As part of its recently released list of search quality highlights, Google has highlighted several 0 changes that have been gradually brought into effect to provide more comprehensive results. These include enhanced scoring of news groupings, sitelinks data refresh, better profile pages’ indexing, more pertinent image search results, and much more precise short albeit succinct answers among others. Here’s a quick look at of steps taken by Google to enhance overall quality of its search results:

1. Sitelinks are generated partly by an offline process, which analyzes data like site structure to decide relevant links to show. Google has updated this data through its offline process. News results are organized into groups about a particular story. The engine has scoring systems for determining these groups’ ordering for a given query. A subtle change now improves its scoring system, for effective ranking of news clusters.
2. Punctuation symbols are generally ignored in queries. Based on a thorough analysis of its  query stream, Google has begun indexing heavily used symbols like “%”, “$”, “\”, “.”, “@”, “#”, “+” etc. Expanded sitelinks feature launched for mobile browsers will result in better organization/ presentation of sitelinks during search results.
3. While processing queries so as to return predictions in autocomplete, the search engine usually normalizes them in order to match as much relevant predictions as possible in its database. Autocomplete with math symbols includes characters previously normalized: “+”, “-”, “*”, “/”, “^”, “(“, “)”, “=”, to make it even easier to look for equations, for instance [y = mx+b] or [e = mc2]. Improvements to autocomplete, backends and coverage will produce more comprehensive predictions.
4. Google researchers have updated the sources responsible for their short answers feature so as to depend on data flow from Freebase. The idea is to improve accuracy and also make it simpler to fix bugs. Results for navigational queries have been made more effective apart from high-quality sites algorithm data update (it has pushed updated data particularly for Panda,/ freshness improvements).
5. Refreshed design of News Universal results is aimed at providing more complete results – a bigger font for the top post, larger images and author information. Better indexing of profile pages will make them more comprehensive in its index from over two-hundred social sites.
6. More relevant image-based search results tunes signals it employs related to relevant landing page quality for images even on lower quality pages. Google has also recently effected an update so as to surface more relevant search predictions for image in autocomplete in all languages.
7. The engine has also taken steps towards improving the video results’ freshness to better detect old videos and offer fresher content. Plus steps have been taken for an enhanced app ranking feature and UI on mobile, to deliver richer search results with app icons, prices, star ratings and download buttons to fit well even on smaller screens – on basis of a user’s device platform, for instance Android or iOS.
8. Another change aimed queries with both local intent and navigational in nature (directed towards a specific site) will improve the balance of results it displays, to help find relevant local results or navigational results at top of the page as it fits a user’s query.
9. An array of other changes incorporate improvements to processing for site quality detection, improved interpretation and usage of anchor text, lesser ‘sibling’ synonyms, improved synonym accuracy and performance, better date detection for blog and forum pages, among others.
