Keys to Success

For one’s website to perform well in search engines, certain key factors need to be considered. These factors include:

Use of Legible fonts

The size of font makes it easier for users to read through your content with ease. If readers have to struggle with this then the ranking will definitely be poor. Furthermore, legible fonts make your website engaging and reliable.

Meta Description

Google’s latest approach is to assess web developers have included a unique description or not. However, it is advisable that web owners avoid duplicating Meta description from other websites.

  • The title of the webpage should easily tell the content written. This makes it easy for Google to show your website once various results are typed. It is preferable if you include keywords in the title.
  • Use descriptive texts on the links provided- if you incorporate some guiding text on the link it makes it easier for the algorithm to pick your website during search results.
  • Free you web page from index blockers- it should be made clear that for sites that have restrictions on indexes it becomes difficult for the search engine to rank your content.
  • Make use of canonical or rel=canonical URL- it is often that webmasters have similar content available on the search engine. However, to avoid issues of duplication, it is important that developers link one URL to indicate the original source. The benefit of this is that it makes it easy to rank your website.
  • Avoid using browser plugins- web developers should endeavor to filter out any plugins on their website. This is because it is unfavorable with Google algorithm due to issues such as security and credibility.
  • Web developers should use valid hreflang for attached documents. Basically, web developers are free to choose the language type to write content on their websites. To win big in web ranking it is important to localize your content to the preferred language. For example, a webmaster based in Iceland may localize using URL (en-ie). If he wishes to extend to Germany, let’s say, he should include URL (ie-de). Moreover, a valid hreflang minimizes the occurrence of errors.
  • Incorporation of successful HTTP status code.
  • Meta viewport element- more websites that are accessible to mobile users. Not only should the description be available for mobile use but also needs to be friendly.

The whole concept around the Lighthouse chrome extension revolves around tracking and improving your site on search engine optimization. Most of the digital marketing companies prefer this and it is thus important to use this tool so as not to get stranded in developing your website.
