[HOW TO] Put noindex,follow meta tag on specific pages SEO

Hello all,

In this tutorial i will show you how to put the meta tag <meta name="robots" content="noindex,follow"> on specific pages in OpenCart.

Q.A:

Why would i do this?

Out of the box is OpenCart pretty SEO-friendly, but you can always do this better with some tricks and fixes. This will put the meta tag on specific pages such as onsite search results. This is crucial for SEO purposes to avoid certain stuff like duplicate content and low quality pages. If you do not do this it can result bad SEO and in worst cases you can get penalized for bad content.

Why not use /disallow in robots.txt?

I have seen lost of posts in this forum on this case of problem, the thing is that the robots.txt do not "unindex" your pages and many of the search engines do ignore this file. And Google has announced that noindex,follow meta tag is the code you need.



The Tutorial:

To make this happen you need to code some in the core files. You can also make this with a VqMod file if you're not comfort with coding inside the core files.

Lets get going.


Find this file:

catalog/controller/common/header.php
Find line:

Code: Select all

$this->data['links'] = $this->document->getLinks();
After put this line:

Code: Select all

$this->data['robots'] = $this->document->getRobots();

system/library/document.php
Find line:

Code: Select all

private $description;
Above put this line:

Code: Select all

private $robots;
In same file you need to find this line:

Code: Select all

public function setDescription($description) {
Above put this line:

Code: Select all

public function setRobots($robots) {
		$this->robots = $robots;
	}
	public function getRobots() {
		return $this->robots;
	}

catalog/view/theme/YOUR_THEME/template/common/header.tpl
Find line:

Code: Select all

<?php if ($description) { ?>
<meta name="description" content="<?php echo $description; ?>" />
<?php } ?>
After put this line:

Code: Select all

<?php if ($robots) { ?>
<meta name="robots" content="<?php echo $robots; ?>" />
<?php } ?>
We have now done so the controller can put the meta tag on the pages we want them to have. What we need to do next is to define which pages to have this nice little bit of code.

This will be an example to put noindex,follow on search page.

Find this file:

catalog/controller/product/search.php
Find:

Code: Select all

$this->load->model('catalog/category');
After put this line:

Code: Select all

$this->document->setRobots('noindex,follow');
And there you have it. As i said before you can do this with VqMod. I don't know how to attach files on this forum, otherwise i would do it for you with some more pages to have this.

Hope this will help some people that want to tweak OpenCart even more in SEO purposes. Please check out the extension parts of this. Cause i am in work to make a real module for this.

Awesome little modification. The author was kind enough to help me with this and I've already got it installed on my site. It works like a charm.

As Search engines become smarter and more picky than before, it's extremely important that your site is sculpted the right way to avoid duplicate content ;)
Thanks again

I'm always interested in SEO since I am in a pretty competitive product market so I need to ask: Does this actually help?

Also if it does help, would it also help to do that if a sites uses the "Category" module in the column?
Reason I ask, is if you use the links in the header and use the Category module, you will in effect double the links on your page. Most SEO things say to have 100 or less links on your page BUT still others say that is an old "don't do" rule and is outdated.

Hi,

I completed the features - "noindex, nofollow" or "index, follow" meta tag on specific product pages . It's work very smooth.

Features:
- A product doesn’t perfect about contents, images..., you don't want it's shown on search tools as google, yahoo, bing... Let use “no index” – You will use this fuction to turn on the attribute in admin.

You can get more detail as link:

Very cool. Thank you.

I had a bit of a hard time adding to https://www.site.com/account/return/insert page?

But here is what you need to look for on this file catalog/controller/account/return.php

Code: Select all

public function insert() {
		$this->language->load('account/return');

		$this->load->model('account/return');
And then add this line after:

Code: Select all

$this->document->setRobots('noindex,follow');
thx

Hey.. nice extension. I have a Q though.. is it possible to go one step further?

I.e. <if product is in 'cat id' then add noindex tag> ?

Product 1, 2, 3 etc is in 'offers' category. I want to add noindex to all products in this category. But leave indexing on all other categories ?

SEO is much more links, spam and directories listing. This was done until 2014, but now the Google algorithm has changed and those who have stayed in those techniques do only harm in the site they support. You can read on this SEO blog and learn more but as a company you should be interested in increasing your turnover first and establishing your brand first and foremost.
