Link Relationship

<a> tags can have the rel attribute applied to outbound links, that helps browsers and search engines understand the relationship your website has with the link.

The three most relevant values are:

Generally speaking, you would mark links to external sites you don't fully endorse with nofollow, links where you stand to gain monetarily as sponsored, and have all links by users as ugc.

Links to sites that you fully trust, but don't gain money for linking to, are free to be without a rel attribute.

Note: You can apply multiple values to the rel attribute, such as rel="ugc nofollow".

Note: The attributes noopener and noreferrer can be used to prevent the website you link to from knowing where the link came from.

Usability

A SEO term based on "user experience first" design.

When creating websites, it is important to take the user experience into account, and keep it at the centre of your entire process. A great user experience will lead to more time spent on your website, lower bounce rates and higher conversions.

It is important to keep these three things in mind:

PageRank

Both a SEO term and an algorithm created by Google for ranking pages.

While your pages official PageRank score can no longer be obtained, as Google retired the official testing tool in 2016, most SEO tools like Ahrefs, Semrush and many more, create their own version of PageRank, usually in an effort to attribute a weighted value of authority to a website or domain.

PageRank, the algorithm, appears to still be in use to this day, likely still using inbound and outbound links, and the PageRank of those pages, to weigh and rank pages across the internet.

Note: If you would like to read the original 1997 paper on the algorithm, written by Google founders Sergey Brin and Larry Page, you can find it on Stanford University's website: The Anatomy of a Large-Scale Hypertextual Web Search Engine.

Organic Search Results

Results provided by a search engine, based on a search query.

Organic results are the results returned based solely on the websites ranking factors and their SEO efforts, as opposed to the Ads often found as the first set of links.

As an example, Google searches often include Ads powered by their own ads platform; Google Ads. These are paid for, and are not part of the organic results.

Link Building

The practice of getting inbound links to your website from other websites.

Link building is getting links from business listings, reaching out to bloggers, reviewers, journalists and other relevant websites.

Backlinks help improve the authority of your site, and can have a significant impact on how well you rank in organic search.

Note: For back linking to work effectively, you need content worth linking to. Having a thousand back links from local business registrars will have very little effect, but getting a reviewer or blogger to write about your product or services, linking directly to them, will help immensely.

Site Map

A site map is complete list of all pages within a whole website.

These site maps are often formatted as an XML file, structured in a way to help web crawlers easily find all pages to look through.

XML site maps can be styled with CSS, in order to be more both more visually pleasing, but also much more readable to humans.

Some websites also include a dedicated page for a human-friendly overview of the entire site.

Site maps are critical to SEO.

Meta Tags

<meta> tags are elements of your HTML code that provide structured meta data and information about the page.

Some of this can be used by search engines, the "description" meta tag for instance will be used to fill the the text snippet in search results. You don't strictly speaking have to fill out a description tag, but it is highly recommended. Having an enticing description will improve your click-through rate, resulting in more conversions!

Note: Search engines limit how long of a text snippet they're willing to present. Google limits this at ~160 characters, or a pixel length of ~940px. Good SEO tools for WordPress (like SEOPress and Rank Math) will let you know if you exceed either.

Example:

<meta name="description" content="Northrook is delivering high-quality Web Design, Marketing, SEO and Hosting services to businesses, charities and beyond." />

Title Tag

The <title> tag is a HTML element that browsers and search engines use to determine the title of a given page.

You would typically be using a phrase built around one or more of your most valuable keywords, likely along with your brand or site name.

Example:

<title>Web Design, Ads, SEO Agency Southampton • Northrook</title>

Note: Most search engines, including Google and Bing, have a limit on how long of a title they're willing to display. This is typically around ~60 characters, or a pixel length of ~560px. Good SEO tools for WordPress (like SEOPress and Rank Math) will let you know if you exceed either.

Broken Link

A link that directs to a page or content that no longer appears to exist.

Errors like 404, various server errors and even changed URLs can lead to broken links.

Many SEO tools offer scans to look for broken links. Make sure to keep an eye on any broken links, and to fix or replace them as soon as possible, as they can negatively impact both your link profile and directly affect your search engine rank.

Click-through rate

The ratio of users who successfully click on a specific link, compared to the total number of users who have received or seen the link, often used to measure the relative success of a Call to Action link on a website, other online marketing and the like.

You can technically calculate a CTR on every link on your website, but choosing which ones to monitor is important. You don't want to miss valuable data, but you also don't want to receive so much data it becomes meaningless.

Call to Action

A link on your website, typically styled to attract the visitors eye, designed to further a specific action.

These actions commonly include; purchase intent, reading more about a key product or feature, sign-ups to product feeds or newsletters.

Basically the main thing you would like your visitors to click on.

Call to Action elements should be tracked with your analytics tool of choice, so you can determine how successful it is.

Branded Keywords

A set of keywords that directly include a business or brand name.

These are often less competitive, but rely on brand awareness to be effective.

Algorithm

An algorithm is by definition "a finite sequence of well-defined instructions, typically used to solve a class of specific problems", in the case of SEO, that problem is website ranking.

When most SEO professionals refer to "the algorithm" or "Googles algorithm", we're typically talking about the math behind Google's (and others) ranking factors.

These algorithms take the data gathered by millions of web crawls, look at all the data points and calculate page ranking based on those and several other factors, like backlinks and domain authority.

Google has a whole page dedicated to talking about how their algorithm works, should you wish to learn more.

Crawl

A third party looking through your website for content, such as pages, images, and other files.

These are typically performed by search engines like Google and Bing for indexing purposes, and other applications like SEO and performance tools, for testing and validating page content.

Web Crawlers

A web crawler is a type of automated script that "crawls" the web, looking at pages, images and other content, usually run by search engines like Google and Bing, to find and index your content. These automated scripts, often referred to as a "bot", can technically be run by anyone.

SEO and performance tools like Ahrefs, SEObility, Morningscore, and many more, use web crawlers for many purposes such as testing page performance, detecting index status, finding page relationships and more.

Most crawlers identify themselves when crawling a site.

You can use a robots.txt file on your server to manage which folders and file types bots are supposed to look for.

Analytics

A system for gathering visitor data and statistics.

The most commonly used analytics tool is Google Analytics. Google's analytics tools come in a few flavours, the modern "Google Analytics 4" and venerable "Universal Analytics".

Google's approach gathers lots of information, and will in most cases violate GDPR, requiring you to gain visitor consent before you can start tracking. It is also vulnerable to ad-blockers, as they may entirely block the code from running.

There are several GDPR and privacy friendly alternative tracking tools, like Plausible Analytics or Matomo.

We recommend using Plausible, and offer it as part of our AfterCare packages.

Plausible offers largely the same metrics as Universal Analytics, but can be made resilient to ad-blockers and other tracking blockers, due to it not gathering a single identifiable marker.

Tips:

Link Profile

A SEO term for all the links pointing to your website. How good or bad a link profile is, will depend on both the relative value of the back links to your website, and the judgement of the SEO specialist that review it.

Generally speaking a balanced profile is a good profile, that means having a good deal of quality back links from high authority sites in your niche, such as reviews linking to a product type or an article citing you as a trusted source, along with several back links from mentions on local business registrars, blog posts and the like.

Poor link profiles typically only have links from low authority sites, and may have several broken inbound links.

Algorithm Penalty

A penalty applied directly to the ranking of certain pages with certain keywords, typically after a breach of Google's guidelines.

It can be difficult to detect when you've been penalised, as most actions are taken quietly. Best way to notice is to keep an eye on your traffic, and look out for any unexpected, drastic drops.

Penalties typically only occur when clear breaches take place, such as duplicate content and plagiarism.

Algorithm Update

Google (and others) change their search algorithms and ranking systems every so often. This is to include new rules, update existing or out of date ones and to reduce the risk of people "gaming the system".

These updates are often quiet small, frequent and go very unnoticed by most people.

Some SEO tools like Rank Math keep an eye on it for you, and alert you in their interface.

Many search engines, like Google, post these updates to the public. You can find Google's on their Search Engine Central Blog.

Backlink

Links from other websites and services, that can direct visitors to your website.

A backlink is created when an external website is linking to your website. This can be both direct links to the home page, a dedicated landing page or be slightly more complex carrying UTM information.

Many search engines see backlinks like a "vote of confidence", if you get good, relevant links from websites with high authority and traffic, it will over time boost your search engine ranking.

Note: The strength of the vote is based on many things, such as click-through rate on the link, the anchor text and relation of the link, the bounce rate when the visitor lands on your site and more.

This effect is also seen in the opposite direction, where linking out, both to high and low authority sites will help both you and them.

It is all about balance, most search engines want to link to real sites with real content, and most real things have a balance of high and low.

Note: While technically all backlinks are good, some are worth significantly more than others. If you for example sell skincare products, getting a backlink from a fashion magazine will benefit you significantly more than one from a car dealership.
