You may ask how Google is offering its searchers more power to revise and personalize their search results.

But what is going on here and what does this mean in terms of online strategy?

Google has made it easier for the consumers to slice and dice their search results.  Clearly this feature makes it easier for the average searcher to create more powerful searches. For the business owner, this is one more step in a Google trend: the overall power of a traditional top 10 organic listing continues to be diluted.

First the top 10 organic was diluted by PPC, which put 3 results above it.

1. Download the necessary archive and unpack it:

# wget http://downloads3.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.zip

# unzip ioncube_loaders_lin_x86-64.zip

2. Find the extension directory:

# php -i | grep extension_dir

extension_dir => /usr/lib/php/20151012 => /usr/lib/php/20151012

First, Google wants to see your content. Make sure you have your keywords/keyword phrases in bold in the text, throughout each page.

Second, make sure that you have an up-to-date sitemap.xml file for your site on Google Webmaster Tools. Generate a new sitemap.xml file whenever you have substantially changed the content on your website to let Google know that you have new information that Google can crawl and add to possible search results based on the new and updated content on your website. You can have many sites create a sitemap for you just use Google to search for a 'Sitemap Generator', for more information regarding sitemaps please refer to http://sitemaps.org for some great information about the sitemap protocal and other bits of information that Google can utilize to aggregate and help bring visitors to your website through positive search results. If you do not know how to upload a sitemap you should go to Webmaster Tools click 'Optimize' then click 'Sitemaps'. You will need to upload your own sitemap to your server and tell Google Webmaster Tools where your sitemap file is.

PageRank is Google’s opinion of the importance of a page based on the incoming links from other sites. (PageRank is an important signal, but it’s one of more than 200 that we use to determine relevancy.) In general, a link from a site is regarded as a vote for the quality of your site.

Google works very hard to make sure that actions on third-party sites do not negatively affect a website. In some circumstances, incoming links can affect Google’s opinion of a page or site. For example, you or a search engine optimizer(SEO) you’ve hired may have built bad links to your site via paid links or other link schemes that violate our quality guidelines. First and foremost, we recommend that you remove as many spammy or low-quality links from the web as possible.

If you’ve done as much work as you can to remove spammy or low-quality links from the web, and are unable to make further progress on getting the links taken down, you can disavow the remaining links. In other words, you can ask Google not to take certain links into account when assessing your site.
