Loading images below the fold? Impact on SEO
-
I got this from my developers. Does anyone know if this will be a SEO issue?
We hope to lazy-load images below the fold where possible, to increase render speed - are you aware of any potential issues with this approach from an SEO point of view?

Happy to help!

Thanks Tom!
As always, an amazing response.

Hi Chris sorry for the late reply absolutely you can do this by using a plug-in cloudfare or PHP code
- https://wordpress.org/plugins/wp-deferred-javascripts/
- https://wordpress.org/plugins/defer-css-addon-for-bwp-minify/
Another plugin that does this solution but providing an administration area to configure it manually is Autoptimize, that allows to define a specific CSS code in a independent way of your theme CSS stylesheet

- https://seo-hacker.com/optimizing-site-speed-asynchronous-deferred-javascript/
- http://www.laplacef.com/how-to-defer-parsing-javascript-in-wordpress/
The solution of these problem is removing those render-blocking scripts. But if you remove them, some plugins may not work properly. So, the best solution for the smooth rendering is:
1. Remove them from your website source page.
2. Use a single script, hosted by Google as the alternative.
3. Push down the new script at end of the page ( before “” tag).
Here is how to do it.
Copy the code from the following link and paste at your theme’s function.php file.
function optimize_jquery() { if (!is_admin()) { wp_deregister_script('jquery'); wp_deregister_script('jquery-migrate.min'); wp_deregister_script('comment-reply.min'); $protocol='http:'; if($_SERVER['HTTPS']=='on') { $protocol='https:'; } wp_register_script('jquery', $protocol.'//ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js', false, '3.6', true); wp_enqueue_script('jquery'); } } add_action('template_redirect', 'optimize_jquery');
Save the file and you are done! Now recheck the source of any page and you won’t see those two scripts at the head section. Alternatively, you can see the Google hosted JavaScriptscript source at the end of the page.
That’s all! Now the visible section of your page will be rendered smoothly.
Defer Loading JavaScript
Another suggestion from Google Page Speed tool is “Defer JavaScripts”. This problem happens when you use any inline JavaScripts like the scripts for Facebook like box or button, Google plus button, Twitter button etc. If you defer the JavaScript then the scripts are triggered after loading of the entire document.
How to defer JavaScript at WordPress
1. Create a JavaScript file and give the name as defer.js.
2. Place the JavaScripts codes that you want to defer into the defer.js file. For instance, if you want to defer Facebook like box script, paste the following at that file.
(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_GB/all.js#xfbml=1&appId=326473900710878"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));
3. Save the file and upload at your theme folder.
4. Now, copy the following code and paste at the head section of the source page. Here in WordPress, open header.php file of your theme and paste the code before the closing head tag.
Make sure to put the correct path of defer.js. For example, the source path should be like this:
/wp-content/themes/theme_name/defer.js ______________________________________________________________________________________________
I hope that helps,
Tom

Thomas,
Can this be implemented on a Wordpress site?
Apologize for hijacking!

lazy loading images is not as good as deferring an image. Because lazy loading images can cause issues can cause JavaScript issues that will not cause problems if you deferred the image instead of lazy loading.
Defer images you will have a easier time the method discussed here does not hurt search engine optimization in fact it will help it because increased load speeds or what people perceive as an increased load speed always helps the end-user.
Here is the best way
https://www.feedthebot.com/pagespeed/defer-images.html
This is where we defer the images without lazy loading
In the scenario of a one page template, there is no reason to do all the things that lazy loading does (observe, monitor and react to a scroll postion).
Why not just defer those images and have them load immediately after the page has loaded?
How to do it
To do this we need to markup our images and add a small and extremely simple javascript. I will show the method I actually use for this site and others. It uses a base 64 image, but do not let that scare you.
The html
The javascript

I have looked for information on this in the past and come up empty handed. With page speed Google really pits you against best SEO practices. I think if you follow most of the page speed insights you can severely limit your SEO. How many images are you talking about, how does Google render the page in their fetch as Google?

Display ads and SEO
I have a section(no. of webpages with content) on my site with display ads. The site is mainly for UK visitors. I want to show ads to UK visitors but not US visitors. Rest of the content will be the same for UK and US. There will just be 1 page with same UrL for US and UK. Hence, no href lang tags are being used.

Some SEO 2016 questions
Hello MOZ Community, I have some questions where the following is still working for seo in 2016: Is an exact keyword in the domain still a good start? If a domain contains the most important keyword does one still need subfolders with that keyword in the url? Do you need multiple subpages so the main url becomes stronger? Is linkbuilding still the number one factor? Thank you for your thoughts!

SEO for User Authenticated Content
Hi Everyone - I have a potential client who is seeking SEO for a site that contains about 95% of content only accessible through user authentication . Does anyone have tips for getting this indexed without having to open it up to the public? I was considering adding "snippets" into the robots.txt or creating an additional page with snippets linking to the login page. I'd appreciate any thoughts! Thanks!

International Seo - Canada
Our organization is currently only operating in the USA but will soon be entering the Canadian market. We did a lot of research and decided that for our needs it would be best to use a subfolder for Canada. Initially we will be targeting the english speaking community but eventually we will want to expand to the french speaking Canadians as well. The question is - is there a preferred version in setting up the subfolders: www.website.org/ca/ -- default will be english www.website.org/ca/fr/ - french www.website.org/en-ca/ - english www.website.org/fr-ca/ - french www.website.org/ca/en/ -english www.website.org/ca/fr/ - french Thanks
