Google Search

Google browser constantly crawls web sites to collect and store the data on a site. The process is called indexing and Google uses this data to match what the users search to show relative sites. So making for Google to index your site easier is the first step for your site to be on top of the search result and we will see how.

Things that Affects the Indexing

1. URL

URL should be human readable and understandable. Look at the example below

For the letters that are not Alphabet, use the ASCII - UTF-8 format

Use '-' to separate words

No ASCII - UTF-8 formats and long IDs can make it hard to index the site

Do not use under score to separate words nor complecated words that are hard to understand

2. File Type

3. Site Map

A site map is an additional information that makes it easier for Google to navigate. This is recommended when the size of you site is big, when you don't have enough links between the pages, or when you have lots of big size contents such images and videos

4. robot.txt

This is a file that manages access to a site or a page. When a site or a page is block by this file, it becomes harder for Google to find them

5. Canonicalization

When you have pages that are identical, you can make a one page to represent them all with canonicalization to avoid uncessary website overload by reducing the unnecessary crawling for the identical pages. This also show only the representative page not others on the search result

 

For example, if you have the same post with different language versions, you can use the canonicalization.

6. Mobile First Design 

Google indexing is mobile first. So make your site mobile friendly for a better indexing

7. Semantics

Semantics are HTML tag that have a meanig (h1, section,...). Use each tag they are supposed to be used for a better indexing

 

For example, use <a> tag with the 'href' attribute to link pages or an external site not the JavaScript event which can make it harder to for Google to index. And use <h1> tag only once per a page as it signifies the main title of a page
