I recently stumbled across a Google AdWords video by Derek Faylor describing how to boost AdWords relevancy. He suggests picking one keyword that is core to your business, setting it to exact match and giving the keyword its own ad group with its own tailored ads. The idea is this: if your ads closely match your keywords, you will be seen by Google as being highly relevant, so your Quality Score will increase. This will lead to a higher ad rankings, higher click-though rates (CTR) and lower costs per click (CPC).

It makes sense, and I completely agree that a highly relevant approach such as that outlined by Derek is essential to achieve great results in paid search.

However, although Derek emphasises that his one keyword per ad group strategy should only be applied to one keyword which is core to your business, there will rarely be a case where a business will only want to advertise on a single keyword. There will likely be hundreds of possible phrases that will be highly relevant to a business, and having a portfolio of hundreds, even thousands, of long-tail keywords (instead of just bidding on one or two highly generic short-tail keywords) will often achieve better results.

So is Derek’s strategy of one keyword per ad group practical if applied on a larger scale?

Let’s have a look at the pros and cons.

Advantages

1. Highly Relevant

Having one keyword per ad group makes it possible to write ads which very closely match the keyword. If the ad group contained only the keyword “brown leather shoes”, the ad could include the words “brown”, “leather” and “shoes”, possibly with prices of brown leather shoes, and take users through to the brown leather shoes landing page. However, if the ad group contained the keywords “brown leather shoes”, “blue suede shoes” and “red wellington boots”, at best, a generic “shoes” ad could be shown. Having very different keywords in the same ad group makes it impossible to create a highly relevant PPC campaign.

2. High Quality Score

As previously pointed out, having one keyword per ad group would likely achieve high Quality Scores, high CTR and strong ad rankings. Conversion rates are also likely to benefit, as highly relevant ad text will make users more pre-qualified before clicking.

3. Easy to Optimise Ads for Quality Score

If you notice Quality Score for one of your keywords is low, having one keyword per ad group makes it is relatively easy to identify which keyword / ad combination is performing poorly and make appropriate changes to improve its Quality Score.

Disadvantages

1. Unnecessary

Having every one of your keywords in its own ad group is unnecessary. If you have two keywords, “blue suede shoes” and “suede shoes blue”, what benefit is there of having each of those keywords in a separate ad group? The keywords are so similar, so you could not possibly write a more relevant ad for one if it were in its own ad group.

2. Unmanageable

Imagine a Google AdWords ad group with 2,000 keywords. If each had its own ad group, that would mean 2,000 ad groups. Imagine how difficult it would be to manage 2,000 ad groups, most of which would fail to see a single click. Since many of the keywords would be so similar, the same ads would likely be used across multiple ad groups. There would be a lot of duplication of ads and it would take forever to download reports or update changes. Quite simply, your AdWords account would become incredibly time-consuming and frustrating to manage.

3. Diluted Ad Text Performance Data

If each keyword had its own ad group, impression and click data for ads would be diluted over a greater number of ad groups, making analysis and optimisation of ads difficult and less meaningful. If , however, 10 of your very similar keywords were grouped together in one ad group, impression and click data for those 10 keywords would be aggregated for the ad group’s ads, making it easier to spot which ads are performing well and which need changing.

Balance

Although having one keyword per ad group would be nice in a perfect world, considering that there are potentially thousands of keywords that could be relevant to your business, having one keyword per ad group is taking paid search to an unmanageable level. While having one keyword per ad group is one extreme of paid search management, putting all of your keywords in one ad group is the other. The best results in paid search are achieved from a balanced approach, somewhere in between the two extremes.

So don’t just separate out keywords into their own ad groups for the sake of it. Your account will soon become unmanageable and you’ll dilute your ad text data. Instead, group very similar keywords together, even if they are broad matched. As long as your keywords are very similar, 5-20 keywords per ad group is fine. I regularly achieve Quality Scores of 9 and 10 using this approach. The key is to make sure the keywords in each of your ad groups are very similar, and that your ads are highly relevant to the ad group’s keywords.

Start with maybe 10 closely related keywords in each ad group. Once you have some data collected, use the 10% Clicks Rule to decide which of your ad groups and keywords could benefit from being split out and given their own tailored ads. It will keep your time and effort focused only on the parts of your campaign which deserve your time and effort.

As with most things in life, it’s about finding a balance. As you continually strive to improve the relevancy of your keywords and ads, make sure the strategy you are adopting is achievable and sustainable. If you put all your keywords in the one ad group, you’ll receive a poor Quality Score as users fail to engage with your ads. If you over complicate your keyword / ad group structure, you’ll end up creating a bloated paid search account and start to lose focus of your long-term goals. Find a balance that works for you.

Rule of Thumb

So unfortunatley there isn’t really a rule for the number of keywords an ad group should contain. There isn’t a ‘best’ number of keywords you should aim to have in each ad group. It’s about finding what works best for your business, for your products or services, for your set of keywords. But if you ever find yourself unsure whether a keyword should be split out into its own ad group, ask yourself this:

A keyword should only be give its own ad group if you think you could write a more relevant ad (or show a more relevant landing page) for that keyword if it were in its own ad group.

Thanks for reading. Comments and suggestions welcome.

I’m going to focus my first post on what I believe is the most fundamental concept in PPC: relevancy. Giving users what they are looking for. Directing them to where they want to go. Answering their questions.

Why? Because paid search relevancy can pay massive dividends. Not only is a highly relevant pay per click (PPC) campaign more likely to receive a higher click-through rate (CTR), higher Quality Score, higher ad rankings, lower costs per click (CPC) and benefit from less wasted spend, but users will more qualified so bounce rates are likely to fall (the number of people who immediately ‘bounce’ back), conversion rates increase and return on investment (ROI) will ultimately improve. So a highly relevant paid search campaign is definitely a good thing.

To achieve PPC relevancy, keywords, ads and landing pages need to work together in tandem. Messages in ads need to match users’ search queries, landing pages need to match messages in ads and landing pages need to relate to users’ original searches. (For a more detailed explanation of how each component interlinks, you might like to consult Acquisio’s great article on AdWords relevancy and Quality Score).

Closely matching ads and landing pages to keywords to encourage only targeted and qualified users to visit your site is a simple theory, and one that’s been around since the dawn of Google AdWords.

So nothing new then – does that mean relevancy is no longer relevant?

Well, not exactly, for two reasons…

Impossible to achieve

Firstly, relevancy can never be achieved in its perfect form. There will always be ways a PPC advertiser can improve his keyword selection, negative keyword list, match type strategy, ad copy matching and landing page selection to give the user a more engaging and personalised experience. Just like there will never be a 10.0 film on IMDB, there will never be a perfectly relevant PPC campaign. One can only strive towards perfection – towards the Holy Grail of relevancy.

Higher expectations

Secondly, the bar of relevancy is constantly being raised. As search engine continually improve their algorithms to provide users with more relevant organic search results, so paid search ads will have to improve to keep up with the growing expectations of searchers. Ads which might have been considered ‘quite relevant’ last year may be considered ‘not so relevant’ now. Ads which sufficiently answer the questions of searchers today may not do so next year when people start to demand a more personalized and tailored service.

So not only is the Holy Grail of relevancy (a perfectly relevant campaign) impossible to achieve, but it is getting more and more impossible to achieve as we speak.

But all is not lost. No-one expects perfection, after all. Just being better than the competition can reap massive benefits for advertisers. And as I’m about to point out, getting better than the competition doesn’t need to be difficult. There are opportunities everywhere.

Opportunities

Say you’re interested in visiting Sydney and want somewhere to stay. Load up Google, search for ‘Sydney hotels’ and look at the paid search results.

Of the 10 PPC ads, 9 mention the words ‘Sydney’ and ‘hotels’. Most of the ads are calling out to the user, “I have hotels in Sydney! Come to Me!” Most of the ads are relevant to your search.

But let’s say you know a little bit more about your Sydney hotel requirements. After all, you can’t be bothered clicking through each of the hundreds of paid search results (or the 22,900,000 organic results for that matter). Come to think of it, you are interested in going to Sydney next weekend, you your refine your search query.

Search for ‘weekend breaks in Sydney’ and look at the paid search results. Although most ads mention ‘Sydney’, not a single advertiser includes the words ‘weekend’ or ‘break’ in their ads. No-one is shouting out to the user, “Yes! I have weekend breaks in Sydney! Come to me!” Every ad appear to be a generic ‘Sydney Hotel’ ad that may or may not be relevant to your weekend requirements.

Suppose, instead, when searching for ‘weekend breaks in Sydney’, you saw one of the following ads:

Suppose they took you through to a special ‘weekend break’ page, specifically designed for people looking to stay at the hotel over the weekend. Along with suggestions of local Sydney sights, activities and restaurants that could easily be fitted in over a weekend were reviews from people staying at the hotel on Friday and Saturday nights.

Would you be more likely to consider this hotel in your plans? I know I might.

More opportunities

Okay, only 36 people searched for ‘weekend breaks in Sydney’ in June. But these were 36 people who knew what they were looking for and were delivered poor, generic, one-message-fits-all ads.

‘Weekend breaks in Sydney’ is just one example. Imagine all the hundreds of similar qualified searches people could make to find your products or services. 880 people searched for ‘Sydney CBD hotels’ in June, but most advertisers fail to mention ‘CBD’ or even their location in their ads. ‘Sydney hotels the rocks’ had 390 searches, but only one advertiser mentions the phrase ‘The Rocks’ in their ads. 73 people searched for ‘3 star hotels in Sydney’ but only a handful of advertisers mention ’3 star’ or ‘3*’ in their ads. These are people who know what they want are willing to part with their cash if they can find it.

It doesn’t take long to find hundreds of other examples of keywords that have significant search volume and are being poorly served. There are opportunities everywhere.

What’s more, as demand for better search results grows, people will start making more of these 3, 4, 5 and 6-word searches and expect better, relevant, more personalised results. The winners will be the advertisers who cater for them. The losers will be the ones who don’t.

So how do I go about improving the relevancy of my AdWords campaign?

Patience

I’m not going to pretend there is a quick overnight fix (because there isn’t). A highly relevant AdWords campaign takes patience, commitment and dedication.

Nor are there techniques that work for everyone. The whole purpose of this blog is to share with you the PPC techniques I have found to work in my experience, although I recognise they will be far from the be-all-and-end-all of paid search management so I welcome your ideas and comments. Paid search is an ongoing battle to become better and better, and it isn’t going to stop any time soon.

But to keep things nice and simple, here’s a quick 5 minute run-down of the essentials of creating a highly relevant PPC campaign:

Keyword Research

Research keywords that people are searching for. There are free tools out there, such as Google’s keyword tool, so use them. Build up a comprehensive keyword list. Not just with generic, high-volume keywords, such as ‘cheap Sydney hotels’, but also with long-tail keywords such as ‘cheap hotels in Sydney CBD’ and ‘cheap hotels Sydney Darling Harbour’. Long-tails can collectively be of significant volume and provide a great opportunity for tailored ads.

Then research negative keywords, lots of them. Why waste money on clicks you know are completely irrelevant? Use the keyword tool to identify keywords that might broad match to ‘cheap Sydney hotels’. Go through each result, making a note of anything you think is irrelevant. Is your Sydney hotel miles away from Sydney Airport? If so, add ‘airport’ as a negative keyword. Keep brainstorming negatives until you have at least a hundred.

Ad Group Structure

Once you have done your initial research, group your keywords into small, closely themed ad groups of generally no more than 20-30 keywords each. Write ad descriptions that are relevant to the ad group’s keywords and include the ad group’s keywords in your ads where possible. If you think you could write a more relevant ad for a keyword if the keyword was in its own ad group, split out that keyword into its own ad group and write a more relevant and tailored ad for it.

Think of the keyword as the question and the ad as the answer. Keep asking yourself, “If I searched for this keyword and saw this ad, is it answering my question?” If not, change it so it does.

Include offers and prices that are relevant to the keyword. In your ‘Sydney Hotels Christmas 2009′ ad group, how about mentioning Christmas 2009 prices or early booking discounts?

You’re trying to make your ads as relevant as possible to the user’s searches so think about how you could angle your products or services to appeal to users searching each of your keywords.

Next, deep-link your keywords to the most relevant page on your site. Don’t have a relevant landing page for a set of keywords? Write one.

Rinse and repeat until you have hundreds of ad groups, each with tailored ads and landing pages that match the keywords they contain.

Optimization

Then get optimising. Test new keywords. New ads. New landing pages. Two keywords in the same ad group getting a lot of volume? Split the two keywords out into separate ad groups and write new ads that better match those keywords.

Run search query reports to highlight searches your keywords have broad-matched and phrase-matched to. Are they relevant? If so, ad them as new keywords in new ad groups and write tailored ads for them. If not, add them as negative keywords to prevent your ads showing for them again.

It may seem like a lot of work but it’s worth it. With patience, your CTR will start to increase. So will your Quality Score. People will start to spend longer on your site and view more pages. Returning visitors will rise as people decide to come back. Conversion rates will grow and sales volume will increase.

The Holy Grail of relevancy is not something you can achieve overnight, or achieve at all for that matter. It is only something you can strive towards. PPC success favours the dedicated. So keep testing and optimising.
