two websites. Lets all them www.a.com and www.b.com. On www.a.com/some/page, there is an iframe something like this:
Intermediate & Advanced SEO | | A Former User
<iframe src="www.b.com/some/special/path"></iframe>
Then content of this iframe is a bunch of pictures, text and numbers, as well as a group of links, linking each picture to www.b.com for example the links might be:
www.b.com/content/1
www.b.com/content/2
www.b.com/content/3 Questions: When google crawls **www.a.com/some/page, **does it pass link juice to www.b.com/content/*? Does google instead consider these to be internal links within b.com itself. because links to www.b.com/content/ ** are actually from b.com itself, since the domain of the iframe is actually: www.b.com/some/special/path 3) Is there any amount of link juice passed from www.a.com/some/page to* www.b.com/some/special/path **because this is the src= element of an iframe that a.com is hosting? Consider an alternative setup. Where instead of using an iframe the contents of the above described iFrame is actually added the the page dynamically using javascript, and a call to an API endpoint at b.com. Resulting in these links being added directly to the body of a.com without being wrapped in an iframe element. Questions:
4) Do these links that were created after page load still get crawled and credited by google? (i have heard in the past that google was going to start crawling javascript, i just don't know if this is known for a fact yet).
5) Do links created on the client side hold the same weight as a link that was served directly via the backend html generation? If both the links within the iframe and the links within the javascript embed method pass link juice. Is one preferred over the other? is one known to be more effective than the other? Thanks!0 -
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
Intermediate & Advanced SEO | | teconsite
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!0 -
Javascript onclick redirects / porn sites...
We noticed around 7 websites which with domains that were just recently registered (with privacy protection). They are using our website keywords/titles and brand name and the sites are mostly porn / junk sites. They don't link to our website directly but use a javascript onclick redirect which is why we think we aren't seeing them in our backlinks report. We've been in business for over 12 years and haven't come across sites like this before. We recently lost our first page rankings for a few of our highest converting key phrases and have been digging in to possible causes. Just wondering if these sites could be impacting our results, and how to figure out if there are more like this? Examples: nesat.net

Alt tag for src='blank.gif' on lazy load images
I didn't find an answer on a search on this, so maybe someone here has faced this before. I am loading 20 images that are in the viewport and a bit below. The next 80 images I want to 'lazy-load'. They therefore are seen by the bot as a blank.gif file. However, I would like to get some credit for them by giving a description in the alt tag. Is that a no-no? If not, do they all have to be the same alt description since the src name is the same? I don't want to mess things up with Google by being too aggressive, but at the same time those are valid images once they are lazy loaded, so would like to get some credit for them. Thanks! Ted

High resolution (retina) images vs load time
I have an ecommerce website and have a product slider with 3 images. Currently, I serve them at the native size when viewed on a desktop browser (374x374). I would like to serve them using retina image quality (748px). However how will this affect my ranking due to load time? Does Google take into account image load times even though these are done asynchronously? Also as its a slider, its only the first image which needs to load. Do the other images contribute at all to the page load time?

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.

Can Google read my backlink in Javascript??
Hi SeoMoz community! I have a software product, which our clients implement onto their websites. It is like a pop up box. I know that backlinks are very important for SEO ranking, and I really want to give our clients 2 options of product: 1. you can get the free/cheaper option if you use the code which has a keyworded backlink to our site on it 2. you can pay small fee if you don't want to use the version with a link to our site on it Now, the problem is that the product is written entirely in Javascript, and I don't think that Google crawls this, do they? Is there a way around this? Thanks for your help!
