The Definition of SEO in 100 Words or Less [FAQs]

Search engine optimization (SEO) seems pretty straightforward. You pick a few keywords, and voilà! Your page is optimized for SEO, right?

Not yet.

Many people understand the basic principles of SEO, but a lot has changed in the last decade.

The SEO that we know and love today is not the same SEO that we knew and loved (or hated) 10 years ago. And that's why SEO is something marketers should continue to define, and redefine. Here's a brief definition in under 100 words:

What Is SEO?

SEO stands for search engine optimization -- that much has stayed the same. It refers to techniques that help your website rank higher in search engine results pages (SERPs). This makes your website more visible to people who are looking for solutions that your brand, product, or service can provide via search engines like Google, Yahoo!, and Bing.

What hasn't stayed the same are the techniques we use to improve our rankings. This has everything to do with the search algorithms that these companies constantly change.

Here are some other frequently asked questions about this critical practice today.

Looking deeper: There are a ton of ways to improve the SEO of your site pages, though. Search engines look for elements including title tags, keywords, image tags, internal link structure, and inbound links (also known as backlinks). And that's just to name a few.

HubSpot customers: you can check out the SEO panel in your HubSpot account to see how well you're optimized for those things.

Search engines also look at site structure and design, visitor behavior, and other external, off-site factors to determine how highly ranked your site should be in their SERPs.

Looking deeper: In present-day SEO, you can't simply include as many keywords as possible to reach the people who are searching for you. In fact, this will actually hurt your website's SEO because search engines will recognize it as keyword stuffing -- or the act of including keywords specifically to rank for that keyword, rather than to answer a person's question.

Nowadays, you should use your keywords in your content in a way that doesn't feel unnatural or forced. There isn't a magic number -- it all depends on the length of your keyword and article -- but if you feel like you're forcing it, it's better to ignore it and continue writing naturally.

Looking deeper: Before you create a new site page or blog post, you'll probably be thinking about how to incorporate your keywords into your post. That's alright, but it shouldn't be your only focus -- or even your primary focus. Whenever you create content, your focus should be on the intent of your audience, not how many times you can include a keyword (whether it's long tail or short tail) in your content.

To satisfy intent and rank well in the long term, build your SEO marketing strategy around topics, not keywords. If you do that, you'll find you can naturally optimize for important keywords, anyway. Understanding your target audience (aka buyer personas) and what interests them is key to attracting relevant visitors to your website through search engines. You can also hire contractors or outsource SEO to digital marketing and SEO agencies.

Looking deeper: One of the biggest changes in the last decade is the way other user behaviors shape the SERPs a user sees on search engines. And today, social media can have a big impact on your organic traffic trend line. Even just a few years ago, it didn't make a difference who was finding your content through social search. But now SEO takes into account tweets, retweets, Google+ authorship, and other social signals.

Social search also prioritizes content and people that are connected to you. That could mean through a Facebook friend, Twitter follower, or connection through another social network. Sometimes social search will even prioritize content that has been shared by an influencer. Social search understands that you may be interested in content that your network feels is important to share, and therefore it'll often get surfaced to you.

This all means when you're thinking about your SEO strategy, you need to think about how your social media strategy fits into the puzzle, too.

Looking deeper: Think of search engine optimization as "search experience optimization." It's not just important for your users to find your website -- it's important for them to stay on your website, interact with your content, and come back later. Direct traffic doesn't just increase your "page authority" in the eyes of Google; it creates more opportunities to turn someone, who first discovered you organically, into a customer.

SEO actually takes into account whether or not your visitors are staying on your website and engaging with other content. If you rank well for a keyword and attract a visitor who isn't relevant, it won't actually help your website.

Think about your visitors and the content they are looking for more than how many people you can attract to your website.

Looking deeper: In the past, SEO success was measured by whether or not you were ranked high on the first page of Google. But even if you ranked well for a term, does that actually mean you're going to see results?

Not always. You might rank really well for terms that aren't ideal for your business. So you appear high on search engines, get a ton of traffic, but then your website visitors realize your company isn't what they were looking for. You don't convert customers from this traffic, and ranking high for this particular keyword is essentially fruitless.

Also, you don't necessarily need to be in the top three slots to be successful. In fact, if you rank well on subsequent pages, you may still have a high clickthrough rate, albeit less traffic. That's great news for marketers who can't seem to bring pages into those top slots or off the second page.

We said it before and we'll say it again: The amount of traffic to your page is less important than how qualified that traffic is.

Looking deeper: An SEO cost can mean one of two things: the investment in your organic search strategy, or how much you pay for paid search engine marketing (SEM) services like Google AdWords. If you're paying for a tool, SEO checker, consultant, or marketing agency to help you optimize your web content, your bill can vary wildly with the depth of the services you're receiving.

Yes, $10,000 sounds scary, but 40% of businesses today are actually spending less than $1,000 a month on SEO. You can also learn to do SEO yourself by taking an SEO course or by reading on different strategies and best practices online.

Looking deeper: You can actually pay for top rankings on Google SERPs by registering for a free account on Google AdWords. You'll then select various keywords you'd like to rank under, and pay Google each time a user clicks on your result. This is called PPC search engine marketing, and your ads will be noticeably different in their appearance than the organic results below them.

The average cost of a paid search campaign on Google can be less than $1 per click, but, naturally, the more popular the keyword, the more you might pay.

It's still the same thing it was 10 years ago -- a bunch of tactics that, if you employ them, will help you rank better in search engines. It's just the tactics we now use that have changed. If you're new to SEO or would like a refresher course, you might be interested in our free SEO training.

It's up to us to stay on top of the rapidly changing trends, and remember that ultimately, the goal of search engines is to deliver the best experience possible to their end-user -- searchers. If you keep that goal in mind with your SEO strategy, you'll find your choices pay off, even if you're not totally up to date on every single nuance of search engine algorithms.
