SEO Glossary: Terms, Tactics and Services Explained
Search marketing has its own vocabulary, and much of it is used loosely. A proposal may promise “technical SEO” or “funnel optimization” without explaining what either means for your business. This glossary defines the terms you are most likely to meet when you hire help or review a report, in plain language.
Each entry explains what the term means and why it matters, so you can ask better questions rather than accept a label. Bobs SEO is the brand behind this resource, and the definitions here are written to be useful whether you work with us or handle the work yourself.
The terms are grouped by the part of a campaign they belong to. You can read straight through, or jump to the section that matches a question you are trying to answer.

Research, Market and Audience Analysis
Before any campaign starts, research decides what the work should be. These terms cover how a team studies a market, a competitor set, and the people it wants to reach.
Market analysis
Market analysis is the study of demand, competitors, and pricing within a business category. It answers whether a service is worth pursuing before any optimization work begins.
Competitor analysis
Competitor analysis reviews which pages, keywords, and offers competing businesses use in search results. It shows where a business can realistically win visibility instead of chasing the same terms as everyone else.
Niche marketing
Niche marketing focuses a campaign on a narrow, well-defined audience rather than a broad market. In search, that usually means fewer keywords with clearer intent and less competition.
Target audience
A target audience is the group a campaign is built to reach. In search it is defined by what those people type, where they are located, and what they need before they contact a business.
Audience targeting
Audience targeting narrows ads and content to specific groups based on location, interests, or behavior. It keeps budget and effort on the people most likely to convert.
Keyword research
Keyword research is the work of finding the searches a business can realistically rank for, then mapping each one to a page. It is the foundation for every other optimization decision.
Long-tail keywords
Long-tail keywords are longer, more specific search phrases with lower volume and clearer intent. They often convert better than broad terms because the searcher already knows what they want.
Keyword density
Keyword density is how often a phrase appears relative to the rest of a page. Modern ranking systems reward natural, useful writing, so density is a diagnostic rather than a number to hit.
Ranking factors
Ranking factors are the signals search engines weigh when ordering results, including relevance, content quality, page experience, and links. No single factor guarantees a position.
On-Page, Technical and Website Optimization
On-page and technical work makes a site easy for search engines to read and easy for people to use. These are the terms that appear in almost every audit.
On-page SEO
On-page SEO covers everything on a page itself: headings, copy, internal links, images, and structured data. It is the part of optimization a business controls most directly.
Title tags
A title tag is the page title shown in search results and browser tabs. It should state what the page offers in plain language and stay within a readable length.
Meta tags
Meta tags are code in a page’s head that describe it to browsers and search engines. The meta description often becomes the snippet text, though search engines may rewrite it.
URL structure
URL structure is how a site’s addresses are organized. Short, readable, stable URLs help people and search engines understand what a page is about.
Site architecture
Site architecture is the way pages are grouped and linked. Clear architecture helps visitors move from general information to a specific service, and helps crawlers find every important page.
Image optimization
Image optimization means compressing and formatting images so pages load quickly without losing quality. It also includes descriptive file names and alt text.
Page speed
Page speed is how quickly a page becomes usable. Slow pages lose visitors and can be held back in results, so speed is routine technical work rather than a one-time fix.
Mobile optimization
Mobile optimization makes a site easy to read and use on a phone. Because most local searches happen on mobile, this is often the highest-impact fix available.
Responsive design
Responsive design means one layout adapts to any screen size instead of maintaining separate mobile and desktop sites. It keeps content and links consistent across devices.
Hosting services
Hosting services provide the server a website runs on. Slow or unreliable hosting undermines every other improvement, which is why server response time is checked during an audit.
Optimization techniques
Optimization techniques are the specific methods used to improve a page or site, from rewriting headings to repairing redirects. The right set depends on what an audit finds.
Usability testing
Usability testing observes real people attempting a task on a site. It reveals friction that analytics alone cannot explain, such as a confusing form or an unclear menu.
User experience
User experience is how easy and pleasant a site is to use. Search systems weigh page experience signals, so usability and visibility are connected rather than separate projects.
Unique content
Unique content is material written for a specific page and audience rather than copied or spun from another source. Duplicate pages compete with each other and rarely earn trust.
Content, Links and Authority
Authority is earned by publishing material worth citing and by making it easy for others to cite it. These terms describe that work. For the production side, see how a content creation firm fits alongside link building.
Content marketing
Content marketing is the ongoing creation of useful material — guides, comparisons, answers — that attracts an audience and supports search visibility. It works best when it answers questions people actually ask.
Guest blogging
Guest blogging is writing an article for another publication. Done honestly it earns a relevant link and exposure; done at scale purely for links, it adds little value.
Link building
Link building is the work of earning links from other websites to pages that deserve them. Relevant, editorially given links remain one of the strongest trust signals available.
Backlink strategy
A backlink strategy is the plan for which pages need links, what kind of sites should link to them, and how those links will be earned. Without a plan, outreach becomes random.
High-quality backlinks
High-quality backlinks come from relevant, credible sites and point to a page that genuinely answers a question. Quantity matters far less than relevance and editorial intent.
Outreach campaigns
Outreach campaigns are organized efforts to contact publishers, journalists, or partners about a resource worth linking to or covering. Specific, personal messages outperform bulk templates.
Negative SEO
Negative SEO refers to attempts to harm another site’s rankings, such as building spam links to it. Search engines are generally good at ignoring these attacks, and monitoring is the practical response.
White hat SEO
White hat SEO means following search engine guidelines: earning visibility with useful content, sound technical work, and genuine links. It is slower than shortcuts and far more durable.
Domain authority
Domain authority is a third-party score estimating how strong a site’s link profile is. It is a comparative benchmark for planning, not a metric search engines use directly.
Local Search, Geo-Targeting and Reputation
Local visibility depends on accurate listings, genuine reviews, and pages that match where a customer is searching. For a city-level example, see Las Vegas SEO services.
Local SEO
Local SEO is optimization aimed at searches with geographic intent, such as a service near a specific city. It combines listings, reviews, local content, and a crawlable website.
Geo-targeting
Geo-targeting delivers content or ads to people in a defined area. In local search it shapes which pages and listings appear for nearby searchers.
Google My Business
Google My Business, now called the Google Business Profile, is the listing that powers a company’s appearance in Maps and local results. Accurate categories, hours, and photos matter more than keyword stuffing.
Business listings
Business listings are the profiles carrying a company’s name, address, phone number, hours, and services across the web. Consistent listings help search engines confirm a business is real and local.
Directory submissions
Directory submissions place a business’s details in online directories. Consistent listings support local visibility; low-quality directories add noise rather than value.
Reputation management
Reputation management is the work of monitoring and responding to what customers say publicly, and of making sure accurate information appears when someone searches a brand.
Expert reviews
Expert reviews are evaluations written by people with relevant knowledge of a service or category. They help buyers compare providers, provided the reviewer discloses any relationship.
Paid Media, Social and Influencer Marketing
Search rarely works alone. These are the paid and social terms that come up when a campaign spans several channels. A digital marketing strategist usually decides how they fit together.
Pay-per-click
Pay-per-click is advertising where a business pays each time someone clicks an ad. It produces immediate traffic and is often paired with organic search work.
AdWords management
AdWords management is the day-to-day work of running Google Ads campaigns: structure, bids, keywords, negative keywords, and reporting. AdWords is the former name of Google Ads.
Facebook ads
Facebook ads are paid placements on Meta platforms, targeted by audience, interest, and behavior. They are commonly used for awareness and lead generation alongside search.
Social media marketing
Social media marketing is the use of social platforms to build audience and engagement. It supports brand awareness and can feed traffic to pages that convert.
Hashtag strategy
A hashtag strategy is a plan for which tags to use so content reaches the right communities. It matters most on platforms where discovery depends on tags.
Influencer marketing
Influencer marketing is partnering with people who have an engaged audience to present a product. Fit and clear disclosure matter more than follower count.
Affiliate marketing
Affiliate marketing pays partners a commission for sales or leads they refer. It extends reach without upfront media spend but requires clear tracking and terms.
Viral marketing
Viral marketing is content designed to be shared widely at little cost. It can produce a spike in attention, though spikes are hard to plan and rarely sustain demand.
Word-of-mouth marketing
Word-of-mouth marketing encourages customers to recommend a business. Online, reviews and referrals are its most visible form.
Brand awareness
Brand awareness is how familiar an audience is with a company. Search visibility builds it gradually, because repeated appearances create recognition before a click.
Analytics, Measurement and Reporting
Measurement is what separates a campaign from a guess. These terms describe how results are tracked, and how to tell whether the numbers mean anything.
Web analytics
Web analytics is the measurement of how people find and use a website. It turns traffic into evidence about which pages and channels actually produce inquiries.
Analytics tools
Analytics tools collect and report on site and campaign performance. The tool matters less than whether the metrics tie back to business outcomes.
Data analysis
Data analysis is the work of interpreting measurements to find patterns and causes. In SEO it answers which changes moved traffic and which made no difference.
KPI tracking
KPI tracking is the routine monitoring of the few numbers that define success, such as qualified leads or revenue from organic search. Tracking keeps reporting honest.
Performance metrics
Performance metrics are the measurements used to judge a campaign, from rankings to conversion rate. Choosing them before work begins prevents after-the-fact storytelling.
Engagement metrics
Engagement metrics describe how people interact with content, such as time on page, scroll depth, and clicks. They help explain why some pages convert and others do not.
Bounce rate optimization
Bounce rate optimization is the work of keeping visitors from leaving immediately. Clearer headings, faster pages, and matching the promise of the search result all reduce early exits.
Conversion rate
Conversion rate is the share of visitors who complete a desired action, such as a call or form submission. Improving it often beats chasing more traffic.
Click-through rate
Click-through rate is the share of people who see a result or ad and click it. In search it reflects how well a title and description match intent.
Referral traffic
Referral traffic arrives from a link on another site. It shows which publications and partners actually send visitors, not just which ones link.
Traffic analysis
Traffic analysis breaks visits down by source, page, and behavior. It separates useful visitors from volume that will never convert.
Position tracking
Position tracking monitors where pages rank for chosen keywords over time. It is a trend indicator, since results vary by location, device, and personalization.
Heatmaps analysis
Heatmaps analysis visualizes where people click, scroll, and pause on a page. It exposes sections visitors never reach, which is often why a page underperforms.
Funnel optimization
Funnel optimization is improving each step between first visit and completed inquiry. Finding the step where people drop off is usually more valuable than adding more traffic.
Follow-up strategies
Follow-up strategies are the sequences used after an inquiry, such as a call, email, or reminder. Search can deliver a lead that a slow follow-up loses.
Growth, Automation and Emerging Search
Search keeps changing, and so does the vocabulary around it. These terms cover newer tactics and the technology behind how results are produced.
Growth hacking
Growth hacking is rapid, experiment-driven marketing focused on one measurable metric at a time. It suits early-stage testing more than steady local visibility work.
Marketing automation
Marketing automation uses software to send emails, score leads, and trigger follow-ups. It keeps prospects engaged after the first visit without manual effort.
Inbound marketing
Inbound marketing attracts prospects with useful content instead of interrupting them with ads. Search optimization is usually its largest component.
Interactive content
Interactive content invites participation, such as calculators, quizzes, or assessments. It earns attention and links when it solves a real problem rather than decorating a page.
Visual content
Visual content communicates with images, diagrams, and video rather than text alone. It helps explain complex services and performs well on social platforms.
Video marketing
Video marketing uses video to explain, demonstrate, or promote. Short vertical video now drives discovery on search and social alike.
Natural language processing
Natural language processing is the technology that lets machines interpret human language. It underpins how search engines understand questions rather than isolated keywords.
Knowledge graph
A knowledge graph is a structured map of entities and their relationships. It is how search engines connect a business, its location, and its services to a query.
Featured snippets
Featured snippets are the summarized answers shown above standard results. They are earned by pages that answer a question clearly and concisely.
Network analysis
Network analysis studies relationships between sites, pages, or audiences to find influence and gaps. In link work it helps identify which sources actually matter.
E-commerce and Conversion-Focused SEO
Online stores face a different set of problems from service businesses: large catalogs, filtered URLs, and product pages that must both rank and sell. Stores should start with ecommerce SEO services.
E-commerce SEO
E-commerce SEO is optimization for online stores: category pages, product pages, filters, and crawl efficiency. Large catalogs need a deliberate plan for which pages should rank.
Landing pages
Landing pages are built for a single action, such as a quote request or a purchase. Focused pages usually convert better than sending every visitor to a general homepage.
