SEO stands for “search engine optimization.” In simple terms, SEO means the process of improving your website to increase its visibility in Google, Microsoft Bing, and other search engines whenever people search for:
- Products you sell.
- Services you provide.
- Information on topics in which you have deep expertise and/or experience.
The better visibility your pages have in search results, the more likely you are to be found and clicked on. Ultimately, the goal of search engine optimization is to help attract website visitors who will become customers, clients or an audience that keeps coming back.
How is SEO different from SEM and PPC?
SEM and PPC are two other common terms you will read about a lot here on Search Engine Land and hear about in the larger search marketing community.
Read on to learn more about both of these terms and how they’re related to SEO.
SEO vs. SEM
SEM stands for search engine marketing – or, as it is more commonly known, search marketing.
Search marketing is a type of digital marketing. It is an umbrella term for the combination of SEO and PPC activities meant to drive traffic via organic search and paid search.
Put simply, search marketing is the process of gaining traffic and visibility from search engines through both paid and unpaid efforts.
So how do SEO and SEM differ? Technically they aren’t different – SEO is simply one-half of SEM:
- SEO = driving organic traffic from search engines.
- SEM = driving organic and paid traffic from search engines.
Now, this is where things get a bit confusing.
Today, many people use SEM interchangeably with PPC (which we’ll talk about in the next section).
This idea seems to undercut SEO. However, SEO is marketing, just like PPC is marketing.
Here’s the best way to think about SEO and SEM:
Imagine SEM is a coin. SEO is one side of that coin. PPC is on the flip side.
SEO vs. PPC
PPC stands for pay-per-click – a type of digital marketing where advertisers are charged whenever one of their ads gets clicked on.
Basically, advertisers bid on specific keywords or phrases that they want their ads to appear for in the search engine results. When a user searches for one of those keywords or phrases, the advertiser’s ad will appear among the top results.
So again, if we think of search marketing as a coin, SEO and PPC are two sides of the same coin – SEO is the unpaid side, PPC is the paid side.
Another key point: it’s important never to think of it as “SEO vs. PPC” (i.e., which one is better) because these are complementary channels. It’s not an either-or question – always choose both (as long as your budget allows it).
As we mentioned before, the terms SEM and PPC are used within the industry interchangeably. However, that isn’t the case here on Search Engine Land.
Whenever we mention “SEM,” it will be because we’re referring to both SEO (organic search) and PPC (paid search).
If you’re curious about the history behind how “SEM” came to mean “PPC” at the exclusion of SEO, you can dig deeper into these articles:
Why is SEO important?
If you found this page via Google search, you likely searched Google for [what is seo] or [seo].
This guide is published on Search Engine Land, an authoritative website with great expertise on and experience in the topic of SEO (we’ve been covering all SEO changes, big and small since 2006).
Originally published in 2010, our “what is SEO” page has earned a whopping 324,203 links.
Put simply, these factors (and others) have helped this guide earn a good reputation with search engines, which has helped it rank in Position 1 for years. It has accumulated signals that demonstrate it is authoritative and trustworthy – and therefore deserves to rank when someone searches for SEO.
But let’s look at SEO more broadly. As a whole, SEO really works through a combination of:
- People: The person or team responsible for doing or ensuring that the strategic, tactical and operational SEO work is completed.
- Processes: The actions taken to make the work more efficient.
- Technology: The platforms and tools used.
- Activities: The end product, or output.
Many other things factor into how SEO works. What follows is a high-level look at the most important knowledge and process elements.
Six critical areas, in combination, make SEO work:
1. Understanding how search engines work
Simply, if you want people to find your business via search – on any platform – you need to understand the technical processes behind how the engine works – and then make sure you are providing all the right “signals” to influence that visibility.
When talking about traditional web search engines like Google, there are four separate stages of search:
- Crawling: Search engines use crawlers to discover pages on the web by following links and using sitemaps.
- Rendering: Search engines generate how the page will look using HTML, JavaScript and CSS information.
- Indexing: Search engines analyze the content and metadata of the pages it has discovered and add them to a database (though there’s no guarantee every page on your website will be indexed).
- Ranking: Complex algorithms look at a variety of signals to determine whether a page is relevant and of high-enough quality to show when searchers enter a query.
But optimizing for Google search is different from optimizing for search other platforms like YouTube or Amazon.
Let’s take Facebook, for example, where factors such as engagement (Likes, comments, shares, etc.) and who people are connected to matter. Then, on Twitter, signals like recency, interactions, or the author’s credibility are important.
And further complicating things: search engines have added machine learning elements in order to surface content – making it even harder to say “this” or “that” resulted in better or worse performance.
2. Researching
Research is a key part of SEO. Some forms of research that will improve SEO performance include:
- Audience research: It’s important to understand your target audience or market. Who are they (i.e., their demographics and psychographics)? What are their pain points? What questions do they have that you can answer?
- Keyword research: This process helps you identify and incorporate relevant and valuable search terms people use into your pages – and understand how much demand and competition there is to rank for these keywords.
- Competitor research: What are your competitors doing? What are their strengths and weaknesses? What types of content are they publishing?
- Brand/business/client research: What are their goals – and how can SEO help them achieve those goals?
- Website research: A variety of SEO audits can uncover opportunities and issues on a website that are preventing success in organic search. Some audits to consider: technical SEO, content, link profile and E-E-A-T.
- SERP analysis: This will help you understand the search intent for a given query (e.g., is it commercial, transactional, informational or navigational) and create content that is more likely to earn rankings or visibility.
3. Planning
An SEO strategy is your long-term action plan. You need to set goals – and a plan for how you will reach them.
Think of it your SEO strategy as a roadmap. The path you take likely will change and evolve over time – but the destination should remain clear and unchanged.
Your SEO plan may include things such as:
- Setting goals (e.g., OKRs, SMART) and expectations (i.e., timelines/milestones).
- Defining and aligning meaningful KPIs and metrics.
- Deciding how projects will be created and implemented (internal, external or a mix).
- Coordinating and communicating with internal and external stakeholders.
- Choosing and implementing tools/technology.
- Hiring, training and structuring a team.
- Setting a budget.
- Measuring and reporting on results.
- Documenting the strategy and process.
4. Creating and implementing
Once all the research is done, it’s time to turn ideas into action. That means:
- Creating new content: Advising your content team on what content needs to be created.
- Recommending or implementing changes or enhancements to existing pages: This could include updating and improving the content, adding internal links, incorporating keywords/topics/entities, or identifying other ways to optimize it further.
- Removing old, outdated or low-quality content: The types of content that aren’t ranking well, driving converting traffic or helping you achieve your SEO goals.
5. Monitoring and maintaining
You need to know when something goes wrong or breaks on your website. Monitoring is critical.
You need to know if traffic drops to a critical page, pages become slow, unresponsive or fall out of the index, your entire website goes offline, links break, or any other number of potential catastrophic issues.
6. Analyzing, assessing and reporting on performance
If you don’t measure SEO, you can’t improve it. To make data-driven decisions about SEO, you’ll need to use:
- Website analytics: Set up and use tools (at minimum, free tools such as Google Analytics, Google Search Console and Bing Webmaster Tools) to collect performance data.
- Tools and platforms: There are many “all-in-one” platforms (or suites) that offer multiple tools, but you can also choose to use only select SEO tools to t
- ack performance on specific tasks. Or, if you have the resources and none of the tools on the market do exactly what you want, you can make your own tools.
After you’ve collected the data, you’ll need to report on progress. You can create reports using software or manually.
Performance reporting should tell a story and be done at meaningful time intervals, typically comparing to previous report periods (e.g., year over year). This will depend on the type of website (typically, this will be monthly, quarterly, or some other interval),
SEO is ongoing
SEO never ends. Search engines, user behavior and your competitors are always changing. Websites change and move (and break) over time. Content gets stale. Your processes should improve and become more efficient.
Bottom line: There’s always something you can be monitoring, testing or improving. Or, as Bruce Clay put it: SEO will only be done when Google stops changing things and all your competition dies.
