#Develop a web app with SEO
Develop a web application with SEO: -
The responsibilities of a web developer are broader than just designing and developing an application.
If one wants the app to perform well in search engine rankings, incorporating SEO techniques into app development is a necessary evil for every web developer.
When typing search keywords into a browser search box, the search engine must decide how to display results, which web pages are in the top 10 results, and which next.
Search engine algorithms use the data they have stored on each web page to decide which web pages provide the closest content to what the user's keywords are looking for.
The purpose of SEO is to convince the search engine algorithms that the web page is the one that contains the content that the user is looking for.
Besides web page content, ranking algorithms prefer to display websites with the best user experience at the top of the results page.
Combine these two requirements and get the need for web developers who take care of the SEO aspect of a website during development.
As a developer, the responsibility lies with the technical side of SEO, which requires code changes, additions, and tweaks for optimization.
Add relevant HTML meta tags.
Search engine crawlers examine certain HTML tags on a web page to identify the type of content it serves.
The two most relevant tags for SEO are the title and description tags.
If one is writing meta tags for a website then, consider the role of keywords.
keywords are phrases entered by users in a browser's search box.
In order to attract search engine users to the web page, one must first identify the keywords that users are looking for content similar to what one is offering.
Once the relevant keywords have been identified, they should be used in the content of the web page.
The most important places to use the identified keywords are the title tag and the H1 tag of the web page.
Use keywords inside H2 and other headings and paragraphs.
Title tag:
The most effective position for placing keywords in a title tag is its beginning.
If that is not possible, use the keyword anywhere in the title.
A well-optimized title tag should not exceed 60 characters, including spaces and other special characters.
Meta description tag:
Description tags don't have much weight on the outcome of the ranking algorithm.
Robots.txt file and robots meta tags
Use the robots.txt file to instruct search engines not to crawl the pages specified in the file.
In general, blocking crawlers from a particular web page helps prevent crawler requests from overwhelming the application server.
Do this only if reducing the number of requests sent to the server is critical to the performance of the web page.
One can also prevent the crawling of unimportant pages on the website.
One can use the robots.txt file to prevent web pages from being indexed on Google or similar search engines.
If one wants to remove a page from indexing once and for all, add the robots noindex meta tag to the HTML code for the page.
Follow and do not follow links:
A crawler typically crawls linked pages within a page it is already visiting.
Structured data:
Searches lead to page display results in special formats.
Google, and most other search engines, use structured data provided in a web page to retrieve data to display special features like this.
The vocabulary used to write structured data is essentially similar to that defined in schema.org.
If we optimize for Google, we can test and validate structured data using Google's rich results test.
Google offers a handful of other types of features, including an article, FAQ, book, job post, and local business.
Page load speed:
One of the main aspects of providing a better user experience to users is the speed of page loading.
The bounce probability increases by 32% when the page load time goes from 1s to 3s and increases by 90% when the page load time goes from 1s to 5s.
Due to the importance of page speed for the user experience, Google began to use it as a ranking factor in its ranking algorithm.
The increased page load speed is one of the reasons why the web page ranks higher on Google's results page.
While it is essential for the web page to load quickly, it is also essential to make it look like the loading is fast for the users.
The time it takes to display content on the page should be reduced to hold the user's attention while the rest of the content loads in the background and makes the page appear to load faster for the user.
Google's Lighthouse is a great tool for measuring site performance. Its performance score is not just based on actual page speed under perfect network conditions.
It takes into account the performance of the site on even poor 3G connections. Lighthouse is a great tool for measuring the feel of the page load time for a real user.
There are several approaches that can be used to increase the loading speed of a web page.
*Cut down on CSS, JavaScript, and HTML.
*Reduce the number of redirects.
*Take advantage of browser caching.
*Optimize image sizes.
*Enjoy lazy loading.
*Take advantage of Google's Accelerated Mobile Page (AMP).
*Mobile-friendliness.
When most online content takes a mobile-centric approach, Google has also taken steps to factor a web page's mobile-friendliness into its ranking algorithm.
A mobile-friendly website provides a better user experience for mobile users.
When the number of users accessing the web through their mobile phones is at an all-time high, it should be a no-brainer to transform the web application to better serve mobile users.
There are three main approaches to making the website more mobile-friendly.
Use responsive design:
Converting the current design to a responsive design would have the least impact on the existing codebase.
One can set new viewport meta tags, change the CSS to be more flexible for different screen resolutions to make web design responsive.
Use a dynamic design:
The dynamic design serves different HTML content to mobile and desktop users after detecting the type of user agent requesting the content.
The implementation takes more effort than a responsive design, as it must serve pages rendered differently for mobile and desktop users.
Use a mobile subdomain:
Some web applications use a separate subdomain for mobile users.
Typically, the subdomain has a name similar to mobile.example.com or m.example.com.
This approach takes much more time and effort to implement.
It is generally not recommended for small to medium-sized websites, especially if one of them doesn't have two different versions of the website.
