The admin can even make some modifications in order to get proper rankings. Things like XML site maps, Robots.txt file, site optimization etc. comes under it.

Off-page Search Engine Optimization

Another major thing that affects your website is off-page search optimization. This tells about the ranking of your website with a par to other websites based on backlinks, promotion of your website and authority. These factors are important for off-page SEO.

Comparison between the two

Difference between the two is clearly evident from their definition and purpose. Now factors that affect the two of them are also quite different. There are certain factors that affect the on-page search engine optimization. These are mentioned below:

  • Page loading:

If a random user opens your website and it buffers, the user might lose interest and immediately exit from your website. In order to avoid this, see that your site is buffer-friendly. The benefit of fast loading websites is that your website rankings will increase.

  • Content:

Content is king. Good content is equivalent to more users accessing your website. Do not post long and boring content. Instead, post content which is on point and understandable by the users. Content must be engaging and user-friendly. Make sure the keywords are used as per the search engine optimization as it will surely benefit your website. You can go to keyword.com for your keyword research.

  • Alt-text:

Alt text means inserting text into imagery for easy access. The appropriate test must be put for the images. Visuals tell a lot about your website as well as the content you post. Posting images help users get a clear picture of the content you post on your website. Put images that attract your users towards the website. Keywords are a must in this case also.

  • Internal linking:

Another factor that affects the on-page SEO is internal linking. It refers to putting up links related to your website. It keeps your user engaged for longer durations.

  • URL structure:

Uniform Resource Locator or otherwise called a URL is important for your website. Put some keywords in your URL and let Google do the magic. If the keywords are matching and have good engaging information, your website will appear on the top of the search list.

  • Title of your website:

The title also has an influence on your website. Keep a good title with the best vocabulary(keywords) that is under the search engine optimization.

  • Meta description:

A meta description refers to the short description given on every website when we search for a particular topic. This also must contain keywords for better results. It generally appears below the URL. See that the description is short and sweet.

And the factors that affect Off-page SEO are mentioned below:

  • Backlinks:

Backlinks refer to links that direct users to another website. This is also called one-way links or inbound links. It affects your website rating. Putting up more links are helpful for your website growth. Good quality links must be posted. If links are spam, Google will provide you with a penalty. Therefore only choose quality or branded links. You can also go for paid links.

  • Domain authority:

DA or Domain Authority checks your website ranking on Search Engine Result Pages or SERP’s based on factors like backlinks used and many more. The score lies between 0 to 100. The more you score, it is beneficial for you.

  • Social promotion:

Social media influence is a huge one. These platforms act as a medium of communication between users and the admin of the website. We can interact with users anytime, anywhere. When something is posted on social media, it generates a lot of clicks. More traffic is obtained on your websites. Make sure to share links on every social media platform. Be available on every possible platform as we get to see different users on different platforms.


Off-page SEO is out of our control. External factors affect them. On-page and off-page search engine optimization are both important for your website to run. But on-page optimization is given more weight as it has more influence. We can control the factors affecting it. We can modify the URL structure, alt text whenever necessary and it must be updated from time to time in order to obtain high rankings.
