Digital marketing frequently asked questions: SEO, advertising, social media and email

Digital marketing covers a broad spectrum of channels, tools and strategies — and it is not unusual for businesses that are just beginning to explore this space to have many questions about what each channel actually means, how it works, how much it costs and what results it can realistically deliver. Prolink has compiled the most common questions that clients ask at the beginning of a collaboration or during the research phase — about SEO, Google Ads campaigns, Facebook and Instagram advertising, TikTok advertising, social media management and email marketing — and answered them clearly and without unnecessary jargon. The goal of this FAQ is not to sell a service but to help every business make an informed decision about which channels make sense for its objectives, budget and industry.

SEO

What is SEO and why is it important for my business?

SEO — search engine optimization — is a set of activities that improves the visibility of a website in the organic results of search engines such as Google. Unlike paid advertising that stops delivering results as soon as the budget is turned off, SEO builds long-term presence that generates traffic without a direct cost per click — making it one of the most cost-effective acquisition channels in the long run. It is important for any business that wants to be found online at the moment when a potential customer is actively looking for a product, service or information relevant to that business.

How long does it take for SEO to start delivering results?

SEO is not a channel that delivers results overnight — for most projects, realistic expectations range from three to six months for the first visible movement in positions and traffic, while stable and sustainable organic growth builds over a longer period of six to twelve months and beyond. The speed of results depends on the initial state of the website, the competitiveness of the niche and the intensity of work invested — a new website in a competitive industry waits longer for results than an established site that simply needs technical optimisation.

What is the difference between on-page and off-page SEO?

On-page SEO refers to all optimisations carried out directly on the website — optimisation of titles, meta descriptions, content, internal link structure, page speed and technical correctness. Off-page SEO refers to activities outside the site itself, primarily link building — acquiring quality external references from authoritative websites that signal to search engines that the site is relevant and trustworthy. Both elements are essential for achieving and maintaining high organic positions, and there is a synergy between them — a technically sound website with quality content attracts external links far more easily.

What is local SEO and do I need it?

Local SEO is the optimisation of visibility for searches with local intent — when a user searches for "restaurant in London" or "hairdresser Manchester," Google displays locally relevant results. Local SEO is particularly important for businesses with a physical location or those that provide services in a specific geographic area — it includes optimisation of the Google Business profile, local citations and content tailored to local searches. For such businesses, local SEO often delivers the fastest and most directly measurable results of all SEO activities.

Can I do SEO myself or do I need an agency?

The basics of on-page optimisation can be mastered by any website owner willing to invest time in learning and implementation — optimising meta descriptions, titles and basic content structure is not reserved exclusively for specialists. However, technical SEO optimisation, link building and content strategy development require deeper knowledge, experience and tools that are difficult to replicate without prior practice — and it is precisely in these elements that agency support makes the greatest difference between average and excellent results.

Google Ads

What is Google Ads and how does it work?

Google Ads is the platform for paid advertising within the Google ecosystem — ads are shown to users who are actively searching for relevant keywords, making it a channel with exceptionally high purchase intent at the moment of ad display. The system operates on an auction principle — advertisers bid for positions on specific keywords and pay only when a user clicks on the ad. In addition to search campaigns, Google Ads includes display campaigns, shopping campaigns for e-commerce, video campaigns on YouTube and remarketing that shows ads to users who have already visited the website.

How much budget is needed for Google Ads?

There is no minimum budget that guarantees results — Google Ads works even with smaller budgets, but the scope and speed of testing are limited by available funds. For local campaigns with lower competition, meaningful starting budgets range from 300 to 500 EUR per month, while competitive industries and national campaigns require significantly more to achieve the statistical significance needed for optimisation. It is essential to distinguish between the ad budget — which goes directly to the platform — and the campaign management cost paid to an agency.

What is the difference between Google Ads and SEO?

Google Ads delivers immediate results — as soon as the campaign is activated, ads are displayed — but stops delivering results as soon as the budget is turned off. SEO is slower but builds a long-term presence that does not depend on daily spend. In practice, these two channels are not competitors but complements — Google Ads is ideal for quickly testing an offer and generating traffic while SEO is still growing, and SEO reduces dependence on paid traffic in the long run. Businesses that combine both channels most often achieve better overall results than those relying on just one.

What is remarketing and why is it important?

Remarketing — or retargeting — is the technique of showing ads to users who have already visited a website or interacted with a brand but have not converted. These users have a significantly higher likelihood of conversion than a completely cold audience because they have already shown interest, which means the cost per conversion is structurally lower. Remarketing campaigns are particularly valuable for e-commerce — a user who added a product to their cart but did not purchase is an excellent candidate for a remarketing ad with a reminder or a special offer.

How is the success of Google Ads campaigns measured?

The success of Google Ads campaigns is measured through a set of metrics defined according to the business objective — for e-commerce these are ROAS (return on ad spend) and cost per purchase, for lead generation cost per lead and form conversion rate, and for brand awareness reach and impression frequency. All metrics must be placed in the context of the business objective because a high CTR without conversions does not mean a successful campaign, and a high cost per click does not necessarily mean a bad campaign if conversions are profitable.

Facebook and Instagram advertising

Why advertise on Facebook if young people no longer use it?

Facebook retains a dominant position among the demographic group between 30 and 60 years of age — users who make the majority of purchasing decisions in households and business environments and who are harder to reach on platforms oriented towards younger audiences. Additionally, Facebook and Instagram share the same Meta advertising ecosystem, which means campaigns set up in Meta Ads Manager can automatically reach audiences on both platforms. For businesses whose target group is not teenagers, Facebook remains one of the most effective paid digital marketing channels.

What is the difference between Facebook and Instagram advertising?

Facebook and Instagram share the same advertising platform — Meta Ads Manager — but have different user demographic profiles, different formats and different content consumption logic. Instagram is a visually oriented platform with a younger demographic and an emphasis on creative quality, while Facebook has an older and broader demographic and works better for text-rich content and longer formats. In practice, campaigns are most often run simultaneously on both platforms with creative adapted to the format of each.

What are lookalike audiences and why are they useful?

Lookalike audiences are built by the Meta algorithm based on the characteristics of an existing audience that the advertiser defines as a source — most commonly existing customers, website visitors or users who completed a specific action. The algorithm finds users who statistically most resemble that source audience — meaning the cold audience towards which ads are served already has a high probability of interest in the offer. Lookalike audiences are one of the most effective tools for scaling campaigns towards new users without losing relevance.

How much budget is needed for Facebook advertising?

Facebook advertising works even with relatively small budgets — local campaigns with precise geographic targeting can deliver measurable results from as little as 200 to 300 EUR per month. However, testing different audiences, creatives and formats requires sufficient data, and small budgets limit the speed at which that data is collected. A general rule is that the minimum meaningful budget for each individual ad set is around 5 to 10 EUR per day — less than that does not give the algorithm enough signals for effective optimisation.

What are dynamic catalogue ads and who are they useful for?

Dynamic catalogue ads automatically generate personalised ads based on a product catalogue and show them to users according to their previous behaviour — a user who viewed a specific product sees an ad for exactly that product rather than a generic brand advertisement. They are particularly useful for e-commerce brands because they eliminate the need to manually create hundreds of different ads for different products while simultaneously ensuring high message relevance for each individual user.

TikTok advertising

Is TikTok relevant for my business if I am not targeting young people?

TikTok is no longer exclusively a platform for teenagers — the demographic profile of users is increasingly expanding towards the 25 to 40 segment, and in some markets towards older audiences as well. Relevance depends on the industry and target audience — FMCG brands, tourism, hospitality, e-commerce and lifestyle categories find on TikTok an audience that is actively engaged and open to discovering new products. B2B and highly competitive professional categories still have more limited reach to relevant audiences, but this is changing as the platform matures.

What are Spark Ads and how do they differ from standard ads?

Spark Ads are a format that allows boosting of existing organic content — whether the brand's own posts or creator content for which permission to boost has been granted — and showing that content as a paid ad to a precisely defined audience. Unlike standard In-Feed ads created exclusively for advertising purposes, Spark Ads retain the authenticity of organic video while combining all the advantages of precise paid targeting. The result is an ad that does not feel like an ad to the user — which on TikTok, where users have high tolerance for authentic content but low tolerance for advertising, makes a crucial difference.

Why does creative play a greater role on TikTok than on other platforms?

The TikTok algorithm distributes content primarily based on engagement signals — completion rate, likes, comments and shares — rather than based on the demographic profile of users or follower count. This means that an ad which fails to hold user attention within the first few seconds receives decreasing distribution regardless of budget, while an ad with high engagement signals is rewarded by the algorithm with increased distribution. Creative that works on TikTok must look like a natural part of the platform — a naturalistic style, vertical format and a hook within the first seconds that prevents scrolling are prerequisites that cannot be bypassed.

Social media management

What is included in a social media management service?

Social media management covers the complete set of activities needed to build and maintain an active and relevant presence on selected platforms — content strategy and planning, creation of visual and written content, publishing according to an optimal schedule, community management that includes responding to comments and messages, and analytics and reporting that tracks performance and provides direction for optimisation. Depending on the package, it can also include setup and management of paid advertising campaigns.

How many posts per week is optimal for my profile?

There is no universal answer because the optimal frequency depends on the platform, industry, content type and available production resources — more important than the number of posts is consistency and quality. On Instagram and Facebook, three to five posts per week is a sufficient rhythm for building organic reach, on LinkedIn two to three times per week delivers good results, while TikTok rewards a higher volume and more frequent publishing due to the way its algorithm distributes new content. Prolink defines the optimal frequency for each client based on objectives, audience and available content material.

Does my business need to be on all social media platforms?

No — presence on platforms that do not deliver value for a specific business simply consumes resources without measurable return. Platform selection should be based on where the target audience is located, what type of content the business can consistently produce and what business objective is to be achieved. A B2B business with limited resources is better served by consistent presence on LinkedIn than by diluted activity across five platforms of which four are irrelevant to its audience.

How is the success of social media management measured?

Success is measured through a combination of metrics that reflect different levels of value — reach and impressions indicate how many users saw the content, engagement rate measures how well the content resonated with the audience, follower growth tracks community building, while conversions and website traffic measure direct business impact. Prolink monitors all relevant metrics and delivers a monthly report that interprets data in the context of agreed business objectives — not merely as a set of unexplained numbers.

Email marketing

Is email marketing still relevant in the age of social media?

Email marketing is not only relevant but consistently records one of the highest returns on investment of all digital channels — the average ROI of email marketing far exceeds most other channels precisely because communication goes directly to people who have explicitly given permission to receive messages. Unlike social media where organic reach depends on an algorithm that continuously changes, an email list is a channel the business fully controls and whose reach does not depend on platform changes.

How do I build an email list from scratch?

Building an email list starts with a clear value that the subscriber receives in exchange for their address — a lead magnet such as a useful guide, discount, free sample or exclusive content is the most effective tool for initial contact collection. Pop-up forms on the website, landing pages for specific offers and sign-up forms on social media are standard channels for list growth. The key is that every subscriber on the list has an active interest in brand communication — a list of one thousand engaged subscribers is worth more than ten thousand passive ones who do not open messages.

What is email automation and how can it help me?

Email automation enables sending pre-defined messages to specific users at the right time, based on their behaviour or status in the buying process — welcome sequences for new subscribers, abandoned cart emails for e-commerce users, nurturing sequences for potential clients in a B2B sales process or reactivation campaigns for inactive subscribers. Automated email flows work continuously without manual intervention and ensure that no important touchpoint in the customer journey goes without relevant communication.

What is the optimal email open rate?

Average open rates vary significantly depending on industry, list type and contact collection method — industries such as B2B services, education and finance record higher open rates than e-commerce and mass communications. As a rough reference point, an open rate above 20 percent is considered a solid average for most industries, while segmented and personalised campaigns to highly engaged lists often achieve 35 to 50 percent. More important than the absolute open rate is the trend over time — whether it is falling, stagnating or growing.

How do I avoid emails ending up in the spam folder?

Email deliverability depends on a combination of technical and content factors — technically, proper configuration of SPF, DKIM and DMARC records for the sending domain is the foundation without which even the best content does not reach the inbox. In terms of content, avoiding spam trigger words, consistent sending frequency, cleaning the list of inactive subscribers and high engagement from users who receive messages are signals that email providers use to assess sender reputation. Purchased lists and mass sending to contacts who have not given permission are the surest path to deliverability penalties.

How is the success of email campaigns measured?

The key metrics of email marketing are open rate which shows what percentage of recipients open the message, click-through rate which measures what percentage click on content within the email, conversion rate which tracks how many clicks result in the desired action, and unsubscribe rate which signals how relevant the content is to recipients. For e-commerce campaigns, revenue generated from emails is directly tracked, while for B2B lead generation the number of qualified enquiries coming from the email channel is monitored. Each metric only makes sense in the context of the specific campaign objective — a newsletter that educates has different benchmark values from a promotional campaign with a time-limited offer.

General questions about digital marketing

Which digital channel is best for my business?

There is no universally best channel — the right choice depends on the industry, target audience, budget, sales cycle and the objectives the business wants to achieve. E-commerce brands most often benefit from a combination of Google Shopping, Meta advertising and email marketing, B2B businesses from SEO, LinkedIn advertising and email nurturing, and local businesses from local SEO, Google Ads and Facebook advertising. Prolink recommends starting from the audience — where it is located and how it makes decisions — rather than from channels that are currently popular.

How do I set realistic expectations from digital marketing?

Digital marketing is not a magic generator of instant results — different channels have different timeframes for visible movement, different learning curves and different cost structures. Paid channels such as Google Ads and Meta advertising can start generating results relatively quickly but require a testing and optimisation phase that has a cost. SEO and email marketing build value more slowly but more durably. Realistic expectations are built through understanding these differences and through setting goals aligned with budget, timeframe and industry specifics.

Do I need an agency or an in-house team for digital marketing?

Both models have their advantages and limitations — an in-house team deeply understands the business and its products, is available for quick communication and does not divide attention among other clients. An agency brings a broader range of competencies, experience gained from working with different industries and clients, and access to specialised tools and knowledge that would be too costly to build in-house. A hybrid model — an in-house coordinator working with agency partners for specific channels — is often the most optimal for medium-sized businesses that need both depth of brand knowledge and breadth of specialised expertise.
