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!

What a great response! Just what I was looking for. Thank you!

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?

Is Removing Breadcrumbs Detrimental for SEO?
We have full navigational breadcrumbs on our site for the menu and the brand menu. i.e. Home > Clothing > Jackets Brand > Brand Name > Brand Jackets There's been talk of removing this and having it like Chico's does, where on item pages they just have a link at the top to previous category (i.e. you're on a shirt product page and at the top it says "Back to Tops" instead of listing Home > Clothing > Tops) Is doing something like this detrimental to SEO? From what I've read Breadcrumbs are for user experience but I just want to be sure.

Retaining Image Search Rankings After Migration
Hi There, I have a client with a very interesting dilemma out there. If you do an image search his images appear quite high in the rankings. However the way he achieved this isn't exactly within Google's guidelines. He is basically hiding the images within CSS. The reason behind this is that the pages have changed over the years and the images didn't fit in with the new existing text but he still wanted to maintain the high image search rankings. He is now changing to a brand new site and so this page he has been able to tweak successfully before, will no longer exist. He want's to know what is the best way to maintain his image search rankings. will a 301 redirect be enough? I know the morality issues of hiding images, but I want to know if he did what would be the best way to preserve his current image rankings. Kind Regards Neil

How does a mega drop-down affects SEO?
We are looking at implementing a "mega drop-down" as our main menu on our website. Will that be good or bad for SEO? My company is a big tour operator so our website contains a lot of pages describing all our destinations, hotels etc. We have noticed that our visitors have some trouble to navigate to all this pages since it requires a lot of clicks to reach a specific page. In order to make this easier we have looked at this popular mega drop-down thing that we all love. But what about Google? Will Google love or hate us for doing this? An example showing what I mean by mega drop-down: http://www.phonehouse.se/
