Numbers Are Generally: Response Codes
HTML response codes are informational status codes indicating whether a specific request has been successfully completed. There are five classes: successful responses, server errors, redirects, informational responses and client errors.
200 - This is a success message and it indicates that the action requested by the client was sent and processed successfully. The most common use is when a web page is successfully served up.
301 - Website redirection can be temporary or permanent. 301 is a permanent redirection message and it happens when you are redirected to another URL after visiting a website or page. 301 messages tell search engines that the page the user is trying to access has been redirected and page ranking for the site will be moved to the new address. This is only applicable to 301 redirects.
302 - 302 Found is a temporary redirection message. Similar to the 301, this status code indicates that a web page has been temporarily redirected to another page. Unlike a permanent redirection message, search engines will not pass any ranking to the new page because it is assumed that the redirect is only temporary.
307 - The 307 status code is a temporary redirect message used in HTTP 1.1 protocol. HTTP 1.1 has a required Host header and 307 message is used to temporarily redirect URLs without passing any link value.
404 - This is a “Not Found” status code and is common when a web resource is missing. You should remove any missing web pages and ensure that you create a redirect for all deleted pages on your website. It is recommended that website owners monitor any 404 errors so that the missing pages can be redirected (301) to appropriate content.
410 - A 410 status code tells the client that the web page was removed. When a resource has been explicitly removed, a 410 is used to alert search engines and serves as an instruction to remove it from their index. This is a powerful status code, so use it only when you absolutely want particular URLs removed from search results.
418 - This status code was defined in 1998 as an April Fools joke and is not expected to be used by actual HTTP servers.
500 - A 500 error message means that even though the request is valid, the server was blocked from carrying out the request because it encountered an unexpected issue. This status code leaves search engines confused because it does not provide specific information on what caused the error. If your website is returning 500 errors, you must investigate the cause and fix it.
503 - An overloaded server or an outage can result in a 503 error. It tells the client that the server is currently unavailable. This code should be used when a server is undergoing maintenance, so search engines know that the resource will be available if they try later.
A is for AMP
Absolute URL - This is when a complete URL of a web resource is used rather than just a part
(a relative path). Absolute URLs are preferred for SEO because they do not create canonical problems.
- Absolute URL example: https://www.wolfgangdigital.com/about-us/careers-with-wolfgang-digital/
- Relative URL example: /about-us/careers-with-wolfgang-digital/
Accelerated Mobile Pages (AMP) - AMP is an Open Source framework created by Google and Twitter to help speed up the loading times on mobile devices. It is essentially a stripped-down form of HTML used in creating really fast mobile pages.
AJAX - A web development technique that allows users request data without loading a new page. In summary, it uses a XMLHttpRequest object to communicate with servers. Messages are sent and received in different formats like XML, JSON, HTML, and .TXT files.
Alt Attributes - An alt attribute makes it possible to input an alternative description for every image on a website. If an error occurs and the image does not appear, the alt attribute provides a description instead. Search engines rely on alt attributes to identify what an image contains and this can affect the content indexed.
Anchor Text - An anchor text is the clickable text of a hyperlink. In some online content, writers may want to send the reader to another page or external resource. The easiest way to do this is to add a URL (hyperlink) to a text. This text is the ‘anchor text’ that holds the link.
Affiliate Site - Web sites that promote the products and services offered by 3rd party websites are affiliate sites. Affiliate marketing is a popular marketing program that allows independent marketers (affiliates) to get paid for referring their website users. Affiliate websites are embedded with tracking codes and earn revenue when their users visit or make a purchase through their referral links.

API - Application Programming Interface (API) is a set of processes, protocols, and tools used in creating software applications. Many software services or information-based products use APIs to access remote data. API is used to integrate third-party software into many custom applications opening access to features or data available on an operating system, application, or another service.
Authority - Authority means trust. Being an authority online means that a website or page has a high trust value. Each time people search for something and end up on a page, the website is credited with their trust. Authority can also be earned when other external web content links back to your URL or page.
B is for Bounce Rate

So many experts recommend link juice from high-quality sites and advise webmasters to shun spammy website backlinks.
Broken Links - Any URL that isn’t working as intended is a broken link. This can happen when a website goes offline, content is moved to a different location, or for many other reasons. The occasional broken link will not affect SEO, but several broken links can create a negative signal to most search engine algorithms.
Black Hat - SEO techniques that don’t fall within a search engine’s approved guidelines are called a black hat SEO techniques. These black hat methods are usually considered deceptive in nature, but can also be used to exploit a search engines algorithm in order to gain higher ranking results in a short time frame.
Bot – A ‘Bot’ is an active script or program that can perform certain automated tasks. Robots, spiders or crawlers are the most common bots used today. Search engines use bots to search for and add sites to their search indexes.
Bounce Rate - Your website bounce rate is the percentage of website visitors who leave without visiting any other pages. If you have Google Analytics setup for your website, you can view your bounce rate in detail and use the data to make effective targeting decisions for a lower bounce rate.
Breadcrumbs - Hansel and Gretel used breadcrumbs to find their way back home. This is the same ideology used in websites design today. A breadcrumb is a user-friendly feature that helps website users understand where they are on a site. It will help them navigate easily so they can find their way back to the homepage of the website or back to where they started from.
C is for Crawlers
Cannibalisation - Keyword cannibalisation occurs when several pages on your website are competing for the same keyword or phrase in search results.

Cloaking - The method of displaying different content to search engines from what is on the website’s page. It can also be used deceptively, such as displaying a “quality” page to Google but only serving affiliate advertisements to users who visit the page. Cloaking falls under the ‘Black Hat SEO’ technique.
Competition - Businesses usually know who their competitors are, but these companies may not be the same ones out-ranking your website in the search results. Your competition is that websites that can be found when your chosen keywords are searched by users. For example, all ‘hairdressers in Dublin’ listed in the search result are competitors for the same online space.
Content Relevance - We all know ‘content is king’!, but if the content is not relevant to the keyword we want to rank, it taints users’ experience and the page’s ability to rank well. The relevance of a topic to the content on the page is of great importance for search engine optimisation. The idea is to make sure that the content of a page matches the search query so that users can view only content that is useful, making their experience richer.
Content Relevance is one of the main ranking factors that Google uses for website evaluation, rankings and indexing.
Crawlers - A search engine’s crawlers are responsible for discovering new web pages and adding them to the search engines index. Ensuring that your website is visible to crawlers is important for any website that wants to be found and indexed by the Search Engine.
Crawl Budget - This is the number of pages Google crawls on your website every day. Google states that crawl demand and crawl rate are the two factors that make Google Bot’s crawl budget for every website. The size of a website, health (errors encountered) and the number of links to your website are elements used in calculating crawl rate.
Cross-Domain Canonical - The canonical tag can help you resolve issues with duplicate content. It lets Google know that the pages with tags are copies of the original page. Cross-domain canonical tagging can be done across multiple domains to let search engines know where the original content came from, and to give credit to the content owner.
Canonical (Canonical issues, canonical tag, canonical URL) – Canonical issues refers to duplicate content problems. It arises when 301 redirects are incorrect causing your website to be accessed by search engines from multiple URLs. Search engines could potentially index your site under several different URLs, making it look like you have duplicated content. It can be resolved by using a noindex meta tag and proper 301 server redirects.
A canonical tag can be added to duplicate content pages to ensure that credit is given to the original page.
CMS (Content Management System) - A CMS is a software application that lets website owners modify the content on their websites from a user-friendly dashboard. The user does not necessarily need any scripting language knowledge, as Content Management Systems are designed to be easy to use.

Divs - The ‘div’ tag is very often used within a CSS code to structure a web page. The ‘div’ element is just a container unit that encapsulates other page elements and breaks an HTML document into different sections.
Disavow File - The disavow file lets websites remove any unwanted or harmful inbound links from disreputable sources. This tells search engines that a webmaster does not approve of the source, and helps combat negative SEO or penalties that may arise from the unfavourable inbound links.
Deep Linking - These are backlinks to internal pages. For example, https://www.wolfgangdigital.com/blog/P24/ is a deep link because it does not point to the home page, rather is a direct link to an internal page on our blog.

That is why having internal links is seen as an SEO best practice. Internal links are also important for a site’s navigation.
InBound link - Inbound links are links that are from external sources. These are the same as backlinks and are one of the major factor used in ranking a website. Search engines want to know that your content is so valuable that other sites mention you and provide your links to their users. Inbound links are especially useful when received from high-ranking, authority websites.
Insecure Content - Sometimes website users will see this message when they use a secure connection to access a HTTPS web page and are served a page with unencrypted elements. Some browsers will block the content and ask the user to add an exception before accessing the insecure content.

For example, “party” is a regular keyword with millions of monthly searches, but this keyword is low value because the traffic will not be from your targeted audience. But traffic for “party planners in Dublin” will have a lower search volume, but a higher conversion because it will be from your target audience.

P is for Pagerank
Panda - This is one of Google’s algorithms which attempts to classify websites according to its content quality. Panda uses several “signals” in making this classification. Google rolled out the ‘Panda’ in 2011 and a lot of ‘low-quality websites’ were penalised.
Pagerank - Today, pagerank is utilsed as an internal mechanism which enables Google to index search engine results according to relevance and authority. Back in the day, Toolbar Pagerank was a publicly available metric that gave webmasters a 'score' out of 10 based on Google's own weighting of a site.

Pagination - Pagination is a method of dividing a list of content pages into several distinct pages. If you have a website that has a lot of pages, you may want to add some sort of pagination to make navigation easier.
Parameters – Often we see dynamic parameters being used for tracking. URL parameters should be avoided, if possible, as they can be problematic for Search Engine crawlers, for example, http://example.com? product=1234.
Penalisation - Google can penalise websites that don’t follow their webmaster guidelines and can manually and/or algortithmically manipulate the search results by reducing a website's rankings in the SERPs or even take extreme measures to exclude the website from their SERPs entirely.
Penguin - Penguin was an algorithm update released in 2012. Since then, Google updated this algorithm 7 times before finally baking it into the core, real-time algorithm in 2016. Penguin penalises websites that engage in link schemes. Link farms, link exchange websites and other sites practising spammy link initiatives are all affected by Penguin once detected.
People Also Ask boxes - This is a Google feature that inserts a box of additional queries into the main Google search results. It is a brand-new way for searchers to explore queries related to theirs.
Position Zero (Featured Snippets) - Also called ‘Featured Snippets’ or ‘Answer Box’. Position Zero is the position taken up by the answers that appear at the top of search results and is usually pulled from relevant websites content. The snippet normally includes a summary of the web page and is an advantageous position for brands.
PPC - Pay Per Click simply means that advertisers will pay the website owner or publisher each time a user clicks on an ad. It is used in effective targeting and ensures that advertisers only pay for the leads they receive.
Proxy - Proxies are virtual IP addresses that can be used to change your location. They are used for SEO and allow you to run keyword ranking reports, search results in other countries, extract web data and view local display ads.

Robots.txt - The robots.txt file tells search engines the pages and sections of your website not to index. Nonetheless, while search engines respect your wishes and don’t crawl these areas of your website, if you have sensitive information, don’t assume it is safe to use a robots.txt.
Robots Meta Tag - The robots meta tag allows you to use a granular approach to control how individual pages are indexed on your website and served to users in search results. You can use this tag to control what search engine spiders do on your site.
