How to prepare XML Sitemap & robots.txt
When I first started my website 5 years back, I used a 3rd party site to generate a XML sitemap. But it only allowed 500 pages, whereas my site has around 5000 pages in it, and increasing every single day. So both Google and Bing don't recognize the XML sitemap I've uploaded in my webmaster tools account anymore. Worst part is that, Google has only indexed 180 pages (170 of them are invalid pages), and Bing has indexed 50 pages (all valid).
I didn't realize this would be a serious issue, until I figured that 3rd party site indexed tons of invalid pages, and I keep seeing warning messages in Google webmaster tools. The developer I hired for my site's maintenance doesn't know how to prepare such sitemap. I also read about the importance of having a robots.txt file to ease the search bots.
Now, do you guys know any such tool that can help me prepare both the XML Sitemap & robots.txt. Or any freelancer who'd take such work? Please recommend.
Highly appreciate your expert opinions. Many thanks.
Happy Holidays!
