On-page SEO is the practice of optimizing individual web pages in order to rank higher. On-page ranking factors can have a big impact on your page's ability to rank if optimized properly.

1. Heading Tags: Header tags, also known as heading tags, are used to separate headings and subheadings on a webpage. They rank in order of importance, from H1 to H6, with H1s usually being the title. Header tags improve the readability and SEO of a webpage
2. Image Alt:  This is also called alt tags and alt descriptions. Alt text is the written copy that appears in place of an image on a webpage if the image fails to load on a user's screen. This text helps screen-reading tools describe images to visually impaired readers and allows search engines to better crawl and rank your website.
3. Internal Linking: An internal link is any link from one page on your website to another page on your website. Both your users and search engines use links to find content on your website. Your users use links to navigate through your site and to find the content they are looking for. Search engines also use links to navigate your site. They won’t see a page if there are no links to it. 
   

Title tags & Meta descriptions are the most important on-page SEO factors. Title & Meta tags are snippets of text that describe the content of a page. The meta tags will not show on the page itself. They will only appear on the page code to help search engines understand the content of a page.

1) Sitemap.xml: An XML sitemap is a file that lists a website's essential pages, making sure Google can find and crawl them all.

2) Verification Tag: A meta verification snippet is a meta tag for verifying that you are the owner of a website. This is used for example by Google Search Console. 

3) Schema Tag: Schema markup, also known as structured data, is the language search engines use to read and understand the content on your pages. By language, we mean a semantic vocabulary (code) that helps search engines characterize and categorize the content of web pages.

4) Google Analytics Code: The Analytics tag is a snippet of JavaScript that collects and sends data to Analytics from a website.

5) Canonical Code:  A canonical tag (rel=“canonical”) is a snippet of HTML code that defines the main version for duplicate, near-duplicate and similar pages.

6) HTML Sitemap: HTML sitemaps ostensibly serve website visitors. The sitemaps include every page on the website, from the main pages to lower-level pages, and can be thought of as a well-organized table of content. An HTML sitemap is just a clickable list of pages on a website.

7) Heatmap Code: A heatmap is a visual representation of where users click on your site.It pulls in data from actual user visits to show which elements on your page get the most attention, and which are being ignored. Areas that get lots of clicks “glow,” so the more clicks an area gets, the brighter it will appear in the heatmap.

We try to work on all the on-site elements we mentioned above on each of the accounts but depending on CMS and the website builder platform there could be limitations in implementation.
