Seo updating content
Stop linking to those sites; you don’t want to have any broken links on your site whatsoever.
While you’re at it, make sure there are no spammy or negative websites are linking back to your pages. One way you can update old content is by adding new pictures to the page.
You can avoid a drop in rankings by getting search engines to recognize your old content again. This doesn’t have to take long – you can simply take out irrelevant information and add a few sentences here and there to make the content current.
Initially, all webmasters needed to do was to submit the address of a page, or URL, to the various engines which would send a "spider" to "crawl" that page, extract links to other pages from it, and return information found on the page to be indexed.The process involves a search engine spider downloading a page and storing it on the search engine's own server, where a second program, known as an indexer, extracts various information about the page, such as the words it contains and where these are located, as well as any weight for specific words, and all links the page contains, which are then placed into a scheduler for crawling at a later date.Site owners started to recognize the value of having their sites highly ranked and visible in search engine results, creating an opportunity for both white hat and black hat SEO practitioners.Do research to find out which ones you should be using.Test them out to determine which ones are most effective. You can do this by providing links to them on the main page.
