Contextual advertising: choosing keywords for a better return
Contextual advertising is one of the fastest ways to attract customers. Its effectiveness depends directly on choosing the right keywords, which determine who sees your ad, how much a click costs and the result you achieve.
How to choose paid search keywords carefully to get the best return from your advertising budget.
Why is keyword selection so important for paid search?
Contextual advertising on platforms such as Google Ads and Yandex Direct works through an auction: you pay for ad impressions or clicks while competing with other companies for users' attention.
Your chosen keywords determine:
Who will see the ad
When and where it will appear
How much it will cost to acquire one customer
What conversion rate you can expect
Poor keyword selection can mean paying to reach irrelevant audiences, generating too few enquiries and wasting the advertising budget.
Choosing the right keywords for effective paid search

Target audience analysis: understanding needs
Before compiling a keyword list, understand:
Who is your customer?
Which problems or needs does your product help them address?
What phrases might they use when searching for a solution?
Example:
If you sell bespoke kitchens in Moscow, prospects may search for 'buy bespoke kitchen Moscow', 'order affordable kitchen' or 'complete kitchen design and installation'.
Tip: Define your ideal customer and list all the search queries they might use.
-
Using keyword research tools
Many free and paid tools are available for finding relevant keywords:
Yandex Wordstat shows how many times users enter a particular Yandex query each month.
Google Keyword Planner is a comparable tool from Google.
Serpstat, Ahrefs and SEMrush are paid platforms for detailed competitor analysis and additional keyword ideas.
What to consider:
Search volume: how many times users enter the query each month.
Competition: how many advertisers are competing for this query.
Commercial potential: how closely the query relates to a purchase.
Example:
The query 'buy an affordable kitchen' has strong commercial potential, while 'kitchen design ideas' is primarily informational.
-
Long-tail keywords
Long-tail keywords are more specific queries of 3-5 words that clarify the user's intent.
Examples of long-tail keywords:
"Buy an affordable corner kitchen in Moscow"
"Order a fitted kitchen with installation in the Moscow region"
"Bespoke kitchens for a small flat"
Benefits of long-tail keywords:
Low competition → a lower cost per click
High conversion → users entering specific queries are already ready to buy.
Takeaway: always include long-tail keywords in your advertising campaign.
-
Negative keywords: protect your budget from irrelevant searches
Negative keywords prevent ads from appearing for specified terms, filtering out users who have no intention of buying.
Examples of negative keywords:
free
DIY
photo
download
drawing
Why this matters:
Without negative keywords, your ad may appear for irrelevant queries, such as:
'free kitchen designs' or 'how to assemble a kitchen yourself', meaning you will be wasting money.
Tip: create a negative keyword list before launching your campaign and update it regularly based on search query analysis.
-
Grouping keywords and creating relevant ads
Choosing keywords is only part of the task. Grouping them correctly is essential for creating highly relevant ads.
How it works:
Organise similar queries into separate groups.
Write a unique ad for each group that clearly answers the user's query.
Example:
'Buy a bespoke kitchen' group → an ad selling kitchens.
'Install a kitchen' group → an ad for kitchen installation services.
Result:
High relevance improves quality scores in Google Ads and Yandex Direct, reduces cost per click and increases conversions.
-
Regular keyword analysis and optimisation
Keyword work continues after campaign setup. To get the best return from paid search:
Track which keywords generate enquiries and which only consume budget.
Disable ineffective queries.
Add new keywords based on analysis of actual search queries.
Tools:
Google Ads and Yandex Direct provide detailed performance statistics for each keyword.
