What is Crawler –
Search engines sent auto robots to your website which is called “Crawler” or “Spiders”. The role of the crawlers is to collect the data from your website like Text, Content, Links, Page titles and other relevant information. The collected information was stored on the server of the search engine. There is a massive database centre search engine has.
Crawlers are not the human they are Auto robots. So, they were gone through circumstances where they cannot able to understand the information on a website like,
Non-Text content- Crawlers are able to read the text but not able to recognize images, videos, audio files, photos, flash files etc.
Login forms- while collecting the information it seems to be difficult to collect information which is hidden.
Errors in the websites- Error on the website may cause difficulty for crawlers.
Fraudulent information- Duplicate of the same page. This is the major reason where search engines are not tolerated. They are always looking for new information.
A website designer must be understood that they must be tag the Non-Text information on the website so crawler gets the whole information.

Make sure that your content is must be new, informative, relevant and useful to users. Content is the king of your website.

Hence it is the cause for last in the search result.
Search engines always try to give the most relevant information to their users according to the keyword they type into the search box. They also try to give the information in lesser time. Well if your website is not properly optimized then crawlers then even if your website have good content but it cannot be shown on the top result. Here is the necessity of SEO.
