Website audit.

In order for a user to find a page in a search engine, it must first be found by a robot that is sent to explore it by a search engine such as Google. If this robot discovers your site and examines its content, it will save it in its database. The robot then decides whether your content on the site is beneficial enough to show it in search to other users. This process is called indexing.It is very important for search engine robots to be able to index all the pages of a site to be found by a user in a search. Search engines do not want to display administration pages, cart pages, duplicate pages, and other parts of the site that would not be of any benefit to users if they were displayed in search results.The determination of which pages to display is influenced by the commands in the robots.txt file, the robots meta tag, or canonicalization.

The robots.txt file is located in the main directory of the web page. It is the first place a search engine robot will look to see what web pages it can or cannot index. Search engines don’t want to show administration pages, cart pages, duplicate pages, and other parts of the site that would not benefit users by showing up in search results.． The robots.txt file should be placed on every website.

The page title or Meta Title is one of the most important factors in search engine optimization. On every page, the Meta Title must be unique. The title should contain the most important keyword for that sub-page and your brand name at the end. The length of the Meta Title should be less than 60 characters.

The page description or Meta Desciption is important for SEO. The content of Meta Description should be a brief description of the subpage. The length of the text should be up to 160 characters and the text should be interesting for users. The search engine will decide whether the Meta Description content will be displayed in search or not.

The H1, H2, H3 and other tags are the headings and subheadings of each section on the page. The H1 heading is the most important heading and there should only ever be one heading on the page. It should contain keywords that describe the subpage. The other subheadings should logically structure the page and should not be used in a haphazard way.

An example of a logical Hx structure might look like this:

H1
     H2
     H2
           H3
                 H4
     H2
           H3
                 H4

A sitemap or XML sitemap is a file that contains all the URLs of a site. Sitemaps are used by search engines for better navigation. Thanks to sitemaps, robots can discover pages that they would not find in a normal web crawl.

Image alt tags indicate what is in a given image. Alt tags are useful for the visually impaired, who can use them to find out what is in the image. In SEO optimization, alt tags help search engines understand the meaning of an image and place it in the image section of a search.

Each image on your website is stored by the computer in a pre-selected code representation, called a format. Modern image formats such as WebP offer the same quality with a smaller size than older PNG or JPEG formats, which means faster downloads and less data consumed.
