The Ultimate Guide to Google Ad Sitelink Extensions

Make your Google adverts bigger and increase CTR by up to 50% with Sitelink extensions.

Get the stats and facts so you can make the most of this important Google Ads feature.

Sitelink extensions allow you to display extra links below your adverts, allowing you to direct users to the most relevant pages within your website.

Here is an example of an advert for bananas 🍌, with sitelinks:

Google Ads sitelinks example

There are several benefits of displaying sitelink extensions alongside your adverts:

  • Allow you to occupy more space on the first page of Google
  • Increases the likelihood that your advert will get clicked on
  • By using Sitelink extensions you can increase your CTR by around 20-25% on unbranded terms
  • Increase CTR by up to 50% on branded terms
  • Unlike callout extensions, sitelinks are clickable
  • Direct people to the most relevant landing page which can help increase your conversion rate
  • Highlight certain benefits and features, for example, that you offer free shipping
  • Push other products and services that you provide.

Sitelinks will often be shown alongside your advert if you appear in one of the top 3 positions, and in some cases a short two line description will be shown below your sitelink extensions.

These are known as enhanced sitelink extensions and I will come on to those later on in this article.

There is no cost for setting up sitelink extensions, you just pay the same cost per click as you would for your standard advert.

If somebody clicks on one of your sitelinks twice, then this will be counted by Google as an Invalid click and you will not be charged for it.

How effective are sitelink extensions?

When PPC Hero implemented sitelinks on their campaigns they saw some hugely impressive results. Here is the data for two months before the sitelinks were added and then two months after the sitelinks were added:

Their CTR increased significantly from 1.16% to 1.90% which is an increase of 64%.

How effective are sitelink extensions

This test should be fairly robust as it was only conducted in campaigns where there were no changes to the adverts, keywords or campaign settings that might effect their click-through rate.

The only real limitation is the fact that it is only a study of one account in a single market so the results may vary depending on the market.

Sitelink extension best practices

1. Test your sitelink extensions

Just like you would split test your adverts, you need to split test your sitelink extensions.

When you do this you should compare your sitelink performance with other sitelink extensions as opposed to your overall ad performance.

To do this head down to the bottom of this article and read the sections on analysis

You also need to analyse what is working well as this will give you insight into what searchers are attracted to. A great example of how this can be used was given by Hayley Coutinho from Receptional.

Hayley suggests that if a sitelink to your sales offer page is receiving a high CTR, you could try other sitelinks that focus on price, savings or promotions you have running.

If you have a sitelink directing users to a product category perhaps you could use this information to create a new sitelink that uses a price led title instead, for example, ‘Bow Ties From £9.99’ instead of just ‘Bow Ties’.

2. Structure your sitelinks to segment users

Many advertisers don’t fully take advantage of the fact that sitelinks can be added at either campaign or ad group level, which means that you need to have a logical structure.

For example, if you have an ad group that sells red men’s shirts, the chances are that there will be several different sizes and styles of these shirts.

Some will have a checkered patten, some will have a striped patten, some will be long sleeve, some will be short sleeve.

So you can use sitelinks to drive people to the most relevant section before they even hit your website. So, for example, you have an ad group with an advert for men’s red shirts, you could create ad group level sitelinks such as “shop striped red shirts”, “shop checked red shirts”, “shop plain red shirts”.

This way you can direct people to the most relevant type of shirts straight from your adverts, so they don’t have to search around on your website for them, which will help increase conversion rates.

Here is an advertiser doing this for their yoga pants.

They have a generic yoga pants advert in an ad group and they have added sitelinks to direct people to the most specific type of yoga pants.

example ad2 tip1

You can also use sitelinks to segment users using by brand.

People will be interested in the different brands of product that you sell. Here was the example that he gave.

The Gap has five brands including: Banana Republic, Old Navy, Athleta and Piperlime. For the Gap, Sitelinks helps drive sub-brand awareness and drive users to the most relevant brand.

My final example of segmenting users is by using sitelinks for your branded campaigns.

Before sitelinks were introduced you had no other option than to send people directly to your homepage.

However, if you use sitelink extensions, then you can make your brand traffic work harder by using sitelinks to drive people to the most relevant category of products.

branded sitelinks with descriptions

Here is an example of Nike using sitelinks to direct their branded traffic to their most popular category.

3. Use a call to action

A good way to improve the proportion of people who click on your sitelink extensions is to include call to actions, such as “shop” or “buy” instead of just saying “striped red shirts” instead say “buy red shirts” or “shop striped shirts”.

You can also use this technique if you are using adwords for lead generation. Loredana Bleiziffer from Periscopix recently published a case study where they used this technique.

She ran a test where they used call to actions in their sitelinks to get users to take a particular action. The account that she ran it on was generating enquires for student flats.

Their objective was to measure the number of blog visits, general enquiries, brochure enquiries and bookings, so she added different sitelinks that told users to take these actions. Here are the results.

sitelinks with call to actions

As you can see by using call to actions, there was a significant increase in click-through rates and conversion rates.

You can apply this to just about any lead generation business.

Not only will general enquires have value to your business, but somebody downloading a white paper, a case study or your pricing guide is also likely to have value to your business, so you can add call to actions within your sitelinks to encourage users to take these actions.

4. Build trust with searchers

Many searchers will want to learn how good your company is before they purchase your products or sign a contract and start working with you.

A good way to build trust especially for B2B companies is to promote the following pages:

  • Case studies
  • Success stories
  • Testimonials
  • Certifications
  • Awards

5. Use sitelinks for sale and promotions

Sitelink extensions are a great way to run promotions, without having to change your ad text.

This is especially useful if you are a large ecommerce company and you want to run a sale across your whole campaign which might have tens of thousands of adverts.

Sitelinks can be easily set up and allocated to specific ad groups or whole campaigns which gives you a large amount of flexibility.

They can also be scheduled so that they will only run for a set number of days while you are running your sale and then be paused automatically when your sale has finished.

They can also be very useful for running seasonal promotions such as Black Friday, Cyber Monday, Christmas, Easter and various other seasonal occasions.

Here is an example of Gant using sitelinks to advertise their Black Friday sale:

using sitelinks for promotions and deals

6. Have at least 4 sitelinks on desktop and 6 on mobile

One classic mistake that I see quite regularly is not having enough sitelinks per ad groups or campaign.

The maximum number of sitelinks that Google will show is 4 on desktop devices and 6 on mobile devices.

Ensure that you have at least this many in each ad group/campaign otherwise your sitelinks may not show.

Enhanced sitelinks

Extended sitelinks allow you to add an additional two lines of description below your sitelinks, which turns them into mini ads by themselves.

additional lines of text on sitelinks increases your ad real-estate

Here is an example below, as you can see they are a great way to occupy more space on the first page of Google.

However, to be shown they require a high Ad rank, which means that they only show when you have a high combined Quality Score and CPC bid.

For this reason we generally only recommend adding these to your branded, high spend and high ROI campaigns.

Do enhanced sitelinks work?

Wordstream ran two case studies into enhanced sitelink extensions.

The first one was on a travel agency account in the UK. To keep their tests fair they kept their sitelinks consist ant across their account.

Here are their findings:

Do enhanced sitelinks work

As you will see from this graph, there was only a small increase in click-through rates when using enhanced sitelink extensions compared to standard sitelink extensions.

The increase was a very small 0.04%. However, the most concerning result was the drop in conversion rate of -17.1%.

The main limitation with this study is that it is in a seasonal account where a change of 3 weeks could make a huge difference to CTR and conversion rate, which could explain the decrease in conversion rate.

When looking at the actual sitelink contribution themselves Wordstream found very different results.

sitelink contribution metrics to conversions

Here you will see that there was very little difference in click-through rates for upgraded and non-upgraded ad extensions.

However, it actually turns out that adverts that have upgraded sitelinks did actually have a higher conversion rate.

They also ran a test on an ecommerce campaign for a shoe retailer.

This is more likely to give consistent results as there will be less of a seasonal effect.

Here they found that there was an increase in click-through rate of 22.25% and an increase in conversion rate of 25.3% which can make a fairly large improvement to your account. There was also a 13.2% increase in multiple conversions.

Google Ad sitelinks improve campaign performance

These results were also found when looking at the individual sitelink contribution.

The individual sitelinks had significantly more impact on clicks and conversions.

The two graphs show that by adding extended sitelinks it improved both click-through rate and conversion rate.

Mobile sitelink extensions

If you are running your adverts on mobile devices, then you need to create mobile optimised sitelink extensions.

You might be wondering what makes a mobile sitelink extension different from a normal sitelink extension?

The answer – the length of the sitelink.

Even though on both mobile and desktop devices the sitelink character limit is actually the same, which is set at 25 characters, you don’t actually want to use all of the 25 characters on mobile devices or you are going to end up with the problem that this advertiser is having here.

You will notice that when you use a 25 character long desktop sitelink on mobile devices that only one sitelink will appear.

However, if you instead create shorter sitelinks, where you limit the length of your sitelink to between 15 and 17 characters, you can display several sitelinks below your adverts, like these advertisers have done here:

mobile ad sitelink example

Creating mobile optimised sitelinks is straight forward, when you are creating your link text limit yourself to just 15-17 characters.

You also need to tell adwords that you only want the extension to show these shorter sitelinks on mobile devices, as you want to show longer 25 character ones on desktop devices as these allow you to occupy more space on the first page of Google.

To tell Google to only show your shorter sitelink extensions on mobile devices then just check the mobile preference box when creating them.

mobile preferred sitelinks improve CTR

Simply by creating shorter sitelink extensions such as these, it will allow you to increase your click-through rate on mobile devices by 15% according to a study which was conducted by PPC Hero.

How to set up sitelink extensions

Step 1. Go to the Ad extensions tab within your account.

Step 2. From the dropdown select ”view:sitelink extensions”

create a sitelink

Step 3. Click, + Extension

Step 4. Click ”New sitelink extension”

Step 5. Once you see a popup that looks like the one below you need to setup your sitelink.

Enter what you want your sitelink to be in the link text box and the URL that you want people to be directed to once they click on your sitelink below.

Screen Shot 2015 11 29 at 02.08.47

Step 6. If you are creating shorter 15-17 character sitelink extensions that should only be shown on mobile devices check the mobile preference box, otherwise leave this unchecked.

Step 7. If you would like to create enhanced sitelink extensions then you should enter the optional two lines of description.

As I mentioned above, as a rule of thumb, only add the two optional lines of description if your sitelinks are for your branded campaign, otherwise they are unlikely to be shown.

Step 8. If you would like to schedule your adverts to show only in a certain date range, then you should expand the “start/end date, scheduling” tab and then enter the dates or times that you want your sitelinks to show. 

This can be useful if you are running a promotion for a limited time.

Step 9. If you are an advanced Adwords user then you may want to tag the URLs of your sitelinks so that you can analyse your data in Google analytics, which I will talk about later in this article.

Step 10. Click save and there you have it, your first sitelink extension.

Why are my Sitelink extensions not showing?

There are several reasons why your sitelinks may not be showing alongside your adverts.

Reason 1. Ad not appearing in the top 3 positions

One reason may be that your advert is not appearing in one of the top three positons.

Only these top 3 positions are eligible to show sitelinks so if you’re not placed there, your sitelinks sadly won’t appear.

Reason 2. Ad rank is too low

Ad rank is a simple equation. Quality Score x CPC Bid = Ad rank

Google Ads Ad Rank

So if you want to improve your ad rank and increase the percentage of time that your sitelink extensions are being shown, then you need to either increase your bids or improve your quality score.

This is the reason that most of the time extended sitelinks will not appear. They will generally only appear when you have a very high Quality Score and CPC bid combination, a common example of this would be your branded keywords.

Google also states that they don’t just look at the quality score of the keywords, but they also take into account the relevancy of the landing page to the sitelink. So, to improve the chances of being shown, ensure that your landing page and sitelink text are closely aligned.

Reason 3. Your sitelink extensions were not approved.

For your sitelink extensions to show they must first be approved by Google. To see if your sitelink has been approved check the status column while viewing your sitelink extensions, within the ad extensions tab.

If your ad has been disapproved then ensure that you are not breaking any of Google Ad sitelink policies.

Sitelink data analysis

There are several tools within the AdWords interface that allow you to measure the effectiveness of your sitelink extensions.

These can then be used to make strategic decisions to optimise your sitelinks.

When analysing your sitelink extension data, you firstly need to ensure that you have enough data to make a statistically significant decision.

Sitelinks drive much lower volume than your main ad will so you may have to wait a couple of months until you have enough data.

Secondly treat your sitelink extensions like you would your ad copy and learn from your winners and losers.

Write new sitelinks based on your winning sitelink language.

There are three main reports for analysing the effectiveness of sitelink extensions.

Report 1. Analyse if people are clicking on the sitelink or the advert:

The first one will allow you to see whether users clicked on the headline of your adverts or whether they clicked on the sitelink extension itself.

To view this report click “segment” and then “click type”.

Here is an example of a report:


You may wonder why your sitelink has a much lower click-through rate than the headline of your advert. The reason for this is that searchers are much more likely to click on the main advert than they are the sitelinks below them.

Report 2: Analyse the performance of the individual sitelink ad extensions

This report will allow you to see the click-through rates of the individual sitelinks themselves.

This is really useful data for conducting split tests of your sitelink extensions.

To view this report click “segment” and then “This extension vs another”.


The ”This extension row” of this report will show you the individual data for that extension such as the click-through rate and cost per click.

The “other” row shows you the data for the other parts of the advert that this extension was shown alongside which allows you to determine if this specific sitelink extension contributed to the overall performance of the ad.

Report 3: Sitelink performance on mobile devices

To see this report view your sitelink extension data and then click “segment” and then select “devices”.

blanked sitelink mobile

This will then show you a report that looks something like this, which allows you to see how your sitelink extension performed on mobile compared to desktop or tablet devices.

Report 4: Ad extensions tab

This report allows you to see the overall performance of your adverts while sitelink extensions were being displayed.

Using Analytics to track sitelink performance

If you are interested in tracking your sitelinks in even more depth using google analytics, then I highly recommend reading ‘Measuring your sitelinks from your Google Adwords campaign’ by Brittany Baeslack.

I would also recommend ‘Measuring sitelink performance in Adwords and Google analytics’ by Andrew Barberson.

By using the analytics interface you can drill down and find out more information about your sitelinks, such as which campaigns and ad groups triggered them.

You can also setup custom reports to show you your statistics for your sitelinks.
