What is SEO?
SEO stands for "search engine optimization." It refers to the practice of optimizing your website and content to rank higher in organic (non-paid) search engine results for relevant keywords and phrases.
The goal of SEO is to increase your visibility on search engines like Google and drive more organic traffic to your site. The higher you rank, the more likely people are to find and visit your site.
Key SEO strategies include:
- Conducting keyword research to identify relevant, high-traffic search terms
- Optimizing on-page elements like title tags, meta descriptions, headers, and content
- Building high-quality backlinks from other reputable websites
- Improving technical factors like site speed, mobile-friendliness, and site architecture
- Creating valuable, search-optimized content that matches search intent
Important SEO metrics to track:
- Organic traffic
- Keyword rankings
- Backlinks
- Search visibility
- Organic conversion rate
The main advantage of SEO is that it delivers lasting results. Once you achieve high rankings, you can continue getting free, passive traffic over time. It‘s also arguably the best strategy for reaching people in the early stages of the buyer‘s journey when they are searching for information and solutions.
However, SEO also has some drawbacks. It can take a long time (6+ months) to see significant results. It‘s also becoming increasingly competitive, and there‘s no guarantee of reaching the top spots. You‘re ultimately at the mercy of search algorithms, which change frequently.
What is SEM?
SEM stands for "search engine marketing." While sometimes used as an umbrella term that includes SEO, SEM more commonly refers to paid search advertising, also known as pay-per-click (PPC) marketing.
With SEM, you pay to have your ads displayed in search results for selected keywords. You only pay when someone clicks your ad. Your ads can appear above or below the organic results.
The most popular SEM advertising platform is Google Ads. Microsoft (Bing) Ads is another major player.
Key SEM activities include:
- Bidding on target keywords
- Crafting compelling ad copy and calls-to-action
- Organizing campaigns by theme and goals
- Setting budgets and bids at the campaign, ad group, and keyword level
- Improving quality scores to lower costs
- Designing and optimizing landing pages for conversions
- Conducting A/B tests to optimize ad performance
The most important SEM metrics are:
- Impressions
- Clicks
- Click-through rate (CTR)
- Average cost per click (CPC)
- Conversion rate
- Cost per conversion
- Return on ad spend (ROAS)
The biggest advantages of SEM are speed and control. You can start getting targeted traffic within hours of launching a campaign. You have much more control over who sees your ads, as you can apply various demographic and behavioral filters. You also control how much you spend.
However, SEM traffic stops the second you stop paying. Click costs can also add up very quickly, especially in competitive industries. You may end up paying a lot for clicks that never convert.
SEO vs SEM: Key Similarities and Differences
Now that we‘ve covered the basics of SEO and SEM, let‘s directly compare them. Here are the main similarities:
Similarities
- Both aim to drive more traffic from search engines
- Both require researching and targeting relevant keywords
- Both involve optimizing for factors that search engines care about
- Both require ongoing testing, monitoring, and optimization to maximize results
Now here are the key differences to be aware of:
Differences
- SEO targets organic/natural results; SEM targets paid results
- SEO is "free" (other than time/labor); SEM costs money for each click
- SEO can take months to drive results; SEM can drive results in hours/days
- SEO results are more lasting; SEM results end when you stop paying
- SEO reaches a wider pool of searchers; SEM only reaches those you specifically target
- SEO gets more overall clicks; SEM gets a higher CTR from a more targeted audience
So which one is right for you? The short answer is: both! But the right mix depends on your specific situation and goals.
You should prioritize SEO if:
- You have a limited budget
- You‘re in it for the long haul and want lasting results
- You want to build authority and brand recognition in your industry
- You are mainly trying to reach people in the early stages of the buyer‘s journey
SEM is a better option if:
- You have a decent-sized budget to play with
- You want fast results for a time-sensitive offer or event
- You want your message to reach a hyper-targeted group of people
- You are mainly trying to drive conversions from high-intent searchers
The most successful digital marketers leverage both SEO and SEM together in a coordinated fashion. Use SEM to drive quick traffic and conversions while building your organic presence for the long term.
