SEA agency

Searchbooster is a Google Ads SEA agency specializing in paid advertising in Paris, which has the unique feature of working on all digital channels and devoting a significant part of its activity to the redesign and development of showcase and e-commerce websites of all kinds.

We are one of the few medium-sized agencies that are truly specialized in digital marketing and can deal with SEO, SEA, social media, content management, and design and development of showcase websites, e-commerce websites, and PWA and native iOS and Android apps.

We work long-term for our clients for all their advertising needs, whether it be Google Ads, Bing Ads, Facebook Ads, Twitter Ads, LinkedIn Ads, Amazon Ads, or of course, paid advertising on the display network.

If you decide to use a digital agency, consult us because our 360-degree approach allows for a consistent approach by acquisition channel and also takes into account the websites on which your campaigns will direct your prospects in order to maximize visits and conversions.

It is important to know that before any commercial proposal, if you have already conducted Ads campaigns, either personally or through one of our colleagues, we will systematically conduct an audit of your Ads account to measure the impact of your sponsored link advertising campaigns.

This assessment will allow us to implement a paid search engine advertising (SEA) strategy that will integrate a very thorough analysis of what has already been done in terms of acquisition strategy and results obtained, notably by analyzing the following key indicators:

  • Impressions volume
  • Number of clicks
  • Number of conversions
  • Conversion rate
  • Click-through rate
  • Conversion value
  • Impression rate on the search network
  • % of positioning in top 1
  • Bidding systems used: CPA, CPC, CPM, manual, automatic
  • Modification history

To do this, it is desirable that we have access to your Google or Facebook Ads account, as well as your Google Analytics account if you have one.

Thus, we will be able to have a very detailed view of your past sponsored link campaigns and the improvement levers that we can consider. We will be able to share with you the conclusions of our free SEA pre-audit report before making a commercial proposal for Google Ads SEA support with our consultants certified by Google.

The initial audit and proposal for a paid advertising campaign (ADS)

In any case, and in the event that you have never previously carried out Google AdWords or other ads campaigns, we will have an interview with you in order to fully understand the following points about your business:

  • What is your main activity?
  • Who are your prospects and customers? 

  • What is your catchment area?
  • What products or services do you want to sell, to whom, and how?
  • Who are your competitors?
  • What are your key differentiating factors?
  • What do you want to highlight to attract your future customers?
  • Do you have landing pages for your Ads campaigns on your website, or do we need to create them?
  • What do you want to achieve with Ads (leads, sales, brand awareness, inbound calls, content downloads?)?
  • How much are you willing to invest per lead or sale?
  • What is the daily budget you are willing to invest?

Trafic sur le web 

  • cost per click (CPC)
  • cost per landing page view (CPLPV)

So we will be able to quickly propose the implementation of a paid referencing strategy (called PPC Pay Per Click by Anglo-Saxons) by detailing the following points:

  • The keywords on which we propose to bid
  • The search volume per keyword and the recommended bidding level
  • The recommended Ads account structure with the different required levels (Campaigns, Ad Groups, Ads, Extensions)
  • The temporal and geographical planning of campaigns
  • The recommended targets 
  • The proposed ad templates (static, dynamic, display, videos, etc.)
  • The budget allocation by acquisition lever (Google, Facebook, search network, display, Google Shopping, Amazon, etc.).

Thus, we can work to build your campaigns as soon as the above elements are validated based on the file we will have given you.

Activating your PPC campaign and monitoring it

Many customers ask us the following questions:
  • How much should be invested per day?
  • Is 5% click-through rate good?
  • Is a 1% conversion rate a good conversion rate?
In fact, unless we perfectly know your sector and work with your direct competitors (which we prohibit ourselves from doing), it is impossible to answer these questions before activating your ADS campaigns. Our recommendation for the budget is to set a sufficient daily budget to be present on the keywords identified by us based on the daily search volume and the indicative CPC provided by our tools. Regarding click-through rates and conversion rates, there is no absolute good number because it depends on your industry, the potential of the market, the competitive environment, the amount you are willing to pay per click, the quality score of your page which will influence your CPC… However, what will be important is to pay the right cost per click and to have the click-through rate increase through campaign optimization.

What is important is that your agency continuously optimizes your campaigns by regularly monitoring them to identify keywords that perform better than others, those to “exclude” because they do not generate clicks or conversions, better-positioned competitors, and therefore constantly adjusting the campaigns. 

Serious agencies like Searchbooster do not hesitate to use artificial intelligence tools (paid) that connect to Ads accounts to make recommendations and launch automatic alerts to our teams if, for example, bids soar or if certain ads perform better than others. 

Thus, your agency will be able to continuously optimize your campaigns to reduce CPC, increase conversions, increase CTR, strengthen bids on mobile, for example, or at certain times if the conversion rate is better.


Because a mandate from you involves being accountable to you, we will send you a complete report on the performance of your ADS campaigns on a monthly or weekly basis and organize a meeting to present: 

  • The performance of your Ads campaigns for the previous period
  • Our main adjustments
  • Our recommendations for the upcoming period, particularly in terms of budget.
  • The main KPIs of your paid search campaigns.

So don’t hesitate to contact SearchBooster, the Google Ads SEA agency in Paris, to learn more and boost your business by reaching the top of search results and the best positions on the display network and on Amazon!
