How do various factors influence the results that different search engines produce?

Each search engine uses a different, proprietary, formula to rank results to give for keywords searched.

Google's formula is set to have at least 1,000 parameters that score basically each page found by its robots (spiders)... then put into a huge database.  That data collection is then searched with parameters relative to the searchers (like past searches, location and so on) in order to provide a custom search result.

You and me could be sitting next to each other,doing the same exact search on the same search engine and not receive the same list of results, at least not in the same order.

yes we can change both the color of the value of a cell as well as background color of a cell at the same time .

as we know that excel sheet consists of columns and rows.

and intersection of column and row is called cell.

we can change color of the cell and background of the cell at the same time.

hence the statement that

can a person change color of the cell and background of the cell at the same time is true.

is this supposed to be a question ?
